C4 Corvettes equipped with the Delco-Bose sound system are unique in that not just any replacement speaker will work. These speakers must be amplified at the speaker - not the stereo. Most aftermarket speakers are not equipped with the amplifiers needed to produce sound from a Delco-Bose stereo. Note: This is a convertible amplifier, but it will work in coupes also.
If using in a 1990 you will have to use with part # 524009 harness.
Electrical components such as amplifiers are non-returnable parts.
Always refer to a factory service manual when diagnosing radio problems.You can damage electrical components if the proper procedures are not followed. Be sure you are replacing the correct part.
