PROP 65 WARNING
- Connects an aftermarket stereo to the factory radio harnesses
- Not compatible with factory amplified systems
- Direct Connection to the factory harness without cutting any wires
- Manufactured with factory quality wire and connectors
- Standard color coded wires for an easier installation
Some older GM vehicles have a factory amplifier which the factory antenna and speaker harness runs to. The GMK2B bypasses the factory amp and allows one to install an aftermarket stereo without requiring you to run new speaker wire to every speaker in the car.
