can anyone recommend a good adaptor / convertor so that i can run a aftermarket head unit in my mk5 fiesta please. what needs doing? what do i need to buy? also im planning on having a amp and 1 smallish sub in the boot and at up some point 4 new speakers to replace the standard ones. however i planning to sell the car a few months after xmas so im not sure whether i want to be messing around with fitting new speakers and then having to take them back out to sell it. can the standard 1s cope if i get a half decent head unit?
cheers
