Kenwood X803-5 5-Channel Amplifier

The Kenwood X803-5 is a 5-channel car amplifier built around a Class D circuit design. It delivers up to 1600W max power and is certified for high-resolution audio. The unit includes a wired remote control for convenient level adjustments from the driver's seat.

Suits systems needing four speakers plus a subwoofer

This amplifier fits installations that require four full-range channels and a dedicated subwoofer channel in one chassis. It is not for buyers who want more than five channels of amplification or those building a system without a subwoofer.

Handles 75W x4 at 4Ω with 500W for the sub at 2Ω

The amp comfortably drives four speakers at 75W RMS each (4Ω) while powering a subwoofer with up to 500W RMS at 2Ω. Headroom drops when the subwoofer load rises to 4Ω, limiting sub output to 300W RMS.

Questions about this item

What head-unit output do I need to connect to the amplifier's speaker-level inputs?

The amplifier accepts speaker-level signals directly from a factory or aftermarket head unit, so no separate line-level converter is required.

Will the 75 W × 4 channels at 4 Ω integrate with my existing 4 Ω door speakers?

Yes, each front and rear channel delivers 75 W RMS into 4 Ω, matching typical 4 Ω component or coaxial speakers.

How can I verify the subwoofer channel is delivering 500 W RMS at 2 Ω after installation?

With a 2 Ω subwoofer load, the mono channel is rated for 500 W RMS; measure clean output with a multimeter or listen for distortion-free bass at high volume.
