A high-pass filter shapes the signal to fit your full-range speakers for their best-sounding output. You can also configure this amp for one-channel operation to power a subwoofer with up to 200 watts RMS. A low-pass filter and a bass boost EQ help dial in just the right amount of bass bump.

This amp can have two speakers connected to each of its 2 channels. It can power 4 speakers and could power both front and rear speakers in a vehicle.
