That little thing's an amp?

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.
