    JP13 2018 Forester Black edition

    Posted by Aidan Calhoun on Oct 30, 2023

    What a unit an insane powerhouse. Paired with a sundown U12 at 1 omh this amp 9 o'clock gain will have every window and panel rattling. I did not expect so much power from a small amplifier. Definitely need to upgrade to an AGM or a second battery as it will drop two bolts with easy. Other then the fan sounding like a 2006 desktop I'm super happy!

    Awesome compact powerhouse

    Posted by Sergio Cuello on Aug 11, 2023

    I picked this amp up because of its smaller size compared to what was using. This amp doesn't disappoint. More than enough power to push my sub setup (Kicker L7) and stays cooler and with less amp draw.

    Mono power

    Posted by William Widener on Aug 06, 2023

    So i sold my JP8 to my brother. Upgraded to this so i can run it tobthe same subs at 4ohm. Plan on upgrading subs and electrical in order to run this at 1 ohm. In the meantime i am thouroughly impressed with the 4ohm power. And the subs sound super clean. Pushing NVX 10s (2) the 500 watt ones. And it sounds very very good and clean deep bass. Again D4S and mr price did awesome. Thanks Mr Price! I tell all my friends about Down4sound
