Just a word of warning. When I replaced the 6x9 speakers in my blazer, any decent speaker was way deeper than my factory speakers. You'll want to double check the depth that your vehicle can support and then figure out what will fit or how you have to customize to make it fit. I think you can find this info here.

And your perfect subwoofer enclosure is here. (I didn't say it was cheap )
