C4 BOSE WOES: Repairing & Replacing 84-96 Bose Speakers & Amps

lead shot

If you own a C-4 equipped with Bose sound system, you will eventually need Bose amplifier repair or replacement. Every Bose sound system equipped C-4 uses one amplifier per speaker. This is the weak link. Amplifier capacitors are filled with electrolytic fluid which ultimately leaks out onto the circuit board causing failure. If the leak is slow, the amplifier’s circuit board can be damaged beyond repair. Electrolytic fluid is acidic and will corrode anything it touches.

84-96 Door Outside Seal Strip Replacement

C4 Outside Seal Strip Replacement Lead Shot (1) (Medium)

Automotive door sealing technology has improved dramatically from the early days when rain water came in from all angles. By 1969 GM changed the outer seal strip that wipes the glass clear on those damp mornings to do a good job of keeping water out of the door. In turn it kept water off of the door internals and off the backside of the fiber door panels. By 1984 the door outside seal strip was an integral part of door glass sealing. The downside was they were the most exposed seal strips to date subjecting them to the effects of UV deterioration much quicker than previous year Corvettes. You can help keep them around longer with an application of rubber protectant to replace the rubber solvent compounds removed after each wash job. Products like Adams V.R.T. Vinyl Rubber and Tire Dressing from Corvette Central P/N 106824 will keep your outside seal strips looking good for many years. This dressing brings back that new look without that greasy oily slick look, you can also touch it without fear of it coming off on your hands or clothes.
