Kenwood eXcelon X803-5 1600-Watt 5-Channel Class D Car Amplifier

The Kenwood eXcelon X803-5 is a compact 5-channel Class D amplifier built for buyers who want to power a full speaker system and subwoofer from one chassis without giving up installation flexibility. Its smaller eXcelon chassis makes it easier to fit in tighter vehicle spaces while still delivering clean output for front and rear speakers plus dedicated subwoofer power.

This amplifier is rated at 50 watts RMS x 4 plus 300 watts RMS x 1 at 4 ohms, 75 watts RMS x 4 plus 500 watts RMS x 1 at 2 ohms, and 150 watts RMS x 2 bridged plus 300 watts RMS x 1 at 4 ohms, with a 1600-watt max power rating. Kenwood also equips it with variable high-pass and low-pass filters, bass boost, speaker-level inputs, a wired remote, and High-Resolution Audio certification, making it a strong fit for clean all-in-one system builds.
