Can you hear me now?

car audio --- cheaper from what i've seen. Thanks all for the replies. haven't bought anything from Costco in like 3-4 years. i'm going to shop all those places, to see what i will need. here is a big question --- will JUST a sub and amp make my house rumble? Not looking to spend more then $200.... like I said, i got a BL savage on the way. Which wont be cheap. i had just heard that for under $200 i should get a sub and a amp that will rock. Then use 1-2 stock speakers for trebble (sp). It is only like a 100W system, probably less. If i cannot use my crappy head unit, i'm out. my stock system did some with a seperate powered sub. but I'd like a bigger one. I thought i'd need an amp --- or no?
