JL Audio 500/1v2:

These settings are intended as a “baseline” for tuning your system. Depending on your vehicle and your preferences, some variation in the crossover and bass control settings may be necessary for optimum performance.

Bass EQ:

Generally not necessary in W7 applications (we recommend defeating it by switching the “Bass EQ” switch to “Off”). May be used with Remote Bass Control to provide some user controllable broad bass boost. When used in this manner, set “Q” to “1.1”, set “Center Freq.” to “45” Hz, “Boost” is defeated by connection of Remote Bass Control.

	Input Sensitivity Controls:
Infrasonic Filter:	Proper adjustment of these controls is critical!
	For virtually all aftermarket head units,
Turn “Off”for Sealed Enclosure.	set “Input Voltage” to “Low”.
Turn “On” for Ported Enclosure and	See “Input Sensitivity Setting Guide”
set the knob to “25” Hz.	on pg. 14 for precise setting instructions.

Dual Mono Speaker

Output Connections: Connect wire directly to “+” and “–”“Subwoofer Output” connections and to the W7.

Remote Bass Port: Permits connection of an optional remote bass boost controller (RBC-1), giving you control over the boost of the parametric EQ from the front of the vehicle. The RBC-1 controller is sold separately.

Amp Low-Pass Filter:

Set “Mode/Slope” switch to “24dB”. Set “Filter Freq. (Hz)” knob to “85”. Lower settings are likely to result in a poor transition between the upper response of the W7 and the lower response of the mid-bass speakers.

Ampli￿er Input: Connect RCA-type cables from the head unit (or processor) to these two jacks.

Use both jacks (with a Y-adapter if necessary).
