Very versatile amp, clean power.
Very versatile amplifier. I'm running my front speakers off my head units amp, SA-69s on channel 1&2 and two Infinity 10.1 4ohms wired parallel for a two ohm load bridging channels 3&4 for 1000rms to them. It sounds excellent! A 200amp fuse is recommend for this little amplifier. It's capable of 2000rms total, depending on how you wire it. Make sure your electrical system is up to it.

Clipping
This amplifier has A LOT OF POWER but I ran into issues with the rca ports which would cause my amplifier to clip than go into protect mode. I know this amplifier has a lot of potential, i just got the short end of the stick
