Purchased the 4 channel 1600 watt version. Ran it for a week just running my door speakers and worked flawlessly. Easy to install, easy to tune and sounded good on my door speakers.
Once I added a single 10" subwoofer, the amp would go into protection mode. Amp claims it is 2 ohm stable, but it is now. I was running a single 10 with dual 4 ohm voice coils and when you have the volume up and the bass hits, the amp shuts down.
Amp sounded good when it was running, but doesn’t last very long. Probably works great with subs in 4 ohm, but does not work in 2 ohms.
