Power your music
MB Quart's Reference Series RA1-150.2 two-channel amplifier provides 50 watts of power to a pair of speakers, so you can hear and feel your music clearly over road and engine noise. Designed to power high-quality aftermarket speakers, like their Reference Series speakers and components, this Class D amplifier utilizes MB Quart's unique Q-Stasis (Class SQ) circuitry to improve the accuracy and clarity of your music.
Versatile features
The amplifier's features include speaker-level inputs with signal-sensing amp turn-on, so it's ready to work in almost any system. 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.
