I've vibe speakers and tweeters all around and a vibe sub in the boot, not much bass fromissions speakers themselves but the sub fills that void, very happy with it all around, Sony double din 4x55w too.
I still have the same speakers that I bought the car with, not sure if they are oem or not but as I have a Vibe competition Sub and amp setup I'll most likely go with a Vibe component set and a small amp to drive them but honestly I'm ok with what I have for now
