JL Audio AP300/1 Compact Marine Mono Subwoofer Amplifier

JL Audio's AP300/1 amplifiers are tiny powerhouses, small enough to fit in in tight spaces yet powerful enough to drive speakers with the power they need for the outdoor environment.

Power the moment with the ultracompact JL Audio AP amplifiers, available in monoblock, 4-channel with and without Bluetooth® technology, as well as 6 channel with staggered power — ideal for a system amplifier.

These Class-D amplifiers are IP67-rated (excluding cables) with tough cast-alloy water-resistant construction. The monoblock, 4-channel and 6-channel features built-in LCDs for manual control. For additional optimisation, pair with a Fusion® head unit with built-in DSP, and download the Fusion Audio smartphone app for selectable profiles. This enables the Easy Tune feature, which streamlines amplifier setup to ensure superior sound quality and system protection.

The 4 channel with Bluetooth pairs with your smartphone for seamless audio streaming and includes an IP67-rated wired remote that can be flush-, surface- or bar-mounted.
