    Partially my fault for not reading carefully, this amp is rated 1600 watts max. Way underpowered for my setup and kept shutting down.

    Great Mono Amp

    Very straightforward amp, does exactly what it needs to. I wish it had more options for tuning like subsonic filtering but for the price, it’s great.

    Driving two 10inch Rockford fosgate R2 DVC 4ohm down to one ohm and OMG with the gain set at maybe 5 percent it is driving them hard and clean amp doesn't even feel warm. Came with a super easy way to run if your stereo don't have RCA output!
