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 properly insulated.
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 signal input from your source unit (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 source unit to the subwoofer at
the same time.
To the RCA audio
outputs of head unit
LR
• Using RCA cables (not included), connect two RCA jacks (LOW INPUT) 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 cable loops, electric fan and power cables.
High-Level Input Wiring
The subwoofer offers you two wiring alternatives for audio signal input from your source unit (head unit). Use
high-level input wiring for audio input from the source unit only when RCA audio outputs are not present on
the source unit.
Important! Do not connect both the high-level and low-level inputs from your source unit to the subwoofer at
the same time.
