I've had my Eclipse 5340 car stereo for around seven years now with no problems until recently. Starting a few weeks ago the sound (radio or cd) would go out every so often with the speakers making a weird thump noise as the sound went out, and the sound would usually come back on after a little while. But now these last few days I have not heard any sound. The stereo it self seems to be functioning fine, except when I push any buttons on the face they don't make a beep noise like they used to. I checked the radio fuse and inline fuse attached to the stereo and both seem fine. Anybody have any ideas?
My guess is your car amp is going. This dude told me that if you have factory "premium sound" (like me in a punk a$$ 92' Explorer) there's only two ways of installing it and either way you'll have to spend more money to fix future problems. 1. If you hook it to the amp, the receiver will blow (after a while) like what you explained about the fading in and out. If bypass the system amp, it's possible to blow your speakers.FLAT OUT!!!
I have a 1991 Saturn SL2. I don't have an amp or subwoofer installed. Unless amp is built into Eclipse stereo? Sorry I don't know alot about car stereos.
