    This is a awesome amplifier for the money.I have it hooked up 2 Skar EVL 8's @ 1-ohm.They sound delicious! Super clean and plenty of power in my wife's JeeP. Stock alt, only 1 battery, with 4 ga ofc power wire.I live the clip light on bass knob.

    This amp is a powerhouse! Small enough to fit in the small space in my single cab truck but packs serious power. Never even breaks a sweat powering my SA12 Great bang for your buck!

    This amplifier is pushing my 2 rockford fosgate 4 ohm subs and it is making them sound like a bomb hitting.

    This amp is small in size but packs a hell of a punch and the clipping light built in the remote is a great feature. Definitely recommend
