Decent for Price point.

Not too bad. SOunds clean on highs and mids. SOunds cleaner on lows though. ON highs I had the amp kinda running hot. Needs to be well ventilated . Will get very hot fast. Hadn't shut off on me but would seem to get muddy after a while and running hot. Reinstalled it in my neighbor's acura pushing a 4 ohm MTX 12 bridged at 4 ohms mono and installed in an open area and it sounds awesome!!!

No Complaints

Amateur running higher end Memphis components. Seems as clean as my antique Alpine, to louder than I listen. Not sure, but has to be more durable than the Soundstream Rubicon it replaces after 2-3 years. Easy tuning knobs seem ruined by needing an allen wrench to take off face plate for access. But set it and forget it I guess. Haven't quite matched it to a sub yet, so leaving it off doesn't seem to induce movement. Bottom line: nice looking, at least good enough for listening, and cheap.
