Yup I'm in the same spot I've got an alpine swx 12" 3,000 watt peak power and 2 kicker cvt 8" replaced the door subs powered by a separate amp. Plus all new kicker speakers.
Saw a 225 alt for 08 GT thought might work but wanted to get some knowledge before hand.
I'll call the shop where my motor is and see what they know, wanted insight before the weekend.
