I have installed an Alpine CDE-102 Head Unit. When turning it on a few days after installation (it was working correctly) it displayed "DC-Error" which, According to the site, means a ground speaker wire (or speaker wire issue), but, i just tried turning it on a few hours ago, after the car had been off. It works fine. But, just cut out again awhile later. I think the problem may be an overheating issue. Does anyone know how to "cool" a head unit if this is the problem? I am quite confused.
Thanks for all the help in advance.
