I have a Alpine 7893 connected to a Concept 2ch amp which powers my Boston Acoustic component speakers... my problem is that the mid and high audio will drop down. The best I can describe it is its similar to when your ears pop when on a airplane and the sounds suddenly come into focus except its backwards. When listening to music with the volume turned up around 25 the audio will suddenly drop and seem quieter and less clean and distinctive.

I have disconnected the speakers from the amp and connected them directly to the head unit and the problem still exist and seems more noticable.

I was wondering if this could be the headunit drawing to much power from my old weak battery?
or if the headunit could be dying?

The head unit was in a car crash about a year ago but the problem has just started within the past month or so.

The volume drop isn't much just enough to annoy me. The audio drops with cd changer input/cd input/or tuner.

Any comments/surgestions would be greatly appreciated.
