it sounds good on songs in the 28 to 29 range and up,probably not as loud as it could be , my sealed side is 2 cubes per sub.. minimum recommended.

[Mr Bigolsworth]

I'm doing 3cubic per sub but mines 18's. 6 sealed and 15 ported tuned at 44hz

started taking down the headliner today. wasn't that hard to take off,but couldn't get it out of the truck.

Quad cab you need to fold it. Or pull the rear window out. My ext cab is a lot easier

[moredbs]

the factory dvd player and sunroof, made it more complicated. too many wires glued to the back of the headliner, and to many metal parts in the way for deadener.

i tried taking it out the back window, but theres so many wires glue to the top of it. i started pulling the wires out of the glue, and it actually started to tear up the headliner. ill just work around it i guess.

working at night with a light, still sweating like crazy lol. going to do 4 layers, the first 2 are done. all the factory braces have black foam in them already, i guess thats a good thing.

[ToNasty]

If you have foam in the braces the. 4 layers shouldn't be needed. 4 might also be too much. Might note the console fit back on.

My silverado has 2 layers with no foam
