JL Audio AP2004/BT – Compact 4-Channel Marine Amplifier with Bluetooth® Streaming
The JL Audio AP2004/BT is a compact 4-channel Class-D amplifier with integrated Bluetooth® audio designed for small boats, PWCs, and overland vehicles. It combines efficient full-range power, marine-rated durability, and simple wireless control in a small footprint that is easy to mount in tight spaces.
Compact Class-D Power with Bluetooth® Audio
The AP2004/BT uses efficient Class-D amplifier technology to provide clean power with lower current draw than traditional Class-AB designs. It is designed to run from a 9–16 VDC electrical system and is well suited for smaller boats, jet skis, and powersports/overland applications where available power and space are limited.
Rated at 40 watts x 4 into 4 ohms or 50 watts x 4 into 2 ohms (14.4 V, <1% THD), the amplifier can also be bridged to deliver 100 watts x 2 at 4 ohms. This provides enough output for full-range speakers and small subwoofer channels within a single, compact chassis.
- 4-channel Class-D design for efficient, full-range output with reduced battery load.
- Bluetooth® audio built-in, so a separate head unit is not required for basic systems.
- Rated continuous power of 40 W x 4 @ 4 Ω or 50 W x 4 @ 2 Ω; 100 W x 2 @ 4 Ω bridged.
- 20 Hz–20 kHz frequency response (+0, -1 dB) for full-range music reproduction.
- THD+N <1% at rated 4-ohm power with signal-to-noise ratio >70 dB (A-weighted, 1 W).
Bluetooth® Control and Marine-Ready Construction
The AP2004/BT pairs directly with a compatible smartphone or tablet for wireless audio streaming. An IPX7-rated wired remote is included and can be flush-mounted, surface-mounted, or bar-mounted, allowing you to control playback and volume from a convenient location on your boat or vehicle.
The amplifier chassis is built to IP67 water and dust standards (excluding cables) and is ignition protected, making it suitable for harsh marine environments and engine compartments when installed correctly. Its compact size allows flexible mounting options without taking up valuable storage or cockpit space.
- IP67-rated amplifier chassis for water and dust resistance in marine applications.
- Ignition protected design for safe installation in appropriate engine compartment locations.
- IPX7-rated wired remote with multiple mounting options (flush, surface, or bar).
- Operating temperature range from 4° to 149°F (-20° to 65°C) for real-world outdoor use.
- Very low standby current draw (<1 mA) and idle current consumption under 700–750 mA.
