## Description

The Kenwood Excelon X502-1 Mono Subwoofer Amplifier transmits up to 500 watts of RMS to the subwoofer, and fits almost anywhere in your vehicle. Accurate low pass filter optimizes sub sound and built-in bass boost lets you dial the right amount of sound. Subsonic filters remove ultra-low bass and operate amplifier and sub more efficiently. With Class D technology, this compact amplifier is cool and guaranteed to work. Kenwood splits the internal circuitry (analog, digital, and power) of the amplifier into separate non-duplicate circuit boards to improve overall sound quality. The X502-1 works with almost any mobile audio system because it accepts input signal from aftermarket receiver via RCA cable. When using the speaker level input, the amplifier senses the signal and turns on itself so there is no need to run another remote-on lead in the receiver or fuse box. Product Features: Mono Subwoofer Amplifier 300 Watts RMS x 1 4 Ohm (500 Watts RMS x 1 2 Ohms) CTA-2006 compliant. Class D Amplifier Design Variable low pass filter (24dB/50-200Hz at octave) Bass Boost (0-18dB at 40Hz) Subsonic Filter (25Hz at 24dB per octave) Preamp and speaker level input Wiring and hardware are not included with the amplifier. 8 gauge power and ground lead recommended Fuse Rating: 30A x 2 8-7/16"W x 2-1/8"H x 5-15/16"D Package Includes: Mono Subwoofer Amplifier Two 30 Amp ATC fuses (installed) Terminal cover (installed) 8" Speaker Level Input Harness 4 x 5/8" Screws User Manual (English/French/Spanish)
