Dx10 Spl

[JPHUNT]

I'M RUNNING 2 DX10'S IN A SEALED BOX OF .66FT^3 EA + ACOUSTIC STUFFING TO COMPENSATE FOR DRIVER VOLUME LOSS
POWERED BY A FOSGATE 600a4 BRIDGED TO 300w RMS EA
THESE ARE IN A GMC STANDARD CAB K2500
MY PROBLEM IS I CAN ONLY REACH 122db, WHICH IS WELL UNDER WHAT I EXPECTED, THE BASS ALPINES I RAN PREVIOUSLY COULD PEG THE 126db METER
I UNDERSTAND THE LIMITED AIR-SPACE OF A PICKUP AFFECTS THE F, BUT I THINK I SHOULD BE ABLE TO ACHIEVE MORE SPL.

I have an extended cab f150 and the same amp. I switched over to a 400a4 amplifier and actually attained a louder cleaner sound. It has seemed strange to me, but I don't think the 600a4 makes the best of sub amplifiers. Rockford Fosgate themselves recommend the Power series for operating subwoofers. I always thought that was for the extra money.
