for about a week now my head unit has decided to cut the sound off and then back on when it wants to. at first i thought it was a short in the wiring but it seems that if i hit some (it doesnt seem to matter which) of the front buttons several times, the sound will come back on. i have 2 10 inch subs attached as well and they just stopped working all together today while the other 6 speakers i have in my truck still work (somewhat). im really starting to get annoyed hopefully theres someone that can help.
