Additionally, several times during the winter I got very loud "blats" which sounded like feedback loops through the stereo during rainy or damp weather. I would shut the stereo off, and the problem would go away after the weather and car dried out some. The blats would not cut off when the stereo was turned off, but would fade out. I suspect this was the coil and caps in the amp discharging.
Useful information about the workings, and particularly the wiring/pinouts for these 460 units is scant, and what is available is often incorrect. Troubleshooting without knowing what does what is darn near impossible.
Anyway, enough old memories, you seem to be the guru re: the mach 460 audio system. My questions are simple and concise. The Mach 460 in my 2003 GT convertible is completely stock so there are no compatability issues in the mix.
However, like so many others about 3 weeks ago my woofers stopped producing any sound. All 4 tweeters (mirror mounts in front and top 2 drivers in back) still work, just no bottom anywhere. It is worthy of note that it was a very rainy winter here in Lower Slower DE, and the inside of my car was wet alot. The convertible top leaks, and water collects in vinyl that covers the amps and convertible top motor.
Hello from a fellow Long Islander, now transplanted to the DE beach. Your picture by the Jones Beach Toll Plaza brings back great memories of Beach Boys and Jimmy Buffett concerts in the 80's and 90's. This post is long and I will send in sections. Sorry, but I really do need your help.
