I recently began a build that has been plagued by nothing butt problems...im running 2 12" fu 300's a ppi p1000 amp and a box designed by shredder2...after finally getting everything together and finishing the box I must admit I was vaguely impressed with the bass output, however after about 3 weeks one sub has developed a strange rattle...only hear it in the higher bass notes the lows and really hard punchy bass sounds fine. So is the sub blown? If not any ideas what might be wrong?
