147 3rd party amp and sub troubleshooting
I had an amp and sub installed about 4 months ago and all of a sudden the amp has stopped working.
I checked the fuses on the amp itself and they're still ok. The wiring goes into the back of the headunit (standard alfa headunit..cassette with multichanger) and rather than get the headunit out, I wanted to check the fuse.
However, I don't know which fuse would have been used for the external connection on the headunit...can anyone help with this at all?
