IndianaBassHead Posted August 10, 2012 Author Report Share Posted August 10, 2012 2 to the side should suffice honestly..just space them evenly and flex shouldnt be a giant issue..also one you may want to think about is back to front.. wheres the plan to mount the amp? going to mount an amp rack on the front of the box behind the front seats. And it will be tough to brace from front to back since it will be about 65" deep.

pa-pa-platypus Posted August 10, 2012 Report Share Posted August 10, 2012 then i would for sure double up on the back and the front pieces that dont have bracing on them..as they would be potential weak points Quote This isn't teeball.

IndianaBassHead Posted August 10, 2012 Author Report Share Posted August 10, 2012 You could always another another baffle or 2... I would, but height is also an issue. The way the headliner comes down on the sides, there won't be much clearance. I will double up on the front and back pieces. and how do I figure in bracing displacement inside the port?

IndianaBassHead Posted August 10, 2012 Author Report Share Posted August 10, 2012 Any help on how to calculate port bracing displacement? How would a threaded rod effect tuning?

pa-pa-platypus Posted August 10, 2012 Report Share Posted August 10, 2012 Any help on how to calculate port bracing displacement? How would a threaded rod effect tuning? very little if at all...it might lower it .3 hz or some small amount..i wouldnt worry about it Quote This isn't teeball.
