I'm bypassing the rear deck woofer (2009 G37x Sedan w/ Bose) to hook up my Rockford P5002 with Sub and having problems with the remote wire that previously turned on the Bose woofer amp. My DMM tests it at 12V, however, when I patch it into the remote port on my Rockford amp, it drops to 4.5V and does not turn the amp on.

The remote wire I am splicing is B43, wire 3.

Additionally, the RCA splitter I have feeding the Rockford from the Bose woofer output gives only a buzz when I plug it into the Rockford RCA ins (bridging REM to +Terminal for power on). When I test each RCA with headphones, they are getting a clear audio signal. Ground loop perhaps?

I've tried:

1. Two different ground points - ground is strong, and attached capacitor is charged.
2. Plugged iPod into RCAs on amp while bridging REM to +terminal. Amp powers on fine, and plays ipod fine. It just buzzes when I give it the RCA signal from the Bose woofer out (which I've verified is a clear signal when not plugged into the Rockford)
3. Tried using Remote wire 20 on B41 instead (main Bose amp remote/on from HU) and it loses enough voltage that both the Bose amp turns off and my Rockford fails to turn on.


It seems like A) I might have a ground loop with the RCA ins buzzing. and B) My Rockford's 12V Remote terminal could be pulling too much current which is causing a drop in voltage. Any other ideas? Any suggestions to remedy these things?

 

Where did you get the main 12v power from for the Rockford?

 

Main 12V from the Battery + Terminal, and grounded to the Frame rail behind the rear seats - pretty standard. Amp powers up and plays audio just fine, but the remote 12v wire won't work with it.

 

In my case it was B, the RF amp and processor pulled to much current and lowered the power turn on signal to about 3.3V. My solution was to insert a PAC TR-7 Universal trigger module. Problem solved

Wire a simple 5 pin Relay and it will solve your issue.

But yes a PAC TR-7 can do this as well, just much more expensive than a simple Tyco Relay, same amount of wire hookups, less the programming of the TR-7
