I've tried using the 5x7 rear speaker adapter posted in this thread, all the screw holes line up but it doesn't seem to have any holes for the 2 plastic posts (seen here https://www.youtube.com/watch?v=dHNYuntv00c&t=62s, they are right next to the two closest screws). Am I missing something?
So the 12V battery died on my 2014 Spark EV (had it for about 1.5 yrs), and I noticed that the previous owner installed a regular lead acid battery in it. I'm replacing it with an AGM battery now, but should I be worried about long term damage from the old battery?
