Description

KICKER PXA400.4 — Waterproof Four-Channel Amplifier (Used Closeout)

Two pre-owned amplifiers available, priced and sold individually. Purchase quantity one for one used PXA400.4; quantity two for both units. These are genuine used-closeout listings, not new retail units.

Compact Amplifier for Difficult Install Locations

The KICKER PXA400.4 delivers four independent full-range channels in a compact Class-D chassis. The manufacturer rates the amplifier enclosure IP66/IP67 for wet, dusty and demanding installation environments, making it suitable for properly designed motorcycle, UTV, golf-cart, hot-rod and other compact audio builds. The external power/ground couplers are not covered by the amplifier's IP rating.
