[QUOTE="DanWiggins, post: 2142096, member: 544847"] That is 5 cubic feet for the pair, tuned to 36 Hz? Pretty peaky box... Try blocking one of the Aeroports to drop the tuning frequency to 30 Hz - I think he'll like the sound better and it'll still have plenty of port area. For the power, that's a LOT of power - set the gains correctly (no clipping - match the amp gain to the head deck please!), set the subsonic filter at 30 Hz. But most importantly get the gains right - don't just eyeball it or set it by ear. If it were me, I'd plug one port, and get Brahma D2s, wire the voice coils in series, and parallel the two drivers, giving each driver ~550W. You'll be within 1.7 dB of the full 1100W per driver (thermal compression eating up the other 1.3 dB), it'll sound as loud to the ear, and will be a lot easier on your alternator, amplifier, and drivers.
