stipek Posted June 17, 2011 Report Share Posted June 17, 2011 Just gathering some information to help with my system setup. I have a 2003 Olds Bravada. Does anyone know the peak freq, what box tuning works best, and box/port positioning? If I had access to an RTA or meter I'd figure it out myself but I don't so any relative info would be appreciated. This is for (2) 12's.

spl_blazer Posted June 19, 2011 Report Share Posted June 19, 2011 48-53hz sub up port back seems to do quite well what kind of 12"s and what amps you going to run? is this going to be a daily driver box with descent numbers or all out spl burper?

stipek Posted June 19, 2011 Author Report Share Posted June 19, 2011 This is for mtx tr7500 with mtx jh600 amp. I know its tiny compared to most but just looking to get the best numbers out of a daily. I have them in a sealed box right now and lookin for louder.

stipek Posted June 19, 2011 Author Report Share Posted June 19, 2011 My initial plan is subs up/port back using shared port in the center tuned to 37 hz. 35w x 14h x 20d box (internal dim). 14 x 5 inch kerfed port. Any thoughts? Plan on going to one "local" comp. Rules are music only. Have thought about getting bigger amp. Subs are rated 500W and getting 331W. What output would be a good upgrade?
