Wiring
See the section “Installation precautions” on page 3.
For safety, disconnect the negative terminal of the vehicle battery prior to wiring.
Use only high quality wires for reliable installation to minimize signal or power loss.
Make sure wires are not squeezed or damaged by sharp edges. Use rubber bushings for
penetrations.
Make sure all the cables are securely connected and bare wires are insulated with electric tape.
Reconnect the negative terminal of the vehicle only when all wire connections are correctly and
securely made.
Low-Level Input Wiring
The subwoofer offers you two wiring alternatives for audio input from your head unit. Low-level input wiring is
preferred for audio input. It provides an exceptional clean sound from the source unit.
Important!
Do not connect both the high-level and low-level inputs from your head unit to the subwoofer at
the same time.
To the RCA audio
outputs of head unit
L
R
• Using RCA cables, connect two RCA jacks (L/R) on the subwoofer to the RCA audio outputs on your head
unit. Make sure the left and right channels are correctly matched.
• To reduce the possibility of noise entering signal chain, use high-quality RCA cables for better insulation and
run the RCA cables away from large wire loops, electric fan and power wires.
High-Level Input Wiring
The subwoofer offers you two wiring alternatives for audio input from your head unit. Use high-level input wiring
for audio output only when your head unit does not have the RCA audio outputs for connection.
Important!
Do not connect both the high-level and low-level inputs from your head unit to the subwoofer at
the same time.
