Just want to install some 6x9s in my ep3. I'm changing my head unit for a sony double din but do I have to amp the 6x9s? I know it'll probably sound better but I don't want to buy an amp so correct me if I'm wrong I can just run the 6x9s along with the oem rears by either running a pair of cables from the head unit all the way to the parcel shelf for the 6x9s or connecting directly to the oem rears to the 6x9s. Just after advice really
