I've been looking into a subwoofer for when i'm ready to upgrade, and i've read numerous good things about the JBL W1*GTi-MkII . I only have 600 watts @ 3 ohm, so would this JBL W15GTi-MkII be a bad choice? I'd like the the woofer to get low while still covering the higher sub frequencies.I had thought of getting a JBL W15GTi-MkII with a Sealed 2cuft enclosure or possibly a ported JBL W12GTi-MkII, I want something that will blend well with my HAT 6.5 Clarus, so i'm not sure on what would be a better choice. I'd like the woofer to sound great no matter what genre is being played, I normally listen to Trance, hip hop and some Dubstep.This would be going in a '01 Chevrolet S10-Blazer 4 door (SUV) and the amp i have has a built in Sub sonic filter @ 25hz, so not sure if that will also determine what I will end up going with. I don't have the space for a ported 15" either...
