Alright guys so I want some speakers for my 98 mercury mountaineer it has a mach system it ask if I do when I click fit my car. Anyway I would really like 6.5's but I'm afraid they won't fit I think the depth I have is around 3.5 inches I want a nice pair would someone help me with what I need. My budget is around 100 give or take 25 bucks. I would buy used if someone had a set that would fit.

I have checked the sites, but I don't really want mainstream :/ ..
