JL Audio AP Marine Amplifiers, Class D, 9-16VDC, IP67

Overview

The JL Audio AP amplifier series is a compact line of marine amplifiers for adding speaker or subwoofer power on a 12 V boat audio system. The range covers a monoblock subwoofer amplifier, 4-channel models with and without Bluetooth, and a 6-channel model with staggered power for more involved speaker and subwoofer layouts.

All models use Class D amplification, operate from 9-16 VDC and have an IP67-rated amplifier body, excluding cables. That makes the series a practical fit for consoles, storage lockers, helm compartments and other protected boat locations where spray, salt air, vibration and tight mounting space are part of the installation.

The non-Bluetooth AP300/1, AP300/4 and AP600/6 models include a built-in LCD display for manual control and can work with Fusion Audio app setup features when paired with a compatible Fusion head unit with built-in DSP. The Bluetooth AP200/4BT adds direct smartphone audio streaming, an IP67-rated wired remote and AUX input source selection.

Key features

• Marine amplifier range with 1-channel, 4-channel and 6-channel configurations for subwoofer, speaker and mixed system layouts.
• Class D amplification keeps the chassis compact while supporting RMS power ratings from 200 watts to 600 watts, depending on the model.
• 9-16 VDC operating range fits common 12 V marine electrical systems.
• IP67-rated amplifier body, excluding cables, for installations exposed to moisture, spray and dusty storage areas.
• Ignition-protected construction adds safety for marine and powersports installations where fuel vapors may be present.
• Protection circuits cover input under or over voltage, over temperature and output short circuit conditions.
• Built-in LCD control is included on the AP300/1, AP300/4 and AP600/6 models for setup without relying only on hidden switches.
• Bluetooth model includes a wired remote with IP67 rating and source selection for Bluetooth or AUX input.

Variants

The JL Audio AP amplifier series is offered in four configurations so the amplifier can match the number of speakers, subwoofers and zones in the boat audio system.

The variants differ by channel count, Bluetooth availability, RMS power layout, chassis size and included control hardware. All four models use Class D amplification, operate from 9-16 VDC and have an IP67 rating for the amplifier body.

• AP300/1: 1 channel, Bluetooth: No. This monoblock version is for subwoofer duty, with 200 watts x 1 at 4 ohms or 300 watts x 1 at 2 ohms.
• AP300/4: 4 channels, Bluetooth: No. This model works for four speaker channels or a bridged 2-channel layout, with 50 watts x 4 at 4 ohms or 150 watts x 2 when bridged at 4 ohms.
• AP600/6: 6 channels, Bluetooth: No. This stepped-power model supports larger speaker layouts and mixed speaker plus subwoofer systems, with channels 5 and 6 carrying more power than channels 1 through 4.
• AP200/4BT: 4 channels, Bluetooth: yes. This version adds direct Bluetooth audio streaming and includes a wired remote for source and control access away from the amplifier location.

Installation and setup

The compact housings help when mounting space is limited behind the helm, inside a console or near an existing stereo system. The AP300/1 and AP300/4 measure 1.85 in x 10.43 in x 4.90 in, the AP600/6 measures 1.85 in x 11.81 in x 5.90 in, and the AP200/4BT measures 1.85 in x 7.28 in x 4.90 in.

Plan power wiring, fuse protection and cable routing before mounting the amplifier. The AP300/1, AP300/4 and AP200/4BT use a 35 A fuse rating, while the AP600/6 uses a 70 A fuse rating. Keep signal cables and power cables routed cleanly to reduce noise and make future service easier.

System integration

The RCA input range is switchable between 200 mV-2 VRMS for low-level input and 800 mV-8 VRMS for high-level input, which gives the installer flexibility when matching the amplifier to a marine stereo or source unit. The AP300/1, AP300/4 and AP600/6 include variable crossover control from 20-500 Hz, depending on the channel layout, and all models include bass boost.

The AP200/4BT is useful for small boats, tenders and simple cockpit audio systems where direct phone streaming is useful and a full stereo head unit may not be needed. For more integrated systems with Fusion DSP setup, the AP300/1, AP300/4 and AP600/6 are the better fit within this range.

Use cases on board

The AP300/1 suits a dedicated marine subwoofer installation. The AP300/4 fits a straightforward cockpit or cabin speaker system, while the AP600/6 works for boats that need more channels or a speaker and subwoofer combination from one amplifier chassis.

Boaters building a clean audio system in limited space, replacing an aging amplifier or adding power to a new set of marine speakers will get the most value from this series when the channel count and power layout are matched carefully to the speakers, impedance and wiring plan.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
