Speaker-Level Output Connection
(Use only when line-level output
is not available)
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.

*You may change the subwoofer satellite crossover frequency by using the
Inductor and Capacitor values calculated with the following formulas:
High-Pass (Satellite Crossover): = New Capacitor Value in µF
Low-Pass (Subwoofer Crossover): = New Inductor Value in mH
