Features

Your Optimus 2 x 50-Watt Trunk Mount Amplifier is designed to give added punch and power to your automobile's existing autosound system. The amplifier produces up to 50 watts per channel of clean, powerful sound at all audio frequencies with minimum distortion.

The amplifier's features include:

Full MOSFET Power Supply - produces enough power to supply the main amplifier and has a considerable amount of reserve power for peak "high demand" situations.

High or Low-Level Input Signal - accepts either high-level (speaker) or

Compatiblelow-level (pre-amplifier) input signals to match your autosound system's output for the best performance.

Input Level Control - lets you adjust the level (high or low) of audio signals that enter the amplifier.

Thermal Overload Protection - automatically shuts down the amplifier when it overheats or when its load or DC power output is shorted.

14k Gold-Plated Speaker Terminals - have high conductivity and minimum impedance.

WARNING: If you live in a high temperature area, we recommend you install cooling fans on the amplifier to provide a better operating temperature environment. Contact your local Radio Shack store for a suitable cooling fan.

If the connectors on your vehicle or automobile's autosound system are not compatible with the amplifier's connectors, contact your local Radio Shack store. Radio Shack stores sell adapter harnesses for many vehicles.
