Electrical problem associated with all of my amps

Since I converted an upstairs room for my new system last November, everything was great. When the weather finally turned warmer, the A/C finally kicked on. However, as soon
as the A/C turns on the amps shuts down. At first I thought the Spectral DMA200 since it draws 800 watts continously was the reason, but it does the same with any of my amps.They all shut down; as soon as the A/C is turned off the amps start right up. None of the other equipment shuts down; because when you actually turn off the amp, the capacitors discharge and the music plays for a few seconds. So is it a voltage drop and I need something like a voltage stabilizer or do I need a new line run into the house. However, what is weird, the A/C and the stereo system are on different circuit breakers.
Any ideas would be greatly appreciated!!!

The problem is likely a too large line drop from your power pole transformer. A 200A service doesn't matter - what matters is how far your transformer is from your house. It sounds to me that it is too far (or too many houses on the same one) and you should have your power company check. A multimeter will not help you either because your problem is a transient one. Also, the problem can't be too small wiring.

I had the same problem and I had the power company fix it for free by installing a transformer just for my house. Your amp is shutting down due to simple undervoltage (i.e., overcurrent) because your AC compressor must be a big one. Good luck - you will need to make several calls to get it fixed.
