Anything I'd have to know to upgrade to the bose speakers in an 8p 3door do they need a specific wiring harness?? have the standard speakers none bose in it at the moment and have they got an amplifier and is it the same plug for the bose amplifier if so for a plug and play simple set up and is it the same for the speakers any help or advice will be appreciated thanks lads

Think it will need coding I'd using the amp. The speakers should be just plug and play in theory
