Id like a great thumping system. I already have the sub (10" alpine type-r) Im not sure wht amp to use to power it. Im a label whore and like to keep everything the same but if I deviate I wont die lol. Also whats a good 4 ch. amp to use?

 

i think you pretty much answered your own question. alpine makes some decent amplifiers.

 

I have an Alpine Type R 12" and am using the Alpine MRP-M450 to power it and it sounds great
