wied Posted October 4, 2014 Report Share Posted October 4, 2014 I'm thinking it has something to do with my RCA's. I do have two amps, one for mids and highs and one for my sub. But i do not have the 2nd amp daisy chained to the Hifonics, it's sent straight to the head unit just like the hifonics, because my last amp did not have the option to be daisy chained (could this be the issue?)

afrakes Posted October 4, 2014 Report Share Posted October 4, 2014 Switch your rcas around (not at Hu but at amps), if the Zeus works then you know it's either crappy rcas or a problem with the output in the source unit. If it still doesn't work then it's more than likely an amp problem. Do some testing using the process of elimination man.

afrakes Posted October 5, 2014 Report Share Posted October 5, 2014 Now, as weird as it may sound, try to see if you can get output from your sub amp using the pre outs on ur head unit that u used for ur mids/highs amp. Don't go full tilt by any means, jus see if you get ANY sound coming out. If yes, then it's a h/u problem. If no, it's a amp problem. Now u know what's shot.
