I want to change my speakers and head unit at some point. I saw one guide online http://www.salisburystreet.com/wrx/speakers/ that shows how to do it. Granted, that guide is for an 05 wrx and mine's an 08, but I'm guessing it's pretty much the same idea.
So do I need the mdf spacers or are there any speakers that are the right size? If I do need the spacers, does anyone sell them or is making them my only option?
Also, so I don't start a separate thread: it looks like the head unit on the 05 has a connector plug from the car to the radio which avoids all the loose wires like ground, etc like with older cars. Are there any radios out there that I can just "plug in" to the connector that's behind my current head unit?
