Anybody happen to know the door speaker size for the 89 mustang hatchback? I keep hearing that it's 5 1/4" along with 6.5", and I dont know what to believe. I'm looking into buying the EX3560 component system, and putting the woofers in the door and tweeters in the dash. Anybody with an 87-93 mustang hatchback please help out. Thanks.
