Now the Adire Brahma 15' can handle up to 1600rms max with the right setup and box. Say i got the right setup and box. With this Rockford Fosgate Punch 800a2 amp thats 200rms x 2 channels @ 4 ohms OR 400rms x 2 channels @ 2 ohms. Do you think this amp can make this sub hit hard.

200 x 2 watts rms 4 ohms with less than .05% thd from 20-20KHz

400 x 2 watts rms 2 ohms with less than .10% thd from 20-2-KHz

Im not good at configuring amps so is there a way i can configure the amp to get the max out of it for the sub?

Thanks for your help. I appreciate it.

800 would be fine, but clipping will be come a concern when u start to turn it up, put atleast 1100 watts into it, look into the hifonics brutus 1500d, a really good match for the brahama, i beileve ikeaudio sells the amp for 260

I also have a phoenix gold amp thats rated at 1000watts. I dont have the specifics but im guessing it might be somewhere around maybe 500rms x 2 channels MAYBE. Just a guess. But the amp is powerful. I just wish i had the specifics on it. If i bridge these two amps together it should give the sub enough power right?

DO NOT BRIDGE THE PG AND RF AMPS TOGETHER!!!

bad things WILL happen...lol

seriously, dont "bridge" the two amps together...it just doesnt work that way.

if that PG amp is 1000rms...i'd use it.


the brahma will do pretty good w/ 800wrms. in fact on the adire audio site it says that the Brahma 15" will reach xmax @ 800wrms in a 2.85 cu ft sealed box. if you were your, i'd go w/ a ported box though, they can put out a little more SPL.


i ran the brahma 15 in WinISD (a speaker progam), and in a 4 cu ft box tuned to 30hz the brhama 15" will be just under linear Xmax @ 40hz....so 800wrms in just such a box would be fine.

The Brahma usually doesn't even need over 1000 watts typically. Here is the Brahma Power Chart:

Brahma 10
Qtc Box Size (L) Box Size (ft3) Power
0.5 24.7 .87 700W
0.577 14.0 .49 1000W
0.707 7.5 .27 2000W
0.8 5.4 .19 3000W
0.9 4.0 .14 5000W
1.0 3.1 .11 7000W

Values in bold italics are not recommended; above power handling limits

Brahma 12
Qtc Box Size (L) Box Size (ft3) Power
0.5 170.5 6.01 400W
0.577 59.8 2.10 500W
0.707 25.9 .92 900W
0.8 17.6 .62 1300W
0.9 12.6 .45 2000W
1.0 9.6 .34 2800W

Values in bold italics are not recommended; above power handling limits

Brahma 15
Qtc Box Size (L) Box Size (ft3) Power
0.5 862.7 20.48 400W
0.577 204.5 7.26 500W
0.707 80.6 2.85 800W
0.8 53.4 1.89 1200W
0.9 37.9 1.34 1800W
1.0 28.6 1.01 2500W
On the 15", a .707 qtc only needs 800 watts, which is ideal.
