OSD Audio SMP200 Class D Digital Subwoofer Amplifier Rated 200W Max

It's a simple connect and play could not be any more simple. I hooked it up to a 10'' JBL Subwoofer and i am happy.

I used this amp on a new construction surround system. Very happy with the sound. I used the OSD 10 inch subwoofer.

This worked well for the last 16 months but now it goes crazy at random times making the speaker sound-off with a very loud low frequency blast of sound. It does the in the middle of the night, but never when its in use.

I like the internal power supply and the controls on the front. The auto on and off trigger works well. I have not tested it as a speaker amp, just a sub amp. I really have just one complaint. When in stand bye mode the LED changes from green (active) to red (stand bye). The LED is so bright, it is like a red laser pointer in the room. At night it makes the entire room glow. I will end up putting some electrical tape over it, but you can see from my photo with my finger completely covering the LED how it still glows red. I wish there was a way to disable it.

Purchased to replace a failed SDA-200 subwoofer amplifier and this failed after a few months.
