Alright, I'm pretty new to car audio. I'd like to get a nice head unit, some components, and maybe a small subwoofer or two. Is it tough to install all of those parts by myself? I don't imagine it would be too bad unless I want to replace all of the wires and such. Also, I want to do it myself so I know that it's a quality job and I'm going to be the one listening to it most of the time. One more thing.. how much would I expect to pay for all of that? I'm on a pretty tight budget as I'm saving up for a lot of other stuff too (i.e. home audio, computer, etc. etc.). Would something like $600 hold me off?
