I recently had two 12w6's put in my truck. They are mounted in a long box thats sealed and are running off a phoneix gold ti400.2. The problem I am having is that with some music (EX: Korn - Freak on a leash) the subs distort like dirty bastards. They cant hit the sound right for some reason and get a very nasty vibrating noise. This happens with a lot of songs from the Korn Follow the Leader cd. This type of music is just not playing right.
I've spoken to the installers and they said I should get a new Head Unit with a crossover and eq built in. Currently I have a 10disk kenwood changer with RF mod. and factory radio and factory eq. I do not know if this is them trying to get more money out of me or honest advice of what I need. I've also heard that I should get an external 3 way crossover rather than a built in one into the radio from a friend.
Please give me some solid advice on how to balance out this problem and best tune my system. Zane, I know JL Audio subs seem to be one of your favorites so I thought perhaps you could offer me the best insight here. Could this perhaps just be a kind of music that does not play well on any system? If you listen to the song I listened to above you'll know EXACTLY what kind of audio is causing me problems.
