oh thanks for the good word on the alpine amp... I actually do know alpine is a good name to buy from. just haven't seen as many people where I'm from with experience with it. I may try that amp. It will be a toss up for me. I'm in no rush to decide. but thank you everyone for your help on this topic for me. BTW, I have an infinity Kappa Perfect 12" sub on the way... I don't plan on putting it in right away. Think this sub will sound nice in my car?
