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. Adjust the level contro[...]

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. If you are using more than one amplifie[...]

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." Reconnect the negative terminal only after all connections have been made.[...]

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). With a small flat bladed screw driver , loosen the screws before a[...]

The Advanced Instrumentation Input has trickled down from the $15,000 Precision Power 2500F1 . This circuit completely isolates the chassis ground from the audio circuit of the amplifier and reduces noise radiated into your signal cables by up to 40dB. This is equivalent to a noise reduction of approximately one hundred times what the noise level w[...]

The following is a basic formula to be used as a guide to determine current draw . A50% amplifier efficiency rating is used as an average. Your new P C X ™ a m p l i f i e r is more efficient than most other amplifiers. This formula is to be used as a guideline. Using wire of a larger gauge can only improve the current transfer of your system. Do[...]
