Hi Cakyol
Darn, a legitimate question on this forum. Ok, I'm a real EE. I'm not aware of a high failure rate in amplifiers, but perhaps just that...unaware. Are you concerned with a specific aspect of your system that you want to protect your speakers with something faster than a fast acting fuse? I admit to not having used an SSR in your application, but like you, would be curious about any acoustic artifacts associated with putting even a low impedance semiconductor in series with the speaker wiring. On the other hand, as infrequently as a mechanical relay would be switched hot, i.e., under heavy load, I wouldn't have any concerns about contact erosion or wear for one with contacts that are properly sized. Also, I'm curious what you were going to use as a derived control signal for the relay of your choice.
Keep us posted on your progress and results!
