I just installed 2 12" subs in an 04 GTO and it sounded great. However, you can upgrade the rear deck subs with a something able to handle more power and then adjust the stock amp. The stock amp is set at about half power to the deck subs and does have a gain adjustment. This is a conservative setting and with a nice aftermarket sub would be able to be turned up. It really just depends on how much bass your looking for.
