Thats odd of them - they let you pick balance tap, but make you do your own power conn. Deans would be my 1st choice and they're not that hard, it takes only a few minutes, but if you've never done them, I'm not sure I'd want to start on these as my very first attempt.
If your soldering skills are lacking in that regard (these will push a lot of amps, good connection is a must), go for maxamps pacs and get them delivered ready to plug and go.
