I've just turned 16 and I'll be getting a car in a couple of weeks. Chances are that I'll get a 2000 Isuzu Rodeo, but it's not certain. Anyways, I know that I'll want to put a system in it, but I'm not sure where to start or what to buy. After looking around, I think I want to get an Alpine 7894 HU because I want MP3 playback. However, I have no clue where to go from there. I enjoy listening to all kinds of music, from rock to rap and even some country. I want to be able to turn it up fairly loud also. Could anyone be kind enough to give me some suggestions on what all I need? My budget is around $750-1000 including the HU. Also, does anyone know of any good online stores? Any help will be greatly appreciated, I am totally new in the car audio world.
