When i turn up my subwoofers my speakers start to make a crackle/staticy sound. what could cause this. speakers are amped by HU

didnt someone tell you that its because there not amped?

also you need to explain more. these people are gonna think you just turn them up till they distort. explain the whole problem.
such as they didnt do them before you moved the subs. also are you sure you didnt **** with your amp settings when you moved them? like, an accident?

Check the speaker cables behind the HU. They maybe touching..
