RamenNoodles Posted April 18, 2008 Report Share Posted April 18, 2008 Hey all, Today I just got my 12" BTL and my Crunch GP3000D along with my custom box and I installed everything today and to be honest I am not impressed with this subwoofer at all. Like when the subwoofer hits, it sounds like it is bottoming out and I dont understand why. I use to have 2 12w6v2s to a JL 1000/1 and it was hitting WAY harder than my 12" BTL. I just met my friend who I sold my w6s to and he was running them to a Kenwood amp pushing 600rms to them and they were slamming compared to my BTL. I just am not impressed with the performance of the BTL at all. It cannot pick up anything high at all. I know it is a SPL sub, but I have read tons and tons of peoples reviews saying that it actually had decent clarity. I used my dB meter that I have and my best on the 12w6v2s was 147 no sound deadening whatsoever. Now I have my whole trunk competed in FatMat in 1 layer and 2 layer on my trunk. I did a test today and the best I got was 135 WTF?? Does anybody have any idea what is going on?

Thewes Posted April 18, 2008 Report Share Posted April 18, 2008 Theres tons of things that could be wrong. First off what is the sub wired to? Second off, what are your box specs? Thirdly, what kind of car? Quote Link to comment Share on other sites More sharing options...
