    SQ is class AB. Stop playing games! Welcome to the old school

    Posted by Brandon metalleg basshead burns on Jun 20, 2023

    This amp screams SQ wether it's out of mids or highs. Don't matter. It's sexy. It's pimpin purple. It's got sexy plexy under her skirt. Stop playing with these class D amps when it comes to your vocals. Nobody cares about how hard you can yell if you can understand what your saying. That's the relationship between class d vs class ab. Yes class D offers power. But where's the clarity? You'll hear instrumental pieces of your songs that you didn't even know what there. Certain chimes. certain computerized sounds they do in the studio that you just can't really hear as well thru dirty amps an crappy speakers. Quality speakers is another conversation for another day but quality sound starts here. You ain't buy it yet? Fine. More for me.

    Beyond impressed

    Posted by Desmond on Mar 02, 2023

    I can’t say enough good things about this amp, my mids, and my highs are perfectly matched with my subs (Kicker comp Q’s). My subs are being pushed by a J P 23. I highly recommend this amp. Thanks D4S

    Sound great..loud..

    Posted by Steve S on Feb 10, 2023

    First off the pictures don't do this amp justice. The purple is bright and looks great in the sunlight. Obviously the color isn't the only reason why we're here. The sound quality is just as great as the color. Coming from another brand with similar power levels to this one was night and day. My highs are much cleaner and brighter sounding. It plays my mids harder as well. It seems as if it has plenty of punch in reserve. I was so blown away by this amp I purchased a JP63 shortly afterwards to replace before mentioned same brand sub amplifier. Its well worth it, make sure you have the room though its a big amplifier but well worth it.

    Awesome Amp/Pure SQL

    Posted by John F on Nov 10, 2022

    For everyday listening, this AMP is amazing. Just enough power to bring my 6x9 and 6.5's alive. Truck rocks and my daily jams are pure joy. As usual D4S provides exceptional customer service and super fast shipping. Recommend.
