It's compact, attractive, and easy-to-use. And its circuitry is all solid state, including two high-powered ICs selected specifically for rugged mobile application. The AUTO STEREO POWER BOOSTER adds great performance, extra features, and increased power output to the stereo car radio or tape player. You'll hear music at a more enjoyable level and you'll probably hear some instrumentation you've missed before. It's easy to install the AUTO STEREO Power BOOSTER using the universal mounting bracket provided. For electrical power, use 12-volt, DC negative electrical ground only. Special Note: This Booster is designed to be connected to radios/tape players that incorporate BTL (Balanced Transformer-Less) or to common ground type. (Many Boosters can not be connected to BTL-type circuits without damage). However, it's vital that you identify input and output wires properly and that you don't interconnect "ground" or "negative-side" speaker wires. If you aren't sure how to connect the Booster to your existing units, we recommend strongly that you have your system installed by an experienced electronics service technician. WARNING: The speaker installation must have a total power capacity of at least 40 watts program material. For example, to use four 8-ohm speakers, each speaker must be rated for at least 10 watts program. The high power levels produced by this Power Booster can damage low-wattage speakers.
