Hi guys. Where to start. I looked at a job today
at a water park that has some problems. The park
used to have a 70v audio system. Last summer they
installed an 8 ohm system. Problem is, there 12
channel amp keeps blowing. It will run for about
3 hours, then shut down. This is why I was called.
THEY installed it? It's probably not totally related to the blown horn... They probably wired it really funky (shorts), bad terminations, and who knows if they wired things in series, series paralell or whatever. Sounds like a total re-wire job...
Can you check to see what the amps are seeing for impedance?
Figure in plenty of time to look things over first...
70 volt is probably the ticket, like the other guys are suggesting.
