First off, this is for my v36 g35 sedan. I posted in g35driver, but that forum is pretty much dead.

I noticed that my G35 has an extra wire for the amp turn on for the subwoofer than the bose diagram specifies. When I use the specified amp turn on wire, I don't get enough power to turn on my amp. I only get around 9v. And I'm sure my power and ground are strong enough.

Any suggestions?

 

If it is the right remote wire and your getting voltage but only 9v, that's weird. Stupid question, but have you tried with the car running?

Don't use the sub amp turn on. Tap into the amp. turn on wire on the main plug to the main Bose amp. It should be a white wire in terminal position 20 if I'm not mistaken. Thats what I used and it worked great. If that doesn't work, it's power or ground causing the issue. Test both of those.

 

Yeah, I'm not sure if it's 9v exactly. But all I know is that it isn't 12v. With the car on all the way and on acc.

The other amp turn on wire won't turn the amp on either. My power and ground are perfectly fine because it powers my brothers amp with auto sense turn on and off. And also the amp in question works because I used a wire connected directly to 12v and input that in the remote slot and got power.

I solved the problem by trading my brother amps for his 500/1v2. It has an auto sense remote option that automatically detects when the car is on without needing a power lead. Not sure why I have that extra wire in my subwoofer connector but I'm guessing that's the issue.

 

That's weird then. I don't understand how you would have an extra wire from the factory on the sub connector. You are sure you're tapping the right wire, on the right connector, and using the right A/V diagram for your year and options level? Do you have the base audio, premium Bose w/o navi or premium Bose with navi?

 

Hi, I hate to wake up an old thread, but I am having the same problem. I registered on the forum just to post about it.

Just spent the late afternoon/evening installing my sub in my G35xS 2008. I had it installed in my 2007 Camry SE before and now I got a G35xS.

I thought it was going to be a walk in the park compared to the Camry because of the Bose amp already supplying all the audio connections/remote wire needed right in the trunk.

My equipment:

- 2 x 10" Rockford Fosgate P2D410 dual-voice-coil (DVC) 4ohm woofers (250w RMS each)
- 2 x Rockford Fosgate P300-1 300w RMS 2ohm mono amplifiers

Got the 12v from the battery. It is in a splitter for the 2 amps.

2 grounds are to 1 of the bolts of the stock subwoofer.

Audio sources are from connector B41 pins 23, 24 ,25 26 (Rear LH/RH).

Was trying to use pin 20 or 22 for the remote wire. When my amps are not hooked up to either of these wires, they provide 9V to the Bose amp when powered on. When I hook up my 2 amps to either of these wires (all in parallel), I only get 2V for my remote ??? how is that even electronically possible? I could see losing amps, but volts?? how?? why??

Needless to say, my amps do not power-on using either of these wires (pin 20 or 22). To make matters worse, when hooked up to pin 20 (Bose amp on signal) my 2 amps and the Bose amp itself doesn't come on. I imagine this is due to unexplained the drop from 9V to 2V. I also imagine that the stock sub amp doesn't come on either when I use pin 22 for the same reason but I didn't test this theory.

When I use pin 10 or 11 from connector B42 (12V power for Bose amp) my amps turn on and work great so my power and audio are good. I can't use these pins for my remote wire because they always provide 12V even when the car is off.

Any help or insight would be greatly appreciated! Any ideas why this is happening or where I can get an easy alternative remote wire source?

I imagine that most people have success using pins 20 or 22 from connector B41 for the remote wire because their amps probably accept anything > 0V as an indication to turn on. My amps seem to be picky. The 9V supplied by these pins would probably be enough but it drops to 2V when I hook up my amps so they don't turn on.

I have the 2008 G35xS with nav.

Thanks a lot!

 

 

I can not find the pin 30 connector b241anywhere. Help! Same problem romote wire powers amp and sub when i put it on a constant 12v but cant find anything in the trunk that will power it and turn off when car is off. 2010 coupe with bose. Cant find anything about the backup camera harness. My amp is a rockford fosgate punch p250.2

 

At this point I think ill just have to try and use an amp that does not require a full 12v to power on. it would appear that this is a common problem with the Rockford fosgate amps.

 

I had this same issue with my RF Amp. I ended up running my remote wire to my fuse box (by the driver foot area) and just wedged the wire in there with one of the spare fuses. Works great and have not had any issue with it or anything else.

 

which fuse. I tried running it to the amp fuse last night and it stayed on when I turned the car off.

 

i dont remember to be honest with you. Really anything that is an accesory should work (cig lighter, ect.)

 

Well, I cant say I figured it out. I really didn't like the idea of tapping into a fuse. I ended up trading amps with a friend. now im running a kicker. I tapped into the b41 pin 22(gray wire). works just fine now. I guess the moral of the story is if you have a Rockford fosgate amp pepper ur angus, its gonna be trouble in a G37.

 

I really didnt have much trouble with it. What it came down to was that the remote wire for the stock Bose amp was too thin to put enough power to the Rockford Amp. I mean if you're happy with your kicker amp, thats great, but when i planned my system out, i was dead set on getting that amp for my sub (all the specs were perfect for each other). Did you try putting the wire into the fuse box? Would shouldnt have had to cut anything, simply take the fuse out, shove the wire in, then push the fuse back in to hold it. If i recall correctly, the fuse location i used was just a spare spot in the fuse box... but I dont fully remember.
