Fosgate is good stuff, but like with everything each company builds crappie stuff for price too. I have always gone to Crutchfield. Com to shop around. Not really to buy. But they have a selector tool that tells you exactly what will fit, but more importantly, solid reviews of the products. And it's fun to see. They give you installation instructions too. If you call, the guys give you what sounds like honest advice. Then you can shop around.
