JL Audio MBT Marine Bluetooth Audio Receiver, aptX HD

Overview

The JL Audio MBT is a weatherproof Bluetooth audio receiver family that adds wireless streaming to a boat or powersports sound system through line-level RCA outputs. Connection range is rated up to 35 ft (11 m), and audio bandwidth covers 20 Hz to 20 kHz (+/- 1 dB).

Both configurations are meant to feed an amplifier or a head unit with line-level/aux inputs, not to power speakers directly. Output level is 4V RMS, with operating voltage depending on version (10 to 16 VDC for the receiver-only unit, 8 to 16 VDC for the controller/receiver).

This is a solid fit for boats that already have an amp and speakers installed and just need a clean way to stream from a phone or tablet. The controller version also suits helms where physical volume and track buttons matter, especially when the streaming device stays stowed and dry.

Key features

• Bluetooth A2DP streaming with Qualcomm aptX-HD support and a rated connection range up to 35 ft (11 m).
• 20 Hz to 20 kHz frequency response (+/- 1 dB) for full-range music playback.
• Line-level RCA connections for amplifiers or aux/line inputs, with 4V RMS output level.
• Receiver-only configuration (MBT-RXv2): IPX7 water resistance rating, 10 to 16 VDC operation, one stereo RCA output, 1 A remote turn-on output, and a 2 A fuse value.
• Controller/receiver configuration (MBT-CRXv3): IP67 water resistance rating, 8 to 16 VDC operation, backlit helm control interface, and single-hole mounting with a threaded collar.
• MBT-CRXv3 adds two stereo zone outputs plus a dedicated subwoofer output (RCA) for multi-zone systems.

Variants

This product is offered in two configurations that share the same core job: getting Bluetooth audio into a line-level marine system.

The main differences are whether there is a dash controller, how many preamp outputs are available, and the water-resistance rating and operating voltage range.

• 010-03377-00 - Controller: No. MBT-RXv2 receiver-only module with one stereo RCA output and a 1 A remote turn-on output. Playback is controlled from the paired streaming device.
• 010-03378-00 - Controller: Yes. MBT-CRXv3 controller/receiver with backlit controls, two stereo zone outputs, and a subwoofer output (RCA). It keeps volume and track control at the helm while the streaming device stays out of the way.

Installation and setup

For the receiver-only MBT-RXv2, mount the module in a protected location close to the amplifier or the input you are feeding, then connect 10 to 16 VDC power and the RCA output to a line-level input. The remote output can be used to trigger an amplifier turn-on lead when the system needs a switched signal.

For the MBT-CRXv3, the control face installs through a single cutout and clamps using a threaded collar. An adaptor plate is included for front-mount installs, thicker panels, or situations where rear access is limited. Route wiring away from sharp edges and moving parts, then secure it so it cannot chafe under vibration.

Compatibility and fit

These units are line-level sources and require an amplifier, powered speakers with RCA inputs, or a stereo/head unit with an auxiliary or line-level input. They are not intended to drive loudspeakers directly.

Bluetooth range is rated up to 35 ft (11 m) and can drop when the receiver is buried behind metal, wiring looms, or closed compartments. On smaller boats, placing the unit closer to the cockpit or helm area often helps keep the connection steady.

Care and mounting environment

The housings are water-resistant for outdoor marine use, but they should not be mounted where they can sit submerged for long periods or take direct high-pressure spray. Keep connectors supported, keep wiring runs tidy, and avoid high-heat locations like engine compartments.

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.
