Female spade crimp connectors for AR 2ax speakers source?

I am re-wiring my AR speakers and can't figure out the crimp connectors I need as their sizing nonmenclature is a mystery to me. The tabs on the drivers are 5.2 mm wide and need to accommodate one 18 gauge wire. The original trim pots were corroded so I got aftermarket ones suggested on this AR forum, which require a resistor between tabs B and 2. The tabs on the new pots are 4 mm wide, but they need to accommodate what amounts to three 18g wires. I have found 4 mm connectors, but they will hardly accommodate even one 18 ga. wire. Can anyone help me out with a source or two for these two crimp connectors? Thanks.
