If you can find 2x4ohm go for it, if not go 4ohm, but take in consideration buying a separate amplifier for the sub with a high-low converter so you can transfer the system when you change cars. Installation is fairly easy, i've done it myself.

You cannot bridge the amp because is already bridged but on my mib1 i ran without problems a 4 ohm sub. Just select a pair of wires to connect the sub, isolate the other and, the MOST IMPORTANT thing, switch polarity of the selected pair of wires to shift the bass to front seats.

SInce april i run without any problems the following setup. Trunk: Subwoofer JBL Club 1024 250W/4Ohm with the custom Basser box and JBL Club 5501 Amp pushing the sub at around 275W because of the sealed enclosure. I had to use a high-low input level converter because using the high level input present on the amp would throw him in protect mode... don't know why. (input voltage < 12v) Front: I replaced them with the Hertz Cento C165 woofers because the spider on the left one broke and .. prrr prr prr. Although the nominal impedance is only 3.1 ohms, i didn't have any problems of overheating or shutting down or any thing.
