12-inch 400 W RMS component subwoofer

The Kenwood Excelon XR-W1204 is a 12-inch component subwoofer rated at 400 watts RMS and 2000 watts peak power handling. It presents a 4-ohm impedance and uses an oversized polypropylene cone with a rubber surround mounted in a black steel basket. The driver targets car audio enthusiasts who want deep, controlled bass from a single high-output woofer in a custom enclosure.

Frequency response limited to 32–300 Hz

The usable bandwidth spans 32 Hz to 300 Hz, so the subwoofer reproduces low bass but does not extend into midrange frequencies. Sensitivity is 83 dB at 1 watt and 1 metre, meaning it requires adequate amplifier power to reach high output levels. The 4-ohm load suits many mono amplifiers, but the narrow bandwidth demands a proper crossover to prevent distortion above 300 Hz.

Straightforward install with 8 AWG push terminals

The woofer frame measures 12-13/16 inches square with an 11-inch cutout diameter and a mounting depth of 5-5/8 inches. Included mounting screws and a cushion simplify the basic mechanical fit. Dual ventilation and a stress-free damper aid thermal management, yet the 15.2 lb weight and deep basket can make placement difficult in tight enclosures, and the push terminals accept only up to 8 AWG wire.

Questions about this item

Should I choose the 4-ohm version or is there a 2-ohm option for this subwoofer?

The XR-W1204 is offered only in a 4-ohm configuration, so there is no 2-ohm variant to select from.

What does the 400 W RMS rating mean when the subwoofer is installed in my car?

It means the woofer can handle 400 watts of continuous power without thermal damage, delivering deep bass down to 32 Hz at 83 dB sensitivity.

What amplifier wiring does the 4-ohm impedance and 8 AWG push terminals require?

Wire a single 4-ohm load to an amplifier stable at 4 ohms; the push terminals accept up to 8 AWG speaker cable for a secure, low-resistance connection.
