Hello fellow bassheads. I own a 2008 Chevy Silverado 1500 extended cab truck with two DSS 15s and an Ampere 5k. I have previously removed the interior of the vehicle and covered most of the sheet metal with HushMat. I removed the head liner and covered some of the roof metal with this product, however, the bass makes the roof flex terribly. The sound is very tinny and I would like to remove some of the flex. What are the best methods to combat this while still retaining the head liner? The current sub setup has the port and drivers firing toward the ceiling. Would building a new forward firing box remove some of this flex? Thanks for the help.
I used 3 layers of vibraflex in my 2000 Silverado and was able to re-install the headliner with no issues. Currently running 2 emf 15's on ab18k. And roof is solid. Hope this helps.
deadener is for chumps. Wood, fiberglass and sheet metal is the best and cheapest way to control flex. Spray foam works too. All 100x Better than deadener when it comes to flex. Deadener might work for baby systems but bigger systems require actual rigidity. The amount of money you waste on vibraflex, you could have gotten an even more bullet proof roof with the other alternatives and have more money in your pocket.
If i understood clindquist_bass post correctly "any suggestions to limiting roof flex while retaining the headliner" wood, sheet metal, and fiberglass are great suggestions although would be difficult to keep the headliner we can learn a lot from each other if givin the opportunity I choose to be an asset to a solution to those looking for suggestions in accomplishing their audio goals
You this is how we do car around here^ thin sheets of wood and then the headliner still fits and looks like stock... if my truck didn't have 80sq ft of deadened on the roof already it would have wood.
I just did my roof last weekend. Its a 96 crew cab Chevy. From the b pillar back it is only a single layer of sheet metal and no bracing. Was about as sturdy as an empty pop can. Picked up a sheet of 3/16 plywood and ripped 7 1/2 inch wide pieces and attached them between the roof ribs with pl adhesive. The next day I pl'd a full length and width piece of 3/16 to the pieces from the day before to tie them all together. I know a double layer of 3/16 doesn't sound like much but it is solid now. Smack it with your hand and u get a solid thud. B pillar forward is double layered sheet metal with around an inch between layers. Drilled maybe 30 holes in the inner layer a shot spray foam up in there and covered the holes with aluminum tape to keep the foam in and let it expand between the 2 layers.
