I have a 2003 Pontiac Grand Am GT and I was wondering how I could hook up an Amp and Possibly two subs to the stock Monsoon system without buying a new HU.

Also, would I have to unhook the stock amp? Or would I just leave that little amp in there and hook up the new amp seperately. Any links to "how to's" or any advice at all on how to hook things up would be greatly appreciated.

Yes, I am a newbie at this whole sound system thing, sorry if this is the wrong forum

Thanks again!
