Decaf Posted December 14, 2011 Report Share Posted December 14, 2011 what does that wood piece in all the corners do? an im not an average joe when i comes to the cost. im willing to spend the money to get it done right. its only in the high pressure corners near the port... helps the air move supposedly. some guys gain on the meter some don't. if you dont care about money go for all thread, thicker the better all thread isn't feasible in every build either. you cant run all thread top to bottom or side to side in a wall build without removing windows or building the box outside of the car. also u have to leave room for bolts on the outside which some hate because it ruins the aesthetics Link to comment Share on other sites More sharing options...

Decaf Posted December 14, 2011 Report Share Posted December 14, 2011 sorry OP, never saw first post somehow 1 5/8s to 2" coarse drywall screws are the typical type to use i use a 7/64 2" long bit to predrill so the wood doesnt split birch if you can find 9ply or higher would be best as its lighter and stronger compared to the same thickness mdf. titebond II works great what sub?

ALPINE408 Posted December 15, 2011 Report Share Posted December 15, 2011 all thread is an expensive brace when u have extra wood laying around ill use round/square dowels any day over all thread, mostly because you can easily screw/glue wood together to make one solid interior brace. with all thread you have more small bracing that doesn't intersect and needs to be welded to properly secure it wooden dowels only stop flex one way and its the wrong way.. wood even the dowels still flex all thread will not flex and takes up lil to no air space i would not even consider useing wooden dowls for bracing i use to way back when before i knew how to get loud im talking about using dowel like this... most guys cant get metal rods cut, but can easily get wood cut. so for the average joe who isnt doing 155db its more than fine. this site consists of far more average joes than guys like you alpine who compete... so cost comes into the equation and all thread aint cheap ok i see your point there... yes wooden dowels will be better than nothing at all for 45's in the corners 98% of the time it hurt my numbers the only 45's that worked are near the port but you would not be able to tell any of this by the ear only the meter can tell Have you ever had your woofers blown?
