Customer Reviews (4.6 / 5 · 5 reviews)

George ★★★★★

Ran my front stage off this with the HP filters set around 80Hz and it's dead quiet between tracks, no hiss at all. The remote subwoofer control is a nice touch since I can tweak the bass from the driver's seat instead of pulling over. Two months in and it hasn't even gotten warm.

Sebastian ★★★★★

Wired this to a pair of 2Ω components and it runs dead stable without cutting out, which my old amp couldn't manage. The HP and LP filters made dialing in the front stage way easier than fiddling with a separate crossover. Bass boost is a bit much at full tilt, but backed off it's perfect.

Elizabeth ★★★★★

The bass boost on this thing actually does something useful instead of just muddying everything, and the remote sub control is handy since I can tweak it from the driver's seat. Running it at 2 ohms stereo and it stays cool even after an hour of loud play.
