The problem is there isn't a good one around here, all we have is guys that know how to install giant subwoofers and shake everything within a 500 yard radius. Hell, I sat in the car that belongs to the owner of the biggest local audio place and it was like they took what is wrong with our system(too much mid-bass) and amplified it. It wasnt even turned up that loud and i couldnt even make out what song we were listening to. And this was his example of their best custom application. I wonder if someone could compile a list of components that will work together and wont require modification of the car. They're knowledgeable enough to install them I just dont trust their reccomendations as car as the system itself goes.
