So my sub hasn't been working right since the dealership cut them. I had just wired them right to my HU instead of the switch it was. Well when I went to wire it back to the switch today, the fuse blew for the wipers. I replaced it and wipers worked. I turned it back on flipped the switch and fuse blew again.

So I just wired everything back to the HU itself, replaced wiper fuse...but wipers still wont work. I tried a couple other fuses but the wipers still will not work and the fuses are good.

Any ideas?

 

Are you talking about the wiper fuse in the bcm.
To blow that you would have to be drawing power through the wiper switch.
Explain HU and what switch ?

 

IN the panel on the passenger side. Its working now though...strangely enough, just out of nowhere.

I seem to have that problem starting too. Twice this week I tried turning on my car, and nothing happened, and key gets stuck in the ignition, then after a few minutes car will start on its own...

 

That sounds like a ignition problem.
You have to watch how much current you draw through the ignition,The contacts are designed to a maximum .Thats why they use relays for everything that draws substantial current.
Your subs (amp) should be powered straight from the battery and turned on via the remote wire usually blue.

 

I was going to wire everything that way this weekend actually. Right now its powered through my unused sunroof, but im not super smart with cars yet, but I dont think that would affect the ignition though...
