Our take on the Kenwood Excelon X803-5 50W x 4 + 500W x 1 Car Amplifier

The Kenwood Excelon X803-5 is a five-channel Class D car amplifier that powers four speakers plus a subwoofer from one compact chassis. It is rated at 50W RMS per channel and 500W RMS for the subwoofer channel, and it is bridgeable for more power to the front stage. It suits drivers who want a single amp to run a full system without the size and heat of an AB-class design. Against five-channel rivals it stands out for its small footprint and clean Class D efficiency, though some owners find its tuning controls basic compared with DSP-equipped amps.

Questions and answers

How much power does the X803-5 put out?
It is rated at 50W RMS to each of four speaker channels and 500W RMS to the subwoofer channel. Bridging the speaker channels raises their output for front-stage speakers.
Can it run four speakers and a subwoofer at once?
Yes. That is its main purpose: four full-range channels plus a dedicated subwoofer channel in one amp.
Is it Class D or Class AB?
It is Class D, so it runs cooler and draws less current than a comparable AB-class amp.
Does it have a built-in DSP?
No. It has a low-pass filter for the subwoofer but no digital signal processing or detailed equalizer.
Can I use it in a boat?
No. Kenwood does not rate this amp for marine use, so it belongs in a car.
What is in the box?
The amplifier, mounting hardware and installation guide. Speaker and power wiring are not included.
