2 things to determine first:
- determine what each wire set powers which speaker, maybe by connecting to a stereo. Mark/keep track of the results
- then for the remaining speakers not determined in step 1, determine where the speaker wires end- hopefully it’s not to difficult.
Afterwards, determine how you’d like to control the speakers. For example, separate systems, or a centralized setup. After you determine what you want, then it’s time to look at options which may include rewiring or maybe bring in a professional, etc.
