Well i'v been doing my homework, I decided on getting one Brahma MK II 15" sub. I want to put it into a ported (vented) box so i can get the most out of the sub. And what would be a good AMP to push this driver, i was thinking a BX1000D

Give me some box specs that i should build off of, Size and what to tune the port to.

I drive a 01 grand cherokee if that helps.

Any help would be a great!

Param 15"

Fs 26 Hz
Vas 113 liters
Pmax4 1600W RMS, 4800W peak
SPL5 1m 87.6 dB @ 1W, 1m
Diameter 15.5"
Cutout 14"
cubic feet 0.18
pounds 41

NOTE: Power rating is thermal only! It is NOT a power requirement; typically you get full output with significantly less power than the ratin

so make a box thats over 113 Liters and cut out a hol that is 14" in diamater and find an mono amp that is close to 1600wrms pending on the amount of power ull want to get out of this sub

you dont need 1600watts for that brahma.

1600wrms is just a thermal rating, you can reach the mechanical limits of the sub w/ much less power, that BX1000 should do.

you can BURP the sub at a higher watage, but that is more of a comp thing. you will risk blowing the sub!

deminsions for box designs can be found on the Adire audio site.

1000watts is plenty!
