I do give you props for the work involved in the wall, doors, and dash the fiberglass work looks good //content.invisioncic.com/y282845/emoticons/thumbsup.gif.3287b36ca96645a13a43aff531f37f02.gif
he has 6 clarion 1500's. i think hes seeing 10,000 watts. yes i have pics of the truck, ill upload. hold on a sec. the whole car is deadened, layered ALOT. so theres not much flex. u can barely hear it outside the truck, but inside its insane.
