Which of these would i use for the remote turn on for my amp?

[peeps]

E10 Drk Grn....

correct me if im wrong but i think the pinouts are labeled wrong. i believe E1-E7 and F1 are all inputs from the stereo. cuz if they arent then that amp has no inputs and way to many outputs. but regardless thank for posting those pinouts it helped me hook up a new amp in my car!!!

[iceman]

Output as in output coming from the head unit.. GM has a funny way of labeling things on their schematics but your assumption is right.

Ok so lets get this straight, I want to add an amp to the factory system, I just splice in a line convertoer to RCA's in front of the amp and use pins E4-E7 as left and right rear speakers outputs from the head unit and also use pin E10 for the amp turn on.
Is this right?

[iceman]

Yes.

I thought u wanted to splice F13-F16 right before the stock amp for your RCA line out converter.. those are the sub channels that would bring the low frequency that u want for u sub.... correct me if im wrong tho.. i did the same exact install a yr ago but cant remember exactly which ones i spliced... it sounds great tho!

F13-F16 are post-stock amp leads.

if connecting an amp in place of the monsoon amp would i use the following:
-correct me if i'm wrong. according to the PINOUTs i would use E4-E7 for the rear connection and E15,E16,F1 and F7 for the front???

i just hooked my stuff right behind the stock HU

[krazzy]

If I am thinking correctly, all of the leads designated with an (E) are out of the stock head unit. All of the leads designated with an (F) are coming out of the Monsoon amp to speakers. With the exception of F1 which is part of the right front speaker leads coming from the head unit.

Not exactly.. the leads are designated as they are - don't confuse people

i just connected my sub/amp rca line out converter to F13-F16 and it works beautifully.... i dont know why both ways of connecting would work but my way works fine... is there any reason i should switch it?

[iceman]

That's fine if you don't want a full range output or if you don't want the crossover controlled by the stock HU/amp.

First off, I have a 2003 Grand Am GT1 with XM Radio. I don't want to remove the Monsoon system but I want more bass.

I have a real basic understanding of how car stereo's work but I am a bit confused as to how to wire the amp up. If I come out of the existing amp and hook up my new subwoofer won't I be wiring the system up to run in parallel? This wouldn't over work the amp but it would reduce the volume of the speakers that share the channel I'm pulling from. Now if I wire the sub up to run in a series I'd keep the sound volume but would be really working the amp hard.

Am I just thinking too much here? I'm following along just fine with what my choices are when it comes to getting the speakers inputs from the factory harness. I'm just not sure as to how this should work.

Also, If I decide to just add an amp to power the sub, would I want to come off of the headunit harness at the monsoon amp or would I want to come off the harness that comes out of the monsoon amp? Any help with exact wire colors would be great!

I Have a 03 GT also w/ xm radio and I can't find the remote wire....E10 the Dark green on I wired in to it gives my amp a signal... but when the car turns off and radio is off the amp is still getting power.....whats up with that?

[fantetti]

well i know with mine the amp will have power for about a minute after the car is turned off. and if i open the doors with the keyless entry the amp will turn on, also if i push a button on the deck the amp will turn on as well.

dont know if this is suppose to happen. but the amp does shut off after about a minute without a signal.

[Vintalage]

Yes, that is what my stock monsoon amp does. All of the mentioned symtoms. This is normal. When you hit the unlock button, the radio turns on and it sends a signal to the monsoon amp to turn on. This allows you to insert a cd when the car is off. That's what I do. That's why I believe it powers up when you hit the unlock button.

Ok.. nOOb question here.. I have a GT (Canada) and I want to hook up a subwoofer to it.. where is the amp located? Behind the Monsoon? This will probably be a temporary measure as I plan to eventually purchase an MP3 player, but at least for now, I'd like more bass.
