Hello, There are so many choices out there i dont want to have missed a good one, so im asking you car audio gurus what you think is a great subwoofer to put in my truck. I have mostly looked at the JL Audio 12W6's as this will probably be going into a 1 cu.ft. enclosure. What is the best quality sub i can get without breaking the bank. I am interested in both sound quality as well as DBL. If you can post some numbers id really appreciate it. FYI, JL claims 20hz for this one.
