This bundle includes a JL Audio XDM600/1 XDM Series Monoblock Class-D Car/Marine Subwoofer Amplifier, 600 W, and a JL Audio SBX-J-JL4DDRV/12TW3-4: Driver Side - 4 Ω Stealthbox for 2018-Up Jeep Wrangler Unlimited.
1x JL Audio XDM600/1 XDM Series Monoblock Class-D Car/Marine Subwoofer Amplifier, 600 W (XDM600/1)
JL Audio XDM600/1 Monoblock Class D Car/Marine Subwoofer Amplifier, 600 W x 1 @ 2 Ω / 400 W x 1 @ 4 Ω - 14.4V
This potent monoblock amplifier employs JL Audio's high-speed NexD™ switching design to achieve unprecedented efficiency and amazing power output from a very compact chassis. Don't let its small size fool you, though... the XDM/600/1 generates serious subwoofer power, delivering a full 600 W of continuous power into a 2 ohm load (14.4V, 1% THD).
Designed for car or boat installations, the XDM600/1 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.
Targeted specifically for subwoofer applications, the XDM600/1 includes a variable slope low-pass filter with continuously variable cutoff frequency selection from 50-500 Hz. With the addition of an optional HD-RLC or MHD-RLC (water-resistant) remote level controller (each sold separately), the amplifier's level can be adjusted directly from the driver's seat or captain’s chair.
Finished in a sleek, black powder-coat, all controls are protected beneath a gasketed, removable top cover for easy access.
