I've done a search for my problem and I've looked through some of the old posts to see if someone else had this problem but found nothing. I was attempting to put my HU in this morning and everything was fine until I took it back out to 'fine tune' my wiring job. Well, before I slid it back in place everything was fine but after I put everything back in place-nothing, complete silence. Now even my stock unit isn't working either so it can't be in my wiring job, right? I checked the fuses and they're good so I have no ideas.
