Hey guys, sorry to sound like a complete retard, but I just bought a 2000 ford contour and I'd like to upgrade the sound system and add subwoofers when I manage to pull together enough money. However, I know almost nothing about installing a system or even what sort of parts to buy and what those parts do. I tried to search online for compatible parts and such with no luck. I was wondering if any of you would be kind enough to help me out a little. I'm on somewhat of a tight budget seeing how i'm going to college full time, so please try to keep any ideas within or under five hundred dollars for the whole thing. The stock speakers are mediocre at best but I can survive with those, I'm mostly just looking for a good set of subwoofers that won't cost me my left arm. Not to ask too much of those of you that respond, but since I know nil about this topic, I'd greatly appreciate it if you could explain exactly what else I would need to make this work. thanks a ton!
