Ok, i have the stock amp running the front doors, the Thunder 302 pushing the 12.
A LOT more volume, but like 1sty said, they are a bit harsh.
I dialed down the gain to about 1/2, and it's a big improvement over stock.
I ripped out the stock rear rack, and rewired the entire car with 4 guage power and ground, distribution & ground blocks, gold battery terminal etc.
Also, swapped the Fosgate Stage 1 for a Kenwood 3009 12 inch, and the bass is a lot tighter now. The Stage 1 was very boomy IMHO.
I might try adding 6X9's to the rear deck and using the stock amp to push them as well.
I'm happy for now. (nana)
