Item #: 39026
These subs are amazing! I first installed in a sealed enclosure at the exact specifications recommended (1.46 cub. ft) and powered with a kicker DX1000.1 amplifier. I wasn't satisfied with the sound at all. I swapped out to a Obcon labrinth style pored box and ohh boy! What a world of difference! Moves ALOT of air to say the least! Only down fall in my opinion is the attached lead wires. I would much rather have some nice binding posts on the speakers. Other than that these subs are built tough and are heavy as hell! 2 of them in the box weighs in at over 105 lbs!
