Getting a new 06 Coupe LX next week and am wanting to upgrade the system. I really can't afford it all at once being an 18 year old that works at a Honda Dealership but I really would like to upgrade the system over time. My questions are pretty noobish but I am a noob when it comes to this. I guess I would have to have somebody install it for me so factor the price of installation into stuff also. What do i need to upgrade first? I guess I will need a sub but I really have no idea what that is. What am I looking at paying for the sub and im guessing ill need an amp also. I want the best value for my money which means descent at a descent price. What next? And what am i gonna look to spend on the overall whole thing for the system. I'm just looking for an upgrade so I never sit there and think "that sounds bad". Also, I will be playing everything off an IPod so take that into effect.
