Yep, those are wire caps. I am actually currently using the 2x since I couldn't find a 4x ballast at Home Depot. I eventually found a 4x ballast at Lowes (It wasn't Advance or GE, but an OSRAM ballast, which is still really good). So I have been thinking of trying the two 18" bulbs in series driven 4x. You should go ahead and try it! At 2x, it is only pulling less than 0.4 amps, so there is plenty of room for more current. Try hooking all four wires and if the bulbs get too warm for you, go back to two.
