With its super efficient Class-BD circuit topology, the P500-1bd will drop some serious BASS! Due to its dedicated low frequency response, this amplifier is optimized for mid-bass speakers or subwoofers only. No need to worry because its 1-ohm capability will drive a pair of 4-ohm DVC subwoofers or quad-configuration of 2-ohm DVC subwoofers with ease.

    4.5 Star Rating Sam S From United States

    Pushed at 4ohm To a rockford P3 10" dual4 ohm sub in a 1.8 cubic foot box. Ifigured the sub would be under powered But compared To my last set up, which was a 10" typeR @ 2ohm getting 500 watts from an old Hifonic1206d 1200watt amp. That amp died so i bought This one and a p3. birth sheet power specs were damn near 30% higher then the CEA compliant specs which makes sense cause this amp powers the one p3 nicely. I have the gain up 75% and the amp dont break a sweat and from what i hear from a friend who owns at car audio shop and sells RF equipment, these punch series amps are heavy duty and unkillable. OCS offers this amp at a great price and its more powerful than the new model which cost like $50 more. Buy this amp for any sub you're trying to give a clean 250 watts@ 4ohm and any sub u Can wire lower than 4ohm 400-600watt rms subs.

    this amp is one hell of a good amp... I DID have 2 12 Boss Audio subs and this amp...and it pushed them with no problem.... 1 10" Kicker CVR would be a better candidate though.
