1x JL Audio 10TW1-4: 10-inch (250 mm) Subwoofer Driver 4 Ohm (10TW1-4)
JL Audio 10TW1-4
TW1 10-inch Subwoofer Driver (300 W, 4 Ω)
Built on JL Audio's patented thin-line subwoofer technology, the 10TW1 delivers a powerful combination of shallow mounting depth and excursion capability, while operating in insanely small enclosures (0.35 cu.ft. / 10 liters). This, combined with a special cast alloy frame design, makes the 10TW1 capable of operating in extremely tight spaces. These include under-seat installations in trucks, 2-seat sports cars and many other creative applications requiring a compact, low profile subwoofer design.
JL Audio's patented thin-line woofer technology compresses the architecture of the 10TW1 using a "concentric tube" structure built into the injection-molded cone body. This structure supports the voice coil and a full annular spider, while permitting the placement of a large motor structure further forward in the speaker than with conventional designs.
The 10TW1 also features a clever frame design that minimizes the frontal clearance required for the excursion of the driver. This is accomplished by recessing the suspension attachment surface, so that most of the forward excursion occurs within the frame's dimensions. Thanks to this feature, the 10TW1 requires only 0.87 inches (22 mm) of frontal clearance, even with its grille installed. This allows for more efficient use of space and increased enclosure volume within a given overall depth.
Even though the 10TW1 is optimized for an enclosure much smaller than any other JL Audio ten-inch subwoofer driver, it never sounds like a big woofer struggling in a tiny box...instead, it delivers all the rich, deep, controlled bass you have come to expect from a JL Audio subwoofer system.

1x JL Audio XDM300/1 XDM Series Monoblock Class-D Car/Marine Subwoofer Amplifier, 300 W (XDM300/1)
JL Audio XDM300/1 Monoblock Class D Car/Marine Subwoofer Amplifier, 300 W x 1 @ 2 Ω / 200 W x 1 @ 4 Ω - 14.4V
This little monoblock powerhouse employs JL Audio's high-speed NexD™ switching design to achieve unprecedented efficiency and amazing power output for its size. It is small enough to fit in most tight space applications, including small boats, pickups, motorcycles and UTV’s (in a weather-tight compartment).
Designed for car or boat installations, the XDM300/1 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 XDM300/1 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.

1x JL Audio HD-RLC:Amplifier Remote Level Control and Cable (HD-RLC)
JL Audio HD-RLC: Amplifier Remote Level Control and Cable
Remote Level Control for Select JL Audio Amplifiers
The HD-RLC remotely controls the Bass Level of the following JL Audio amplifiers:
HD-Series: All models
XD-Series: All models
MHD-Series: All models
M-Series: All models
When the HD-RLC is connected to the above amplifiers, it acts as an attenuator on the input gain of the amplifier and is used to adjust the overall level of the amplifier from the front of the vehicle.
The HD-RLC kit includes the rotary control with a black ABS knob, mounting hardware and one 18 ft. (5.5 m) cable.
A satin-finish aluminum knob can be purchased separately.
