Here's your wiring kit: The people you're listening to need to pull their head's out of you know where. First, the 13W7 has always had dual 1.5ohm voice coils. Wiring these in parallel will give you a 0.75ohm load. Though the amp is not rated to handle a load like that, I bet it'll play fine. If it overheats and/or kicks into protection, you'll have to run the voice coils in series for a 3 ohm load. You'll only get ~500WRMS out of that amp though. You should have thought about this before you ran out and dropped a G on equipment...
