Hi I'm going to buy a sax 100.4 and I need to buy 4 5 1/2 for my Mazda plus cab 88 what would be good and hold and use that power best. Price ? And I guess I could run a bit bigger in the rear there is a metal panel I cut bigger for the front I think 5 1/2 Fitzgerald good in the door and I need to not be to deep or it might hit window. Also there is a spot in the dash for 2 4" should I put some in. Please let me know I'm new to this I have 2 Sa 8 v2 d4 I'm going to use saz 1500 at 1 ohm
