Compatibility: The OEA-4 (model C4GM02) is a non-electronic interface that allows an aftermarket high-power stereo to integrate into select 1986-96 General Motors vehicles with Bose premium factory systems. Please check the Crutchfield Vehicle Selector for compatibility for your vehicle.
Adjustment Gain Controls: Four rotary gain controls (front left, front right, rear left, rear right) are located recessed inside the adapter chassis. There is a small flat-blade screwdriver attached to the adapter's case, and its use is recommended. The controls are very fragile and sensitive, and a slight adjustment will change volume dramatically.
Harnesses: The adapter's input wires are approximately 5-1/2" long with bare ends. These splice to the new receiver's speaker output wires. The adapter's output wires are approximately 11" long and terminate into a white rectangular Molex plug. There are 5 additional wires coming from the white plug that should be spliced to the receiver's wiring harness. The Molex plug end is molded to match with the factory wiring harness. Crimp caps are provided for wire splices.
