Alpine CDA7840 volume dropping out!

[intiti]

I have this HU that has been acting funny for a while. All of a sudden the volume will drop very low for a while and when I least expect it, it just comes back up. And when it does, it kind of resists at first (kind of like when you pop your ears!) Weird! Took it out, re-soldered and heat -shrinked all the wiring, and nothing. I'm inside the box now & nothing looks fried. Any ideas? It is 11 years old, so I'm thinking the amp is just gone? Anyone had this happen? I should mention that I've lived in Vegas for 5 years with it, and it has been through many triple digit days...Also, I have had to replace the fuse that goes to it ,the cigarette lighter and the clock about 4 times in the last 2 months...

11 years old = go buy a new one and have a professional instal it.

yeah i would suggest a new one but you can check the connections at the speakers to make sure nothing is touching

sounds like you should have your wiring looked at i wouldn't have anything replaced until u go any further than that. have you recently had any electrical work done on the car/truck like an alarm put in ??
