where is the best place to pick up a new Brahma 15? I was also looking at a place that the ADIRE website recomends for boxes and they only have sealed is this what I should go with or should I get a ported box made for this sub? I figured ported because I am only gonna be giving it 600watts so in a ported box it would require less power than sealed. Well let me know I am putting it in a cherokee so space doesnt matter I just dont really trust the local shops to build the box the way they want so I would like to go in there with specs in hand that way they cabt screw things up. also I should use 1in mdf over 3/4 with this sub correct? thanks again man.

adire's site should have contact info for sales. they sell directly.

as for sealed or ported, use the sub's TS specs and this formula to decide:

Efficiency Bandwidth Product (EBP)
EBP = Fs / Qes
50 or less = best used in a sealed enclosure.
50 - 90 = flexible enclosure options.
90 or greater = best used in ported enclosure.
