Frequently Asked Questions - 70-6502 Metra

Which vehicles is the Metra 70-6502 compatible with?

The 70-6502 is designed for select vehicles, including the 2003-2006 Jeep Wrangler with factory subwoofer. For full compatibility, refer to your vehicle's wiring or use Crutchfield's fit guide.

How difficult is it to install this wiring adaptor?

Installation requires basic tools: a wire stripper and crimp caps. You'll match wires by function (not color) and crimp connections. The process is straightforward for someone comfortable with car audio installation.

What do the wire colors on the adaptor mean?

Colors correspond to functions: Yellow (constant 12V), Red (switched 12V), Black (ground), Orange (illumination), White/Gray/Green/Violet for speakers (positive/negative), Blue (power antenna/amp turn-on). Always match by function, not color.

Do I need any additional parts for installation?

You may need a wiring harness adapter for your specific vehicle if not already included. The 70-6502 is usually a direct plug-in to the factory harness after crimping to your aftermarket receiver.

How do I know if this adaptor fits my car?

Check your vehicle's year, make, and model against Metra's compatibility list. For assistance, contact Crutchfield at 1-888-955-6000 or use their online vehicle selector.

What is the best way to crimp the wires?

Strip 1/2 inch of insulation, twist wires together, insert into a crimp cap, and squeeze the middle of the cap with a crimp tool until tight. Ensure a secure connection to avoid shorts.

What should I do if I have no sound after installation?

Verify all speaker wire connections are secure and match the receiver's outputs. Check that the receiver is powered (constant and switched 12V). Also ensure the antenna/amp turn-on wire is correctly connected if applicable.

Why isn't my receiver's illumination working?

The illumination wire (Orange) must be connected to the vehicle's illumination circuit. If your receiver lacks a dimmer wire, tape off the Orange wire. Some vehicles require a separate adapter.

Does this adaptor support power antennas or amplifiers?

Yes, the Blue wire provides 12V output for power antennas or amplifier turn-on. Connect it to the corresponding wire on your receiver and the vehicle's antenna or amp.

Is there a warranty for the Metra 70-6502?

Metra offers a limited lifetime warranty. Retain your receipt. For defects or replacements, contact Metra or your point of purchase, such as Crutchfield.
