Infinity Stereo Wiring, 1995 Dodge Ram

A little more info for you.

The Bass Started going off and back on with no set pattern. I could hit a bump and the Bass would go off, and it would ether come right back on or take about 5 to 60 seconds to come back on. When everything is cold it takes about 10 minutes before it starts going off and on. I thought it was the Infinity Radio so I spent a couple hundred bucks on a Nice Head system only to find it doing the same thing. Then I remembered that right after I got this Truck the Bass quit working one day. I had to replace a Relay to get it back on, But I dont remember where the relay is. I have looked behind the radio, behind the glovebox (not possibe) under the passenger seat but I just dont remember where I found it the last time.
