is heat- and oil-resistant whenever
running wires through the engine
compartment. All wire-to-wire
connections should be soldered and
insulated with heat shrink tubing, or
connected through a high-quality
insulated crimp-on connector or
secure set-screw-type terminal
blocks. Never leave bare wire
exposed. Terminate wires with crimp-
or solder-on lug terminals whenever
appropriate.

*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
