Think I went a little bit over board with the sub and amp. I have a JL 13w7 and a JL 1000/1 amp. and I it blowing up my trunk. It is way too much bass, and everything rattles. I only have dynamat on the bottom half of the trunk should I go ahead and do the whole thing? Dose anyone know if it will make that much difference. or should i just down grade to a 12" or 2 10"

 

dynamat the hell out of your trunk and it should help

 

Any local audio shops near you? If so go in and ask them how much they charge to spray your trunk with high quality dampening material. The local shop near me charges $25/hour and it takes them about 2-3 hours to do a car. So for $75 I could get my trunk sprayed and never have another rattle again. So check out if any of the local car audio dealers do this, it should be around the same amount.
