Features

Compatibility: The OEA-4 (model C4NN03) is a non-electronic interface that allows an aftermarket high-power stereo to integrate into select 1994-up Nissan and Infiniti 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 two white and black rectangular Molex plugs. There are 5 additional wires coming from one of the white/black plugs and 2 wires from the other white/black plug that should be spliced to the receiver's wiring harness. The Molex plug ends are molded to match with the factory wiring harnesses. Crimp caps are provided for wire splices.
