The bass boost knob actually makes a difference on my single 10" sub, and I've got the remote control mounted up front for quick tweaks. Runs cool too, even after an hour of driving it hard at 2 ohms.

This little monoblock pushes my sub cleanly at 2 ohms and never once went into thermal protection during a two-hour drive. The bass boost knob actually does something useful instead of just muddying everything up.

Wired the remote subwoofer control knob up front and it's honestly the feature I use most, tweaking the low end from the driver's seat without reaching into the trunk. Even at 2 ohms this monoblock stays cool on long drives, which my old amp never managed.
