Comps and Comp Vr's geniunely are good for what you pay. I will have to say powerbass' have suprised me in their quality too. I bought an 80 dollar sub and banged the hell out of it b4 it finally died on me. I was constantly suprised it kept going. It was 15-m or something.
My old comps are still woofing in my buddies car. Can't beat them for the price.
Whoever said u can get CVR's off ebay for less than 50.. plz link it.. I've never seen it that low, unless their 8's, which i havent really ever looked into.
