Kenwood Excelon

The Kenwood Excelon X501-1 mono amplifier can dish out up to 500 watts RMS to your sub, and it'll fit almost anywhere in your vehicle. A precise low-pass filter lets you optimize the sound for your vehicle and sub, while the built-in bass boost lets you dial in just the right amount of thump. And Kenwood protects this little powerhouse with a 2-year warranty. This amplifier's Class-D design allows Kenwood to pack maximum power into its compact chassis, and to ensure that it will run cool and perform reliably. The X501-1 accepts input signals from the preamp outputs on an aftermarket receiver or from your vehicle's speaker wires, so it will 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.
