I have a Eclipse XA4200 powering two tweeters (Polk) and two coaxials (Alpine). I also have a Alpine MRV T757 powering two Sony 12s. Recently the highs amp has been shutting off and on while driving. Bass amp stays on and playing (not kool). Now if i turn the car to acc mode...it sounds like the music fades in and out. What could be the problem? Grounds to both amps are fine and are connected at one point. I do have a melted fuse block under the hood that will get fixed, but i dont think that's the issue. Thanks. If you need pics let me know
