I'd go with pioneers, they are solid subs hit real hard with a good mp, and are rather cheap compared to the other name brands and they are just as good. i have a pioneer ten and 12 in my xcab, it's like a boss.
I am currently building a sealed box for a pioneer sub and the dimensions are super small, perfect for a std cab.
I have never before used Pioneer but we will see if it work well or not.
