I checked on crutchfield but didnt return consistant results, so figgered stangnet can tell me w/o having to pull them. What size are the dash tweeters, door speakers and the rear seat/pillar speakers on a 89 GT hatchback? I dont wanna put a mondo system, just some good speakers so I can hear it. I got some Kappa Infinities in another car and they are awsome. If newer nice speakers dont fit the stock holes, what sizes are easily mod/bracketed into the stock spots? Thanks
