Customer Reviews (4.8 / 5 · 5 reviews)

Stella ★★★★★

The variable electronic crossover is dead simple to adjust and really cleaned up the sound from my old setup. I've got all four channels running and it stays cool even after an hour of driving it hard.

Claire ★★★★★

Speaker level inputs made hooking this up to my factory stereo a breeze, no adapters needed. The 4x100w at 4 ohms is plenty loud for my door speakers and the crossover is easy to dial in by ear. Install took me about an hour and it’s been dead quiet with zero engine noise since.

Andrew ★★★★★

The variable electronic crossover is dead easy to dial in, and the RCA inputs are clean enough to handle both my head unit and factory deck without any noise. It's been running two weeks straight in my truck and hasn't gotten more than warm to the touch, which is a relief for a Class D this size.
