Reliable Performance

The S-Series amplifiers contain technology that was previously only available in Alpine's 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.

Reliable Performance

Small But Mighty

The S-Series amplifiers are designed to fit anywhere. The S-A55V 5-Channel model measures at 11.25” W x 8” H x 2.25” D and can be mounted under seats or behind panels. It proves to be the all-in-one solution for a multi-amp system, so you can enjoy big power output in a limited installation space.
