Which of these subs should I go with.?

Hey, I'm looking to buy a pair of subs from "Sonicelectronix." (a car audio website) I have slimmed my options down to a few different subwoofers. Here they are: MTX Audio TR5510-44, or the Memphis 15-M3104D, or the Boston Acoustics G5-10-4. They're all 10" subwoofers, but I don't know which ones to go with. Any suggestions? Or if you know of any other recommended 10" subs, let me know. NOTE: I'm putting them in a car, in a sealed box. I care all about SQ. I'm going for a clean sounding set of subs.
