when shutting down my system the speakers squak


i have jbl three way loud speakers, they are tri amped. im using sae power amps from the late 70s and early 80s. no matter how i shut the system down, preamp off first and power amps second or the other way around, i get ungodly squaking sounds from my speakers. my power amps are plugged into a adcom line enhancer. no one ive talked to knows why this occurs and how to remedy this problem, do you?

Turn the amp off leave the preamp on all of the time. It uses very little power and will last longer and sound better.
