Hello, im running a car audio business in gainesville, florida. i would like to know if anyoine knew of a head unit selector that could run about 10-20 head units and 10-20 speakers. i know about matrix systems already, but they wanted 10k for a 48 in 48 out selector.
Call a few electrical companies and ask for an estimate. They may have a few brochures, ideas, and even educated you. Usually an estimate is free, unless you buy from them.
