Stereo Problems

Anyone ever had a problem with the stereo draining the battery. It's the stock head unit in my '94 Blazer. I've checked the hot lead, but couldn't find any trouble spots, but whenever the head unit is installed, my battery is drained. I haven't had a chance to install another unit to see what if the problem is the unit itself. Any suggestions would be greatly appreciated.

my suggestion is talk to a radio specialist real quick at like at pep boys or autozone. you can also buy some parts that go onto your battery to prevent it from draining you battery.

I had the same problem..turned out to be that just the battery was old that fixed the problem
