Hi folks. I'm looking to buy a basic used Up but I'd really like decent sound from the speakers. I'm finding few basic models with the sound pack. I'm fairly handy and wondered if anyone had swapped the standard door speakers for good quality ones. I don't think I'm up for self installing the full speaker pack which I've seen elsewhere in the forums. Just a basic swap for quality single units that will fit in the doors without modification. A brand and model would be great. Basic instructions for replacing the speakers would be fantastic. Thanks folks.
