JBL Apex PA454
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.
