Integrating a high performance signal processor like the Rockford Fosgate 3Sixty into a car audio system, especially ones requiring OEM integration, can challenge even the most experienced installer. Through proper diagnosis of the car audio electrical system, tricky issues can be broken down and addressed with small solutions. This document is intended to provide troubleshooting techniques for common car audio installation issues, but is custom tailored for the 3Sixty. For each symptom, there is a step-by-step procedure to identify the cause and recommended solution.

Noise

There are two types of noise common in car audio systems. The first and most common is Engine Noise, commonly referred to as Alternator Whine. This noise is typically a single tone whose frequency changes with engine RPM. Since the engine must be running, this type of noise is not present when the ignition key is in the Accessory position. The second type is the Noise Floor. This noise is not a single tone, rather a broadband signal that sounds like a constant hiss. This noise is a function of electronic circuits in operation and is most prevalent when levels are not matched between different electronic components.

Engine Noise (Alternator whine)

Engine noise is caused by ground loops. This means that grounding points at various locations in your audio system are not at the same voltage potential (0V). If this is the case, the electronic devices attempt to be at the same potential. This occurs when current flows from one component to another in order to obtain a balance. The “crossing” of these currents result as engine noise audible through the speakers. In order to resolve the issue, you will need to locate its source. It can be any grounded device in the signal chain including the source unit, 3Sixty processor, amplifier or even a speaker. Follow the steps below to isolate the source:

1. Unplug the RCA inputs on the amplifier. If the noise goes away there is a problem prior to the amplifier (up the signal chain.) If the noise remains it is likely that one or more of the speaker wires is grounded. Check for screws piercing the length of speaker wires and ensure no speaker terminals are touching metal inside the doors or rear deck locations.
2. Plug the RCA’s back into the amp and remove the RCA’s from the output of the 3Sixty. If the noise remains, the problem is in the RCA’s between the amplifier(s) and the 3Sixty. Check the entire path where the RCA’s are routed through the vehicle. Attempt re-routing the RCA cables away from noise sources like car computers, fuel pumps, motors or other electronics.
3. Plug the RCA’s back into the 3Sixty outputs and remove the RCA’s from the 3Sixty inputs. If the noise goes away, the problem exists between the source unit and 3Sixty. If it remains, the problem exists between the 3Sixty and amplifier. Make sure the 3Sixty and amplifier are grounded at the same point in the car. If they already are, you may want to try connecting a single wire from the 3Sixty RCA output shield to the amp’s ground connector. If this doesn’t help, try using a ground loop isolator on the 3Sixty output instead. If you find that the ground loop isolator is the only remedy, please contact Rockford Fosgate Customer Support and let them know your issue and its source.
4. If the noise does not go away yet, the issue exists between the source and 3Sixty. If using the auxiliary inputs on 3Sixty, disconnect those RCA’s and see if the noise goes away. If it does, it means that the aux source is establishing a ground point different than your amplifier and 3Sixty. Either re-ground the source to the 3Sixty/amplifier grounding point or use a ground loop isolator on the 3Sixty aux input. If you are not using an aux source or the noise remains, please contact Rockford Fosgate Customer Support and tell them your issue and its source.

Floor Noise (Hiss)

If you have identified your noise as floor noise, you will need to determine the source. Every component along the signal chain may be the source. This includes the source unit, 3Sixty, amplifier or any other electronic device in the signal chain. You will need to start isolating components one by one until the noise goes away, this will tell you which component is the offender. We mostly see this issue caused by the source unit so we’ll start there. Follow these steps to locate the source:

1. Noise is most noticeable when the audio is low so turn your source unit to its minimum setting, but not entirely off. For instance if you radio has steps 0 to 35, set it to volume 1 instead of zero.
2. Insert any CD into the source unit and wait for the audio to start.
3. Pay attention to the noise floor, noting how loud it is.
4. Pause the CD.
5. Does the noise floor get quieter or go away?
   1. If hiss goes away completely, you have just identified the source as the source unit. Unfortunately, there is nothing you can do unless you replace the source unit with a high quality model. If the source unit is the OEM radio and you are tapped into the signal after the OEM amp, you can try tapping the signal from before the OEM amp instead; perhaps the noise is from the amp. The same holds true if you tapped the signal from the source unit but your system has an OEM amp. Try tapping the signals after the OEM amp and repeat the setup.
   2. If hiss gets quieter, you identified the source as a contributing factor but not the sole source.
   3. If the hiss did not change, the source unit is not the source

If you answered B or C continue with the steps below…

6. Unplug the RCA’s from the 3Sixty inputs; if the noise goes away, the problem is either the source unit or the high level inputs connected between the source unit and 3Sixty. You can try re-routing the wires in the car away from noise sources like windshield wiper motors, vehicle computers or other electronics.
7. If the noise still doesn’t go away, remove the RCA’s from the 3Sixty outputs. If the noise goes away at this point, the noise floor is caused by the 3Sixty. If this is the case you can try reducing the noise by turning down the output level using the Bluetooth enabled controller and compensating for any level loss by increasing your amplifier gains.

5. If the noise does not go away at this point, unplug the RCA inputs to your amplifiers. If the noise goes away, the problem is in the RCA cables. Attempt re-routing the RCA cables away from noise sources like car computers, fuel pumps, motors or other electronics.
6. If the noise remains at this point, the source is your amplifier. The amplifier gain adjustments are most likely set too high. 3Sixty is capable of delivering 7VRMS of signal level. Most amplifiers input range is 250mV to 4VRMS. The additional voltage allows for headroom in the dynamics of music. Ideally you want the amp gains as low as possible, typically ¼ or ½ at the absolute maximum.

Turn on/off pop

Turn-on / Turn-off pop is caused because your amplifiers are remaining on while your 3Sixty is either turning on or off. Both your amp(s) and 3Sixty need to utilize the same remote turn-on. If they are on different circuits or some use a relay and while others come direct from the source unit or auto-antenna turn-on, you will have issues. Also, the manual incorrectly states that the B+ connector on the

3Sixty and Remote should be connected to a switched 12V source. It should state that the B+ should be connected to a constant 12V source instead.

Bluetooth Connectivity Issues

3Sixty is not discoverable

Check the power indicator on the unit. When the device boots up, the power indicator (red) will flash for a few seconds before turning solid. If the LED fails to turn solid, please contact Rockford Fosgate Customer Support to repair your 3Sixty.

3Sixty is discoverable but cannot connect to it

Many Bluetooth devices retain memory of devices to which it previously connected to. Your device may just remember talking to 3Sixty and show it as discoverable. You can always delete the 3Sixty from your Bluetooth enabled device and search again for available devices. If it is not discoverable, see the note above. If it is discoverable but still won’t connect, it is likely that the password is incorrect. You can reset the password of the 3Sixty back to the default setting of “0000”. Turn the 3Sixty on, waiting for the power indicator to stop blinking, then press and hold (for 1 sec) the pin reset button located on the front panel. Re-connect with your Bluetooth enabled device.

Application crashes when “Tune System” is selected

Download Rftech S.r.l Port Devices Driver

A corrupt 3Sixty file can cause application crashes. The best way to fix this is to reset the unit back to factory default. This can be done by performing a New Aftermarket install and selecting all 6 inputs. This will ensure a proper staring point. After you do this you should be able to select Tune System without any further issues. At this point you can perform another New Install (OEM or Aftermarket) for your application.

Windows PC Connectivity Issues

In Windows, it is important to first establish the Bluetooth relationship between your PC and 3Sixty before you run the 3Sixty application. Every Bluetooth PC application is different so please consult the manual to learn how to discover available devices and services. Once the 3Sixty is discovered and the Serial Port Profile (SPP) service is identified, you will need to connect to it using your Bluetooth software. At this point, you will be prompted for the PIN or PASSKEY. Remember the default value is “0000”. Once you have successfully established the relationship and connected to the 3Sixty, the 3Sixty will turn from red to blue.

If using a PC, you will also notice a COM port number being displayed. If it gives you an incoming and outgoing port, use the outgoing port number only. At this point, you can disconnect from the 3Sixty using your Bluetooth software, making note of the COM port. Now you can run our 3Sixty Windows application. When starting the Windows application, it will ask which COM port you would like to use. Select the appropriate port and click Start Application to begin. When you exit the application, the COM port will automatically close and you will disconnect from the 3Sixty device. As long as you communicate with the SAME 3Sixty, you will never have to use your Bluetooth software to establish the connection again. If however, you want to connect to another 3Sixty, you will need to repeat the process above.

Remote Control

Not Functioning

Check the cable and connectors in the 3Sixty and remote. These pins get dirty and/or bent and the connection between the connector and the cable may be faulty.

Volume fluctuates on its own

The remote knob sensitivity is not linear and some controls are more sensitive that others. You may have luck trying another controller or you can hide the problem by increasing all output levels by +3dB, then turning the knob down to maintain the same volume.

Device Will Not Turn On

Are you using the remote-in or remote-out function? If you do not know, remove the 3Sxity plastic end cap labeled Output. You will find 2 jumpers, “In” and “Out”. If you are supplying a switched 12V signal to the 3Sixty, this jumper should be on the IN header. If you need 3Sixty to supply a remote signal, set this jumper to OUT position. In order for 3Sixty to generate a remote signal, it needs to see a DC voltage on the front left input. Typically this voltage will be half of the battery voltage (for example, if the battery voltage is 12.6 volts, the DC voltage will be 6.3 volts.) This signal will not be present on low-level signals, only high level signal and after an OEM amplifier. To determine if your vehicle has this signal, connect a voltmeter (set to DC) from either the + or – of the speaker wire to the positive lead and connect the negative lead to a ground point in the car. You will need at least 2 volts on this line but you can have up to B+ voltage and 3Sixty will function correctly. If your device will still not turn-on and you, you’re sure your device is connected properly and all signals look good, then contact our Rockford Fosgate Customer Support department, as your unit may need repair.

Input Level

Clip Indicator illuminates even when turned all the way down

3Sixty was designed to take up to 20VRMS into the high level inputs. If the clip indicator remains “on” even when the input level is set to min, you can either set the system up with the source unit volume turned down a little or you can add a resistor in series with each + and – input. You may need to experiment with this value. A good starting point is 20k-ohms. These resistors can be standard 1/10W resistors found at your local Radio Shack dealer.

The Clip indicator never illuminates

3Sixty input sensitivity is 1V ~ 20VRMS. If your signal is lower than 1V, the clip indicator will not blink. You can either turn the input level to it’s max setting or get a line driver to boost the signal before it reaches the 3Sixty.

How do I know mine is set properly?

Ideally, you will want the Blue LED “on” solid and the red clip LED to slightly blink. This indicates proper level. Also, if you run OEM integration, when the process is complete, you will see a frequency response plot showing you the input signals. The red “before” plot should be centered in the plot window. If it is not, you will see either that most of the sliders are raised or lowered in order to get the blue “after” plot centered. If this is the case, please readjust the input levels on problematic channels and repeat the OEM setup again.

Audio

Distortion

You will first need to identify the source of the distortion; it is either from the source unit, the 3Sixty input, the 3Sixty DSP or the amplifier. Follow these steps to locate the source:

1. Set the system to play content where distortion is most easily heard.
2. Turn the amp gain to minimum. If distortion goes away, the amplifier is excessively clipping, thus causing the distortion. If not, proceed with the next step.
3. Are the red clip indicators on the 3Sixty blinking? If so, turn then down until they stop. If the distortion goes away then turn the output level up to compensate for the decrease volume. If not, continue to step 4.
4. Turn the output level down on the 3Sixty using your Bluetooth enabled device. Keep turning the channels down and see if the distortion goes away. If it does, you are internally clipping the 3Sixty, you will have to leave the output levels set to where the clipping starts and turn your amp gain up to compensate for the lower volume. If this does not help, continue to step 5.
5. If you get to this point and the distortion is still audible, it is highly likely that your source unit is the offender. Turn the volume down to the point at which the distortion stops. Make note of this point and reconfigure your 3Sixty and amp to give you the acoustic level prior to the high volume position.

Left/Right sound is unbalanced or sub only plays when source unit balance is set far Left/Right.

In some situations, summing channels may cause an uneven balance in the audio. This typically occurs in systems with a dedicated OEM sub channel. If this is the case, simply connect the OEM high-level sub signal into BOTH the center and subwoofer high-level inputs and re-run the OEM setup. If this is not the case, please contact Rockford Fosgate Customer Support.

Unit not responsive to adjustments

Make sure the Blue indicator on the 3Sixty is blinking. Every change will cause the indicator to flash.

Where should I set the output levels?

We typically recommend they be set to –3dB. If you are hearing audible distortion, turn these levels down.

Small clicks audible through speakers when making adjustments or when unit is booting-up.

Amplifier gains are too high and are amplifying low noise from the power indicator. Turn-down amp gain and turn-up output level from Bluetooth enabled device.

3Sixty turns-on, but no audio coming out.

If you have an OEM source, it’s likely the OEM amplifier is muting its outputs

because it doesn’t “see” the factory speakers. Some amps check for the speakers before playing audio, some will check randomly and some never check at all. If your 3Sixty previously worked and suddenly the audio stopped, it is likely this is your problem. This may be fixed by attaching a 68-Ohm 1/4W resistor (available from your local Radio Shack) across all high level inputs. You will connect one end of the resistor from + to – or FL, FR, RL, RR, Cen and Sub. This will “trick” the OEM amp into staying-on and playing audio again. As OEM amps get more complex, this may not work in future models. If this doesn’t work, please contact Rockford Fosgate Customer Support for an updated procedure.

Auxiliary source is too quiet

If using the 3Sixty.2, adjust the level of the aux source by either boosting or cutting all frequencies in the auxiliary EQ. Typically this can compensate for a low level from portable MP3 players.

Bass is too high in Auxiliary Mode

All channels will play at their maximum set level from the output level screen when in auxiliary mode. The remote will switch to master volume controller. If in normal mode you use the controller as subwoofer level and you switch to aux mode the bass is too loud, you have an option as long as you have a 3Sixty.2. If this is the case, you can tune the auxiliary input indignantly from the normal input. We suggest reducing the subwoofer frequencies (20Hz ~ 100Hz) down
-1db to –2dB. This will reduce the bass and rectify your problem without affecting your source unit response. Note: If you have a 3Sixty.1, we suggest turn the subwoofer level down in the output level screen or install an L-Pad on your RCA’s feeding your subwoofer amplifier.

OEM Integration Setup scenarios

How do I connect all of these speakers, there are only 6 inputs?

This is probably the most complex and confusing part or 3Sixty. While there are a limited (6) number of inputs on 3Sixty, it is still possible to use in a 6+ channel OEM audio system. The following steps will help guide you to setting up your 3Sixty for your specific application:

1. Passive Systems
   1. Most multi-channel systems are passively crossed over meaning the OEM amp sends a full range signal to a driver, which in-turn has a local passive crossover to filter out the frequencies it doesn’t need. This is very popular on systems with a separate mid and tweet. The tweeter gets the same signal the midrange, but an installed capacitor blocks low frequencies. In this case, even though there are 2 speakers, (tweeter & midrange) there is only one channel of audio. This may even be true from a tweeter/midrange/bass (3-way) system as well.
   2. If you are unsure the response of a channel, let 3Sixty analyze it and tell you. Hook up the front left 3-way to the left 3 inputs on 3Sixty and the right 3-way to the 3 right inputs.
   3. Run OEM integration and choose NO to summing. When the process is done, it will show you the response of each channel. If they are all passive, you will see that each before curve looks very similar if not identical. If this is the case, you will only need to grab one for the front left and one for the front right. If they are different, you may find that 2 out of 3 are similar. In this case you can grab the left/right tweeter and use it as the front left/right, and the left/right bass into the 3Sixty rear left/right.
   4. If there is also a subwoofer, run that into the sub input. Run OEM and choose YES to sum.

2. Active Channels
   1. Some cars may have discrete channels. If there are 2 discrete channels in the front tweeter and midrange, 2 discreet in the rear tweeter and midrange and a subwoofer. You now have 9 channels but only 6 inputs. The solution would have all tweeters and midrange down to line-level using line-level converters.
   2. Use a simple Y-adapter to connect both front left midrange and tweeter together into the 3Sixty front left input. Repeat the process for the FR/RL/RR. This will sum those channels to get a full range into each input. Now you only have 5 channels, so connect those into the 3Sixty inputs and run OEM integration and choose NO to summing since its already summed.
   3. Lastly, you can connect both high and low levels to the 3Sixty at the same time as long as you maintain common PAIRS. For example if you use high level on the front left/right, low level on the rear left/right and low level on the subwoofer. You cannot use low level on the front left and high on the front right or high on the center and low on the sub. These channels are paired and cannot be controlled independently on the input side.

The situations above represent a small sample of the types of systems you may come across in the install bay but from them, you should be able to derive your own solution.
