*You may change the subwoofer satellite crossover frequency by using the Inductor and Capacitor values calculated with the following formulas:

	30,000
High-Pass (Satellite Crossover):	= New Capacitor Value in ∝F

draws negligible current so a relatively small (18 or 20 gauge) wire may be used.

•Using the REM-OUT feature – The REM- IN/OUT terminal of the GTQ amplifier may be used to turn on other amplifiers when the GTQ amplifier is being turned on by the Common Sense circuitry in the speaker-level input. Simply connect the

head unit speaker-level outputs to the GTQ amplifier speaker-level inputs and connect the REM-IN/OUT terminal to the remote-in terminal of other amplifiers or signal processors. The GTQ amplifier will turn on the other amps or processors whenever the Common Sense circuitry turns on the GTQ amplifier.
