Overview

An amplifier shouldn't take up too much space, especially in your car. This Class-D amplifier might just be what you're looking for. It combines a 1-Ohm stable circuit, installation flexibility and superior high-power output.

Features

Big Power, Small Size
Pioneer's new extra-efficient Class-D digital amplifiers mark a dramatic improvement in power output capability, yet are 50% smaller than the current GM-Series Class-AB amplifiers. That makes them more versatile in terms of installation as well as performance.

Improved Circuit Design
To prevent circuit shutdown, Pioneer's new digital amplifier circuit "Protection Control System" senses its internal temperature and automatically moderates input level accordingly. Stable, durable circuitry lessens the risk of high input power for the unit to achieve 1 Ohm connection. This design enhances the flexibility to connect multiple subwoofers to a system.
