I just wired in a sub and amp and after I turned my car on I noticed my multi info display wasn’t turning on anymore and my dome lights don’t work. Also noticed the electric key fob stopped opening the doors… any info on this?

 

obvious answer, un-do what you did and see if that fixes the issue. If it does, figure out what you wired wrong. Check all your fuses to see if you melted any, but it sounds like you got something crossed

 

so I changed some fuses related to the issue even though they were all fine along with check all the wiring to sub/amp and still having the same problems

 

Use a voltmeter on related fuses and see if voltage is there. If not it is possible a wire was burned and separated. A wiring diagram will be needed after this to see what is going on and if a constant 12v is supposed to be on one side of the fuse and is not a wire can be run to that point from original source on diagram bypassing the open circuit.

 

Did you change the 10 amp fuse in the passenger side fuse box?
