2 DP21"s, Almost Done

Ok, there has been a slight change of plans. I have two SAZ-3000D's on the way, so I'll be using those instead of the JL's. Weather I use two with the gains lower, or one, I haven't decided yet.

 
Spectrum sludge is the only sound deadner;)
i definitely like using liquid better now but have yet to try the sludge. I like the cascade vbx from PE it works great. I doubt i will ever buy any matt stuff ever again.

Did you brace the roof at all to minimize the roof flex or just deaden?

Just 4 layers of the Pro. What's the advantage to the liquid type, isn't it all sorts of messy.

 
i just found it easy to work with on walls and floor just poured it into the spare well and started rolling it out everywhere. let it set for 3 hours then again. builds up fast and no having to cut strips and dick around with matt. a roof I would still use matt on if its over carpet while i use it but a big roof like yours I would add some wood to for rigidity. I did it on my van about ten years ago and it helped alot.

How would I go about adding bracing without actually bolting through. I don't want bolts sticking out of the roof of this one.
