so I just finished upgrade all 6 speakers, cross-overs, HU, steering wheel connection adapter and ran all the cables needed for my sub/amp. BUT my poor amp/sub isn't working.
As soon as I turn on the engine, the onboard fuse of the amp blows instantly. So, I took out my trusty multi-meter and got some results that look kind of funny:
- ground wire and battery wire have a 12v on ign and 14v when engine runs
- ground wire and power turn on have the same
Does that seem right? I'm guessing the flux is from the alternator.
I'm not sure what to try next. I did notice that the inline fuse at the battery is a 40a and the onboard amp fuse is a 20a (also tried a 30) which blows instantly.
Not sure what to test next. Any suggestions? ... besides going to an audio store for diag's lol. I'm thinking it might be a dead amp.
