PLEASE change the twist connectors to some type of crimp, such as butt or male/female crimp connectors. You'll probably have to use 6 or 8 gauge crimp connectors to fit all those wires in but it'll be a lot more secure and safe than the twist-ons. I've seen many times folks using twist-ons only to have them come loose/off with engine & road vibrations. You're asking for another problem keeping/using the twist connectors.
