CAUTION: QBASS ™ should only be used in systems with a strong subwoofer section. +12dB is a large amount of bass boost and may damage your speakers if abused. On the PCX 1250 amplifier, we offer tremendous control of your bass with QBASS™ . On the front end panel of your PCX 1250 you will find the QBASS™ level control.
Y ou will need to install an in-line fuse or circuit breaker in the power wire within 18" of the battery. This fuse or circuit breaker is to protect your vehicle from fire in case the power wire shorts to the vehicle body . If you are only using one amplifier, use the fuse rating indicated in this chart.
Before beginning, disconnect the negative (-) terminal of the battery prior to working on the positive (+) terminal to prevent a short to ground. This is important, unless you want to spend the rest of your life with a nickname like "Sparky," or "Smokey.
Once you have run both the power and ground wires, it's time to connect the cables to the amplifier. Cut off excess wire and, using wire strippers, strip the ends of the power and ground cables approximately 1/4 inch. Locate the Power Lock power and ground connector (supplied).
