Alpine Mono Subwoofer Amplifier, 600-Watts @ 2-Ohm or 330-Watts @ 4-Ohm Impedance The S-Series amplifiers are designed to fit anywhere.  Measuring at 8”, these amplifiers can be mounted under seats or behind panels.  Though they sport a compact footprint on the outside, they produce impressive power on the inside. At 600 watts RMS, the S-A60M is a powerful partner to drive the versatile S-Series subwoofers. The S-Series amplifiers contain technology that was previously only available in our premium line up of amplifiers, the R- and X-Series models. The S-Series models are based on Alpine’s intelligent amplifier platform that ensures superior sound reproduction and precision imaging. With an improved heat sink, and protection circuit design that eliminates thermal shut-down, your music will keep playing no matter where your drive takes you.
