I need some help with my rca wires that are connected to my headunit . before i noticed that i couldnt turn off my sub on my deck and i couldnt control my sub on my deck i switch around some rca wires and i can turn off the sub now and control it from the deck but the wire i took off seems to be my front left speaker so now i can control the sub but there is no sound on my front left speaker. im currently running a 4 way amp for speakers kicked amp for rockford sub. and f90bt hu.

 

sorry what im asking for help is how do i know what rca wires are for what? i know the ones on my head unit are labled like rear speakers and stuff but what about the other ones?. and is there suppose to be a cable on the back of the f90bt remote slot?

 

If you look on the back of your radio S/W is for your sub, then F for front and R for rear. You might have to pull up your e brake, go into your setting and mess with that. You should have brought it back to a different shop. But since you messed with it they will have to charge you.
