rockon1 Posted October 8, 2010 Report Share Posted October 8, 2010 OMG what a PITA !I now have it installed but when I have a song with alot of bass and turn up the volume the sub amps keeps dropping out for a second and then coming back on! This is crazy!!!!!!!!!!!!!!! Any suggestions for that one. Maybe the amp itself has been the problem all along, I don't have any of the problems with the same car. And close to the same set up.

Shelby2u Posted October 8, 2010 Author Report Share Posted October 8, 2010 I put the factory radio back in and it plays great just like it did before this. Quote Link to post Share on other sites
1loudls Posted October 10, 2010 Report Share Posted October 10, 2010 was the bass any louder with the AVIC in there? Quote Link to post Share on other sites
Shelby2u Posted October 11, 2010 Author Report Share Posted October 11, 2010 No its the same however I do have the loud option on low so the speakers in general are a little louder. Quote Link to post Share on other sites
dan02gt Posted November 7, 2010 Report Share Posted November 7, 2010 Did you guys ever find a good solution to this? I have a AVH-P3200BT in a 2006 Mustang GT w/ Shaker 500 and the PAC C2R-FRD1 and I'm having the same issue. I've tried running the head unit off the battery and installing the relay on the ACC and none of this helped. The issue seems to be related to the factory subs and amps. I really believe that the current draw from the factory amps at volume is somehow causing the PAC to reset and this causes the head unit to reset. When I had the relay connected to the ACC I could hear it click back on during the reset of the unit. This tells me that the PAC is either not supplying any power out on the ACC wire or is being completely reset itself. I have contacted PAC about the issue and they are working on replicating the problem so I will see what they come up with. The bass with my AVH is a lot louder than with the Shaker head unit the factory subs actually sound pretty good. I think this is because I can adjust their level and crossover point relative to the highs. So I'm that I'm pushing them harder than the factory head unit ever did and I wonder if this is causing more current draw than the system was ever designed for and it the root of the problem. Has anyone tried connecting their powering their PAC off the battery? I'm thinking about this as I already have the 14ga wire that I ran for the head unit so it would be a easy thing to do.

Dineau Posted November 8, 2010 Report Share Posted November 8, 2010 Could this issue becaused by an incompatibility of the output from the radio to the amp, causing the radio to rebout ? Impedance too low, loading too much the output of the radio ? Has anyone tried with aftermarket amps to see if it does the same thing...? Quote Link to post Share on other sites

I also noticed on mine that I had both the green and the purple RCAs connected. I know the purple is unused but have no clue if it goes somewhere or is just a open circuit. If it goes somewhere it may be causing feedback to the head unit. To me the issue seems related to the factory subs and amps. I disconnected the purple RCA but have not really been able to do a good test to see if the issue is fixed. These head units do put out like 4 volts on the pre-amps maybe it's too much for the stock amps and there is some type of feedback that is causing the head unit to reboot.

Dineau Posted January 17, 2011 Report Share Posted January 17, 2011 For those of you having issues with the reboot when using a PAC module in a Mustang, I found this interesting thread from a Mustang Forum solving the reboot issue: ======================================================================== " After a little bit of diagnosis/trouble shooting with an engineer at PAC we found that the Shaker amps are backfeeding 12v into the C2R-FRD1 unit when at high load (we speculate this was originaly to tell the Ford HU to lower volume output). This is causing an overvolt condition in the C2R-FRD1, the elctronics are designed to operate at 5v. So when 10+v was put into the unit the chips started to malfuniction and then shut down. The Diode keeps the voltage from backfeeding the unit, I used a 1N4005. I think you can get these at your local Radio $hack, Anyway the diode did the trick, no more cut-outs, no more reboots!" ======================================================================== So far all poster have reported this has a valid fix for their reboot issue....

1loudls Posted January 18, 2011 Report Share Posted January 18, 2011 holy crap thats a crazy ideal, some one please try placing a diode inline with amp turn on wire and see if this works, the line on the diode should be pointing toward the car and away from the harness module Quote Link to post Share on other sites
Dineau Posted January 18, 2011 Report Share Posted January 18, 2011 Keep in mind that this only apply to reboot due to playing music at high volume.... You will also note that the person that did validate the solution works for PAC in the R&D group (poster Iskwezm) I don't know if it's permitted here, but here is the link to the original thread from the Mustang Forum: http://mustangforums.com/forum/audio-visual-electronics/622606-06-pac-c2r-frd1-wiring-harness-help.html Solution is on page 3...
