Void the warranty? Sounds silly to me. They may recommend not biwiring because they think they sound better with their own jumpers, but there is nothing that could damage the speakers with biwiring.
How could they void the warranty? They could never prove you operated them this way.
Are you intending to use the 8 ohm and 4 ohm taps at the same time? The cabinet hooked to the 8 ohm tap will be getting more power. You should you use the same tap for both cabinets.
