Infinitys are good quality. My father has a full infinity system in his camaro and it sounds really clear. He has two 3 inch speakers under the windshield ( hidden on tray underneath dash), 2 6x9s in back and a 10 inch sub and amp and an amp for the back speakers. The 6x9s seem to put out a fair amount of bass and are plenty loud enough when the roof panels aren't out.
Listen to the infinitys before you buy them and compare them to something else you are interested in. I think you will like them.
