cool fade control

It's been a while since I've looked at my system but I'm going to have to now that my sound is acting up.  I only get sound from my rear right speaker sometimes.  If I make a hard turn to the right, sometimes the rear right speaker turns on.  If I brake really hard, the front speakers turn on. lol.  They stay on until I accelerate hard or they decide to quite down. Sometimes when all four speakers are turned on and I turn up the volume, the front speakers turn off.

I have one punch 40 for the front and another for the rear.  My rear left speaker doesn't play lows.  I went on a 36 hr road trip this december and my ktv-719 stereo stopped playing video but resumed playing after I got back.  It smelled like burnt electronics but all my speakers still worked at that time.  I have a relay for the remote sensing wires since sometimes I run a sub amp along with the other two amps.

When the front speakers are not working and I switch the rca's from the front to the back, the front speakers still don't work.  I think it's something wrong with my amp connections, but I find it interesting how I can manage the sound to travel throughout my car by the manner in which I drive shifting forces and sound to different sides.

I wasn't sure if it was a short or some loose speaker wires, but I'll find out when I have time to check it out.

I still like my fade control though. 

I really need to look for shorts before they cause any damage!

I was hoping for loose wires instead.
