Mosconi ATOMO 1 Subwoofer Amplifier

Didn't expect this much output from something I could hold in one hand. The onboard low-pass filter let me dial in my sub without touching the head unit, and it stays clean even when I push the gain. Fits behind the dash panel with room to spare.

The autosense power-on is the feature I didn't know I needed until I wired it up — no remote turn-on lead, it just wakes up with the signal. For a mono amp this small it pushes my sub cleanly, and the selectable LP filter let me dial it in without extra gear.

Mounted this under the dash where there was basically no room, and it still pushes my sub cleanly. The high level input autosense means it wakes up with the factory radio without any extra remote wire.
