Installation & System Requirements

Requires a suitable external amplifier, correctly fused power installation and speaker wiring. Isolate the front and rear acoustic spaces and follow JL Audio mounting and airspace guidance; an open, leaking mounting location is not a proper infinite baffle. Check depth, cutout, clearances and load compatibility. This version is not illuminated.
