Keys To A Proper Sound System
This could be a book in itself, so briefly :
- Good electrical supply. A separate circuit(s) is recommended. A
sub-panel with an isolated ground is even better. You want to
clean and stable voltage to the equipment. Be careful about sharing
neutrals with the rest of the building. Use a licensed electrician.

difference. The 10 gauge we use has over one hundred strands per
conducter. Do not use solid core.
-Amplifiers. Use amps that have a 2 ohm rating and double or triple
power rating of the loudspeaker. Use

just be "coasting" along and never stressed.
- Use a equipment rack. Even if it's just a small system, put a rack

if you need to have RCA jacks.
- Wireless microphones & Cellphones. They don't mix. Do not keep
