Ok guys, I had my eclipse system ripped out of my 96 talon esi a couple months ago. So I decide to go back to stock, so I buy a infinity cd/cass off of ebay, and the amp & din cable off the club vendor market. Get it all put in, works great except I have no volume control with the head unit. The volume control turns, and pushes for power. Turns on and off fine, cannot change volume at all. Amp? Cable? Volume rheostat? Any ideas?
