Headunit overheating

[DAVE_RSi]

mates 172, he has an mp3 player headunit in the car

headunit was pulled out a week ago, rca cables and remote cable plugged into the back

amp isnt working but left rca and remote cables in,


now a week later after 30 minutes of driving the headunit gets really really hot and it struggles to play the cd's

headunits been pulled out and put back in again with rca cables removed, and it still did it?

what could be the reason? cables catching the cage or something at the back of the headunit

what h/u is it?

i know alpines have fans in the back to try keep them cool, so if thats covered it'll probably overheat.

the only other thing is what speakers is he runing from it?? (if any)

 

[DAVE_RSi]

he's running standard speakers

its a kenwood mp3 player

never had problems with it before, until a week after the wires were plugged in back for the amp

mine gets hot only when the heaters on, but never gets so hot it effects playing cd etc? ask him if he has the heater on its hottest??

 

[DAVE_RSi]

heaters not on, he had the headunit out yesterday and it still did it


big block of metal at the back is where it heats up the most apparently
