So it’s a cheap powered sub I got off a friend. It says it’s made by bermans. The install instructions say it will work off high level inputs and what I’ve read online the high level inputs should be around 12vdc but I’m only reading 22mvdc.
So I tapped my rear speakers the other day for a powered sub install and the sub isn’t powering on and I’m only getting 22 mili volts at my taps. What am I doing wrong?
