Audio Dynamics ADS 1200.1 Class D Monoblock Subwoofer Amplifier. This isn't a cheap "store brand" amp—
Audio Dynamics is known for high-quality internal components and underrated power.
This was in a vehicle I recently sold. It was working when it was disconnected. I've decided to sell it, so to make sure it was still working, I ran power to it, and tested the output to the speaker jacks. I made a short video to confirm it has power and ease concern. I can email the video to anyone wanting to see it light up green & hear the audible click of the internal relay engaging. I also hooked it up to a multimeter to make sure the output jacks were sending a signal where the speakers would connect to and it was responding.
Specs:
Power: 1200 Watts RMS @ 1 Ohm (800W @ 2 Ohm)
Type: Monoblock (Dedicated Subwoofer Amp)
Features: Built-in clipping indicator, subsonic filter, and high-quality 4AWG power terminals.
Condition:
Bench Tested: Unit powers on perfectly with a solid green light.
Healthy: Internal protection relay clicks over immediately (no protect mode issues).
Output: Tested for signal response across speaker terminals; unit is reactive and ready to thump.
These retail for $425+. My price is fair for a high-performance amp that is confirmed working.
Terminals are clean with no stripped screws—ready for a secure 4AWG power connection."
