What sound system should I add to my 2003 Ford Mustang 2 door, 6 cylinder, 3.8L?

I don't know much about cars and audio systems but I was looking to add a good audio system to my car. I basically want the car sound to be a lot louder, but sill be clear. I also want a stronger bass. Basically I want the car to be able to shake if I want it to. I looked into the Mach 1000 audio system but not sure if that s good or what to get with it if you even do that. Like I said, I'm not a car literate person.

There are so many choices it is hard to know where to begin without you at least specifying a budget. We could recommend a system that costs thousands which would be pointless if you can't afford it. You might also bother to mention how many speakers your car currently has, their size, and their locations and if you are happy with the current radio / CD player or not. Just adding better speakers and an amplifier would help, but if you require bluetooth, an aux plugin, or other features, you'd need to specify that. Yes, you are not a car or audio literate person because you don't even know what information to supply.
