I recently purchased the HiFonics Brutus 1206D with a Crossfire BMF 12" subwoofer. In the beginning, we hooked it up and it didn't work. I took it to my audio specialist, which when he hooked it up in the shop, it worked. I hooked it up thereafter in my xterra, and it worked. I blew the 4-1 BMF 12, now I got the loaner 4-2 and blew it also. I recently switched to Kicker CompVR's and now im back to square 1 with the first problem I have. Everything is wired correctly, I have power goin' to the amp, but no sound from the sub. Help.

No. The LED should be off when the radio is off (amp turns off as well)
It sounds like you have constant 12volts applied to your remote turn on lead. The amplifier will have 3 connections for power:
1. 12volt constant 2. chassis ground 3. 12volt switched power - this wire should come directly from your head unit. It only sends 12 volts when the radio is on allowing to amp to power up only when the radio is on.
set the lp filter to about 100 to 125 (or lower if want seep boomy only) , put the bass eq no more than 75% but i would recommend no more than 50%, gain is to match the sound not to adjust power with so it is a user preference start all the way down and slowly go up till u hear distortion then turn it back down by about 10 - 15 %, phase shoild typically be at 0 degrees, subsonic depends on if you r using sealed or ported ported turn it all the way down then adjust as needed to get rid of the lower sounds you dont want (muddy sloppy sounding bass) if sealed turn it all the way up to at least 35 hz.
