have an 88 xj6 i changed all six speakers to 4" jvc 160watt and put a 10" sub with an amp in i also put an aftermarket deck in a jvc kd-s5050 it worked but then all of a sudden it starter turning off rightaway when i turned it on i checked all connections and cd player fuse and hey where fine wondering if anyone knows where the radio fuse is on the car

 

Right side C1 10amp.

Moved to XJ40 section.

Doesn't sound like a fuse though.

 

i dont think its a fuse either put some one had a similair problem and fixed it by changing the radio fuse
