Alright guys im having some trouble figuring this out. I have 2 kicker L7s in the back of the nitro and im hitting 148 db's soon to be a couple more. BUT, the back wiper is banging like a monster on the glass and i was told i cant fix it. Also, the back inner trunk is also rattling like crazy and was wondering if anyone thinks dynamat will kill the rattle on the inside plastic also?? what are some possibilities for the wiper ? thankssss.
