Our Product Research Team

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team — they open the box, verify contents, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.

Features

Compatibility: The OEA-4 (model C4HA02) is a non-electronic interface that allows an aftermarket high-power stereo to integrate into select 1987-95 Honda and Acura 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.

Scosche CHA02 Factory Integration Adapter

Crutchfield Customer Review (What's this?)
 
This product was great. My brother has a 91 Acura, and I bought an aftermarket head unit to put in it, and this integration adapter worked perfectly. I knew that he had the bose sound system, but this was the perfect fix.
