About the JBL Apex PA454
That little thing's an amp?
That little thing's an amp?
You won't believe how much sound comes out of this tiny amp. JBL's Apex PA454 puts out four channels of 45 watts RMS from a chassis that's smaller than a shoe. It'll fit in almost any little nook or cranny on your UTV, motorcycle, or boat, bringing the joy of music to your outdoor fun.
Dedicated design and controls
The Apex PA454 is designed to power four standard 4-ohm speakers, and can't be bridged to run a sub, for example. Selectable high-pass filters let you tune the signals to match your speakers. The tough aluminum chassis and conformal-coated circuit boards protect the amp against the weather. The controls are protected behind an aluminum panel.
