The MTX 8500s are WAY over rated, you people are not comparing apples to apples; high RMS ratings mean NOTHING. Id personally go with the brahma it will own the MTX T8500, T9500 etc... The MTX 9500 quoted by glass "sits on the same level as an Alpine Type R and can not compete with Adire Brahmas, Alpine Type Xs, REs, JL, etc..."
go wit the brahma over the mtx it is a way better sub than mtx but mtx does make good amps i think the subs suck and a amp to power the brahma would be a jbl 1200.1 of u can find one the hifonics is overrated and is only rms at 900 watts so it will prolly only do 700-800 true watts.
you wont need much more than 600-800 watts to get the brahma moving at full mechanical excursion, just because ratings are thermal, not mechanical as we all know...
i would be a little weary of applying 1200+ watts to a brahma, just because fo the reason it will reach its limits under 1000w
and if you look on adire's site, any power over 1000w rms is breaching their warranty is it would no longer be covered because of bottoming out, broken spider, tinsel leads, or anything caused by overexcursion
plus...have you heard a sub over its mechanical limits? sounds like crap and distorts reaaal bad on lower frequencies
i would reccomend a bp600.1 or BX750d for a brahma in almost any application..furthest i would go is a kx850.2 bridged to 4 ohms, since brahmas are all dual 2 ohm..even thats pushing it cuz kickers are underrated
i got a 15" brahma and was planning on useing a bx1000d? is this over kill will this hurt the sub.
Seince the Brahma is only 2Ohm SVC, the Hifonics Brutus BX1000D is rated at 700 RMS at 2ohm's. Should be fine, the voice coils can take the heat, just a matter of what volume and gain your running on the amp if your sub where to malfunction.
