rockford fosgate.....are the best iv ever heard......
they cost $$ 130 a pair but they rock
i got rockford.. 6 1/2 in my 93 s10..there deep and fit perfect.....
iv got a friend who used DUAL...which are made by jenson....and believe it or not for $50 a pair sound pretty damn good. better that others costing almost double in my oppinion.
