adire
ok, so people talk about the adire brahma alot, and how great it is. personally, i have never heard it, and most people up here (in canada) dont know about it either. My question is this... right now i have a jbl 300.1 amp, which i guess i could run 150 watts to each voice coil with of the brahma, but would that severly underpower that sub? I know that the ratings on the website say that the 12 inch brahma requires 400 watts in a .5 inch enclosure, but weather or not that is simply a minimum is beyond me. People also compare this sub to the w7, and if that is the case, then my amp would severly underpower the brahma and burn out the voice coils... right? i am a little confused about all this, and any input would be nice. on their website, they also say that their ratings are based on 1 ohm loads... i dont know if my amp is 1 ohm stable ( i doubt it though), and again, i dont know if i can run this sub with my amp if this is the case.

Box size also contributes to the amount of power needed and how well the sub performs. If your after alot of spl along with sound quality that amp won't do it. If your after good sound then that amp would do but I wouldn't recomend it. If you do decide to go with that amp make the box around 1.5 cuft sealed or do some research and make a ported box. Also be sure to set the lowpass filter around 80 htz and don't turn the gain up more than 5/8 up. Do you ever plan to upgrade amps? If so look for something around 800-1000 watts and that should have nice output and SQ.

Having too little power will not burn up your voice coils. That is just a myth. Its distortion from cranking the amp too high with too little power that burns up speakers.

You're absolutely right. Unfortunately, that happens A LOT. Get a small amp, then crank the snot out of it trying to get every last dB. Unfortunately, you can run up to 10, even 20% distortion before it's really audible at low frequencies, so by the time you clip the amp bad enough to hear a difference, you're already feeding a seriously bad signal into the subs.
