www.crutchfield.com has a lot of info for noobs. if you don't mind paying a little more for your parts then they're a great way to go. they send you everything you need with every order and offer toll free phone support while you install everything if you get stuck. if you don't feel like paying extra for your shit just use their site to find out what fits your car and buy it elsewhere. you can also send them an e-mail after you get your parts and tell them you bought them somewhere else but want all the extra stuff they would have given you if you boughtthe components from them. they'll hokk you up and it won't be too expensive.
