So my sound system was running fine for a couple of weeks.
Then outta the blue i notice my sub isnt work anymore? cause the amp wasnt turning on.
brought it back to straithfield they chcked it and it was working but it wouldnt work in my car?

I've already checked:
12V = ok
3x Ground = ok
amp wire = ok

I've been told if the rca leads ran along with the power cable then it'll screw up? is it true?
Anyone ever experienced anything like this? know what could be wrong?

Thanks guys
