I’ve got a three year old that keeps turning off and only turns back on after pulling the power cord. I’m assuming it’s toast and needs to be replaced although I’m going to try and call support. I’m assuming this isn’t an easy fix for someone who isn’t electrical knowledgeable. I keep reading these subs are known for this issue so assuming it needs to be replaced, any other brands that sound good with klipsch speakers? Also, what’s the beat way to get rid of the amp without it ending up in a dump?
