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.
POWER AND PROTECT LEDs
The back panel includes two LED indicators. When POWER is illuminated, the
Basspro 8 is turned on. When PROTECT is illuminated, the Basspro 8 has
entered protect mode due to overheating or over/under-voltage conditions.
SETTING THE GAIN, CROSSOVER, PHASE, AND
BASS BOOST
Adjusting the gain lets you match the input sensitivity of Basspro 8 with the
output of your receiver, and match the relative volume to the rest of the
speakers in your vehicle.
1. Start with gain control set to minimum, and the crossover control and
bass control rotated midway.
2. Choose music with substantial bass content and turn the volume control
on your receiver to ¾ of its total output.
3. Adjust the gain control clockwise, listening carefully to the bass output. If
you hear distortion, turn the gain control counterclockwise to decrease
the gain.
4. Switch the phase back and forth between 0 and 180 degrees to
determine which setting provides the most clean bass output.
5. Adjust the crossover control (between 60Hz and 200Hz) until the
Basspro 8 plays only low-frequency information – you should not hear
elements such as vocals coming from the woofer.
6. Adjust the Bass EQ control clockwise or counterclockwise between 0 and
9 dB to enhance the bass output to suit your taste.
