Quick tips:
1. Please plug the power cord into the amp THEN the wall, plug the audio cables into amp THEN switch on.
Some customers may see some slight sparks flying when they plug the power supply into the amplifier, because they use it in wrong way, you need to connect the amp to the power supply first, then plug the power supply into the 110v AC outlet, don't worry about the sparks, because this is class d amplifier, the capacitors need to charge when the power in, it's normal and safe.

Worth every penny. Paired with Fosi BT20A PRO and polk audio speakers. Sounds amazing.

I hooked this into a jbl 160 with a failed plate amp that houses an 8" 4ohm svc subwoofer. This little beast can easily overdrive that woofer at 60%. Played for about 10 minutes in the garage and the unit was cold to the touch. Next I'm going to try two 12" dvc subs at 2 ohm. I have no doubts that it will be up to the task. Very impressed. Crazy how far amp technology has come since I was a kid. Only test now will be longevity. I'll try to update if anything changes.

This replaced a cumbersome plate amplifier and I lost nothing in performance
