Hi everyone im new to this forum, i have a 2007 subaru impreza sti i had a stock deck and bought a aftermarket one with an amp and 12" sub. I tried installing with the right harnesses and now have no power on the radio my interior clock/dome lights dont work and my alarm on my keychain no longer works! please anyone with info or anyone near spring hill that knows someone please comment!!!!!! I also brought to best buy to see if they could trouble shoot the issue and they couldnt figure it out! maybe a harness problem..?

 

Sounds like a blown fuse

 

checked all of them. they all seem to be fine. would it have some kind of theft on the car with the alarm that would make everything inside stop working??

 

The constant power fuse is blown. Check the panel under the hood. In 99% of cars the constant power to the radio also feeds the dome light.
