C4 Corvette Bose Radio Rear Speaker Amplifier

This part is a new, reproduction for a C4 Bose Radio Rear Speaker Amplifier, which can be installed in any of the following Corvette models:

If your C4's Bose system sounds thin, flat, or like it's just going through the motions, the amplifiers are almost certainly the culprit. The factory Bose system in 1990–1996 Corvettes integrates the amplifier directly into each speaker housing, and over time those amps degrade, robbing your system of the punch and clarity Bose was known for.

This reproduction rear speaker amplifier brings it all back. Built using OE-spec components, it restores factory power output and sound quality without any guesswork or custom wiring. Replacement is straightforward: remove the factory speaker housing, unscrew the old amp, and bolt the new one in. That's it.

Key Feature

• OE-spec components: Matched to factory power ratings for correct output and sound signature
• Bolt-in fitment: Direct replacement, no wiring modifications required
• New reproduction unit: Not a remanufactured or refurbished core
• Restores factory Bose performance: Addresses the most common cause of weak or distorted sound in C4 systems
