i have an early 04 XXX motor. not the chrome like finish one but not the flat bottom one. exact same as the 05. there is a scratch on the bottom that came with the sub when i traded for it(was an 18).
i was initially going to go for dual 15's in my car but i can't get the space required so i'm switching it up. the motor currently has a 12" basket with SX soft parts and a blown coil. sent 3k burps at it.
