It's your first setup? Order ya a head unit and make sure it has at least two sets up preamp outs. Look into something simple, get a pre-fab, pre-amped rockford or kicker box w, 2 12"s or something. Get some coaxials for your doors and amplify a couple 6x9"s for the rear deck. I'd also get someone who knows a little more about installation and fabrication to help you out if you're planning on doing all the install yourself, you can do plenty with a grand, you aren't going to get anything SUPER loud. You're 17 though and u wanna impress ur friends, just check the above out, and if you decide you that'll work for you order, install and impress. Be complacent with your stuff but don't get greedy until you have bookoo funds, lol.
