About the Kenwood Excelon XM502-1
Big bass out of this tiny all-weather amp
Big bass out of this tiny all-weather amp
Any basshead will tell you that big power is key to great sound, but sometimes you just don't have much space in your boat or off-road vehicle for a big amp. Kenwood's Excelon XM502-1 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. An optional wired remote lets you control your sub's level from the driver's seat.
Convenient weather-proof technology
Conformal coating protects the internal circuits from water and dirt, so the show will always go on, even through the roughest conditions on road, trail, or waterway. Class D technology ensures that this compact amp will run cool and perform reliably. The amp accepts input signals from a receiver's RCA outputs or speaker wiring, so it'll work with almost any 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.
