I was wondering if anyone knows how much a decent shop would charge for sound deadening a car. I just got a 12" type x and about to get a pdx 1.1000. My 08 altima sedan has annoying rattles with the stock speakers. I plan on getting my whole car done and getting bass blocks for my speakers so i only get bass from the sub. Id do the job myself but ive never done it before and i want all the areas done good so i think i should leave it to the pros if the price isnt rediculously expensive. Any one have any ideas on how much they charge or know a good spot to get it done in the tristate let me know id appreciate it.
