Alexander J. ★★★★★

The adjustable crossover on this amp made tuning my front stage and rear fill super easy. It pushes my door speakers cleanly without any distortion, and runs surprisingly cool even after a long drive.

Elizabeth ★★★★★

Ran it bridged to my front stage and the active crossover made dialing in the frequencies a breeze. The black anodized heatsink stays cool even after an hour of hard driving.

Chloe ★★★★★

Installed this in my truck and the 4-channel class AB circuit really brought my speakers to life, even at low volume. The built-in crossover made tuning the system a breeze without needing extra gear.
