Your Crutchfield WireGuide™

Wiring can be tricky, so we created this custom diagram to simplify your installation. Review it before you begin, and reach out to our Virginia‑based tech support team if you need help.

This is a wire-splicing guide, so RCA-type and other connectors are not covered. Check out this article for more information on connecting your receiver's wiring harness.
