armykyle1 Posted July 13, 2014 Report Share Posted July 13, 2014 Not reading all the posts. But if you add MDF, metal or really anything but sound deadener, you'll be put in extreme classes if you ever compete. Even spray foam in existing braces will cause you to be in higher classes. I used alpha damp. Which has a very thick aluminum layer and it helped greatly with flex. Not so much on resonation of the metal but definitely flex. Similar deadeners will help.

cc_audio Posted July 13, 2014 Author Report Share Posted July 13, 2014 Best roof bracing I've ever seen right here. He's using a stripper pole but I'm sure if you did a good job with MDF and fiberglass work, it would stop it just fine IIRC it's MDF and fiberglas That is one of the most impressive coin flips I've ever seen. It doesn't move AT ALL. Does he have a build thread with some detailed pics I can dig through? youll have to be carefull alot of orgs will not let you brace the roof in front of the b pillar or if they do it has strict rules for it or youll end up in the same class as the stripper poles Glad someone got to this before I did. Any sort of bracing in front of the B pillar in some glassed/orgs will stick you directly in that same class. What class/org are u gonna be running in? Btw a solid MDF/glassed roof works as good if not better from personal testing (Caravan panel van w/ 8 15s in a 4th order). I'm moving from Iowa to Virginia in two weeks so I'm not familiar with any organizations that are down there. Truthfully competing will be an after thought for the most part, its never been important for me here. If any bracing put me in the higher class then so be it, I just don't want a stripper pole. Don't want the blind spot nor the interference. Even though they are practical and come with a real "WOW" factor. Not reading all the posts.

I used alpha damp. Which has a very thick aluminum layer and it helped greatly with flex. Not so much on resonation of the metal but definitely flex. Similar deadeners will help. Then I'll have to run the higher classes, I know my windshield is going to be a serious issue. The flex is already absurb with two ZCONS in a temp box on 1k out of the trunk (about a half inch). Imagine when I stick all four in there in a low tuned 4th on the AB1100.1? It will not stand a chance even with the best deadener. I need to get some steel on that cross member. Any other builds people know of? I'm going to keep digging. Already got a couple ideas from MADDRUNX's build, his roof bracing is phenomenal. Know of any others? It's all gone!

hispls Posted July 13, 2014 Report Share Posted July 13, 2014 Has anyone ever tried adding lead flashing to a roof with say PL adhesive or epoxy? I'd think that adding a layer or two of lead to a roof would quiet it down some.... if you don't mind the extra mass and cost. Link to comment Share on other sites More sharing options...

gckless Posted July 14, 2014 Report Share Posted July 14, 2014 I'd like to see the best bracing while keeping the stock headliner. Easy to make something solid if you don't care how it looks, but keeping the factory headliner is hard. "Clipping" is the biggest forum boner now. It's like witchcraft... it automatically explains just about everything people don't understand.

fecupe2001 Posted July 14, 2014 Report Share Posted July 14, 2014 I'd like to see the best bracing while keeping the stock headliner. Easy to make something solid if you don't care how it looks, but keeping the factory headliner is hard. no need for stock headliner, you can add some wood and just get a new headliner that fits, not a big issue, that´s what im planning to do next week I´m the SPL Gains topic creator!! wanna get louder?? check this: SPL Gains.

philrab Posted July 14, 2014 Report Share Posted July 14, 2014 Shoot this idea down if it sounds totally nuts, but what about some low profile corrugated/tiangulated metal epoxy'ed to the inside of the roof skin? Thinking like a corrugated roof, but scaled way down. The triangulation should resist the roof's inclination to bend due to it's geometry, you'd need to epoxy because you couldn't weld in the middle of it (and it'd have to attach across the entire roof skin and not just at the edges. Then, put the headliner back up and it wouldn't be visible. Like I said, it's probably one of those wild ass way out in left field ideas, but it's based on sound geometry and engineering principles. 2015 Toyota Tacoma Build Thread 2007 Mazda 3; 5000K HID's, Kenwood Excelon KDC-X997, Infinity Reference 6.5 comps in front and coaxials in the rear doors, JL 320.4 four channel, Rab Designs built ported enclosure with an SA12, Kenwood monoblock, Redline Leater shift boot/e-brake boot/center console cover, JBR short shifter/shifter bushings/rear motor mount.
