First off I drive a S4 with a Taurus e-fan and FD alt a alpine Mono amp (for the sub) and a alpine four channel amp (for the rest of the speakers) just put the stock seats with the headrest speakers in today tho because I have no headrest amp they aren't working yet.

So as I was driving back home from the Mayweather V. Ortiz fight (HELLA cheap shots by Mayweather btw) my stereo cut out and all my idiot lights came on. I pulled into a gas station as my car dies.

I then pop the hood to find that the main fuse(80A) is still intact but the plastic cover is all melted. The empty fuse slot which is now a 30A fuse and powering the FD alt and the Sticky starter issue is brown and charred.

The only thing that has changed is I plugged in the stock seats with the headrest speakers. They aren't even powered because I haven't hooked up the stock headrest speaker amp. What could be causing this? I NEED to be able to drive to work and back on monday-friday so i NEED this fixed.

My guess would be that the fan and the relay is causing too crazy of a draw or somehow plugging in the headrest speakers(even though there is no amp to power them) has caused some sort of short. The last guess makes me wonder how much more it can get screwed up when I actually hook up the headrest speaker amp.

Any help/suggestions would be greatly appreciated.

What does this mean?

 

if the plastic is melted on the fuses there is appernly quite a bit of heat and your fuses are probably shot anyway... pull those fuses and see if you have a short to ground on one of those empty fuse curcuts... just take a multi meter and stab both blades with one of your leades on a good ground on the car and one in the fuse contact area.... since those both shouldnt be gounded if you have ANY resistance from the fusebox to ground you have then isolated wich area you have a short...

another way is to pull those fuses and replace and if the car starts and acts normaly then you let it run with everything on and watch for signs of the same thing(melting fuses) but this could lead to other damage and may not be the best way to diagnose... i know of a few Government electricians that have held circut breakers in so the bad compont would "overload" itself and start smoking... and then they have replaced the bad component...

 

The only thing I changed electrically yesterday was reconnecting the driverside headrest speaker connector. I doubt that change brought about this issue. It wasn't progressive at all just sudden onset.

When I stab the connectors as Nightstrife mentions (one on ground one on the 80A empty slot) I get a reading of 3/4 with the key in the accessory on position. I'm fairly inexperienced when it comes to electrical problems.

 

Solved the problem. Turns out I had forgotten that I had wired some things in improperly as a temporary fix.
