conley916 Posted March 4, 2014 Report Share Posted March 4, 2014 So I bought another truck (haha) a 2003 extended cab chevy silverado and am keeping this one for a while and after talking to my buddy about system ideas we came up with two level 4 18s on a 3.5k walled tuned to about 34 hz, if anyone knows about these extended cabs the roofs are like tin cans so with dynamat and the wall for the subs we figured it would brace the roof and not flex as bad. Never done a wall setup so if you guys have some ideas that would help! Quote 2015 Dodge Challenger Scat Pack audio coming soon Link to comment Share on other sites More sharing options...
BLuejoules Posted March 4, 2014 Report Share Posted March 4, 2014 You do need to brace the roof on that truck. Are you set on a wall? You can fit 2 18s below the window line. 1 Quote IG: devinthydude Link to comment Share on other sites More sharing options...
tdsa23 Posted March 4, 2014 Report Share Posted March 4, 2014 Why not 4 18s?

Swordlordboy1234 Posted March 4, 2014 Report Share Posted March 4, 2014 Why not 8 18's ? I second the roof brace thing. Or some kinda extra support. Crap load of deadener?

I'm not set on a wall but I'd be down to do one and my buddy is going to be helping me build it. We were looking up specs and I need 12cu ft for ported so we figured walling it would be easier and would double as a brace for the roof.

Swordlordboy1234 Posted March 4, 2014 Report Share Posted March 4, 2014 I was playing man. I was making a exaggeration to the 4 18's thing.
