Make sure you don't have an exposed/cut wire back there. That is exactly how my fuse 21 kept blowing... a wire was grounding out on the aftermarket stereo sleeve after 6 years of rubbing.

i had this SAME issue

Today i was putting in my headunit and while i was putting it in my stereo obc and rpm meter went out that i know of only those things. Is there any wires behind the headunit or around there that couldve gotten loose? or what can i do for this problem??
