GETTING SIGNAL TO THE Basspro 8
If your head unit has single or dual subwoofer outputs, use RCA patch cables to connect them to the line-level inputs
of the Basspro 8 harness. For single subwoofer outputs, use an RCA Y-adapter cable to connect to the Basspro 8
line-level inputs. If your head unit offers stereo subwoofer outputs, connect to the line-level inputs of the Basspro 8
harness using stereo RCA patch cables.
SPEAKER-LEVEL SIGNAL INPUTS
If your head unit only has speaker-level outputs, use the included speaker-level input adapters. Splice the gray and
gray/black wires into your vehicle’s front left speaker wires, and the green and green/black wires into your vehicle’s
front right speakers wires (using solder is recommended). Then plug each adapter in to the RCA inputs of the
Basspro 8 harness.
BASS LEVEL REMOTE
If you’re using a compatible JBL RBC remote bass level controller (sold separately at https://www.jbl.com), plug its
connector directly in the REMOTE input on the back panel.
