My sister came to me her kenwood HU in a 95 isuzu rodeo.
Ok she had this hu put in a tCC many years ago. 4 years I believe. Anywho after 5 years no prolbems to do she came to me and the HU will not turn off when you turn the car off. You can turn the car off and take the key out and the radio keeps playing. also when you manually turnt he HU off the AMP stays on!! any idea what could cuase this like I said for years it was fine. Now it starts. thanks for any input in what i should look for in this problem.
