Automotive 4 Channel Amplifiers

MX-Series 4-Channel Class-D Marine-Grade Amplifier, 70-Watts x 4ch @ 2-Ohm or 50-Watts x 4ch @ 4-Ohm Engineered specifically for powersports applications, the 4-channel MX280/4 amplifier employs JL's high-speed NexD™ switching design to deliver plenty of clean power, without straining charging systems. Its tiny, cast aluminum chassis is highly resistant to corrosion, with an IPX7 water-resistance rating, making it perfect for motorcycles, ATV’s or other utility vehicles. Generating a solid 50W x 4 into 4 ohms (14.4V, 1% THD), the MX280/4 is fully bridgeable, so it can be used as a 3-channel amplifier, or as a 2-channel amplifier producing a potent 140W x 2 into 4 ohms. Other features include independent front and rear crossovers with selectable full-range, high-pass or low-pass filter controls and a dual-range input section that accepts a wide range of input voltage levels, from line-level all the way to high-power speaker level signals. This amplifier features a black powder-coated finish, a gasketed cover for the controls and stainless steel hardware for durability.

Alpine 75-Watts RMS x 4-Channel Marine-Grade Head-Unit Power-Pack Amplifier The KTA-F30W is perfect for when you want to boost your sound system but don’t have the space for a large amplifier. It is compatible with an aftermarket or factory head unit and adds up to 4 times the power over the head unit's original built-in power. The KTA-30FW features Alpine’s exclusive Dynamic Peak Power (DPP) technology which uses a new dynamic power supply design that delivers bursts of power during rigorous musical passages. When the amplifier senses that more power is required, the power supply quickly increases the internal gain level, effectively doubling the power for a significant increase in dynamic range at high music volumes. The KTA-30FW is ready for your adventures. It is weather resistant, rated at IP66 for protection again dust ingress and high-pressure water spray. The KTA-30FW features a rugged chassis and high-quality waterproof connector so it can be used in installations where it will be exposed to the elements, like side-by-sides, boats, open- top vehicles. and motorcycles. The KTA-30FW measures just 9-3/16" (W) × 1-5/8" (H) x 3-3/4" (D), so its small footprint lets it fit where most amplifiers won't. The KTA-30FW can be tucked away under the dash or in the glove compartment, installed under the dash of a side-by-side, placed in the saddlebag of a motorcycle, or used in other places where space is an issue.

XDM-Series Four-Channel Class-D Marine-Grade Amplifier, 100-Watts x Four-Channels @ 2-Ohm or 75-Watts x 4-Channels @ Four-Ohm The ultra-compact XDM400/4 packs a serious full-range punch, generating a whopping 100-watts to each of its four channels into 2-ohms (14.4V, 1% THD). The technology that makes this much power possible in such a compact chassis is our advanced NexD high-speed switching design, which permits full bandwidth Class-D operation with extremely low distortion and remarkable efficiency. Suitable for car or boat installations, the XDM400/4 is built with marine-grade materials and features an exclusive, dual-mode input filter for noise-free performance in boats or cars. Automatic turn-on capability (via signal sensing or DC-offset sensing) is also onboard for easy factory system upgrades. Combine the XDM400/4 with our XDM600/1 monoblock to build a stunning 1000W amplification system to power four satellites and a subwoofer... and fit the whole thing under a seat or deck. Or, use the XDM400/4 by itself to power two satellites, plus a subwoofer.  The XDM400/4 includes a 12dB / octave filter for each channel bank, which can be configured as a low-pass or high-pass filter and offers continuously variable cutoff frequency selection from 50-500Hz. With the addition of an optional HD-RLC or MHD-RLC (water-resistant) remote level controller (each sold separately), you have the ability to adjust the level of all amplifier channels or just the rear channels directly from the driver's seat or cockpit. Finished in a sleek, black powder-coat, all controls are protected beneath a gasketed, removable top cover for easy access.
