I did have buy 2 pairs of meta harnesses which is basically an adapter to go between factory connector and the new speaker. Not sure if I got the wrong ones or what but I had to open the metal end a little to get it onto the RF speakers. Also I did have to drill 2 holes into the pladtic mounting area to secure the speaker. 2 holes lined up great but had to drill for the other 2.
That shouldn't be the case. I didn't have to drill any holes. I reused the stock locations for everything.
and +1 for the metra harnesses. Get them.
