Check power and ground at the battery.

tightened connections a little at battery but weren’t loose loose. Lugs are tight no movement on board gains are where they’ve been set for a while don’t know why gains would be issue now. It started getting low and than back to high in garage earlier at lower than I normally play volume. Was told amp sounds like going into protection mode but can’t find anything loose loose

I hate to say it but the SD quality control is garbage so if u triple checked all connections and gains it very likely that the amp is the issue.

Don't get me wrong, I run all SD amp due to the raw power in a small footprint but about 1/3 of the ones I have purchased were a do-over.

Their warranty is great, just not the initial quality control.

Everyday someone is getting a doa evox or someone is sending one back. Pretty alarming in my opinion
