I am in the process of installing a LOC. on 97 cl
1. Do i connect it to both of my rear speakers. Thats what i was told you to so i ran it in with them.
2. next, i need the to know what to do with the remote wire(pretty sure thats what its called) wire that goes into am from head unit. Do i splice into it before it goes into the bose amp. If so is it the blue wire or which one.
3.can i ground all my wires from loc and amp to the same ground spot where the bose amp is grounded. would it matter if there all grounded touching each other. thanks for yalls help

I am assuming LOC is a line out converter. Or some thing of the sort. YOu don't need it if you are putting in a sub or a interior amp, just splice the RCA.
