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):				30,000			= New Capacitor Value in ∝F
	Desired crossover Frequency in Hz
Low-Pass(Subwoofer Crossover):				620			= New Inductor Value in mH
		Desired crossover Frequency in Hz
