Kenwood Excelon X502-1 Class D Mono Subwoofer Power Amplifier
Brand: Kenwood
Kenwood's Excelon X502-1 mono subwoofer amplifier can send up to 500 watts RMS to your subwoofer, and it'll fit almost anywhere in your vehicle. A precise low-pass filter lets you optimize the sound for your sub, while the built-in bass boost lets you dial in just the right amount of thump. The subsonic filter removes ultra-low bass so that your amp and subs can operate more efficiently.

Class D technology ensures that this compact amp will run cool and perform reliably. Kenwood divided the amp's internal circuitry — analog, digital, and power supply — onto separate, non-overlapping circuit boards for improved overall sound quality. The X502-1 accepts input signals via RCA cables from an aftermarket receiver or by way of your vehicle's speaker wiring, so it'll work with almost any mobile audio system. If you do use the speaker-level inputs, the amp can sense the signal and turn itself on, so you won't need to run a separate remote turn-on lead to the receiver or fuse box.

The amplifier design is Class D, which uses digital switching power supplies. The result is the amplifier runs more efficiently, generating less heat than Class AB amps. The Class D design also allows the amplifier to be built on a small chassis, and installed where space is limited.
