Ok, well I guess I'll start with what I have. I am just starting to get into the audio components, and this is the first car I've done any of these sorts of mods, so I want to do it right. Right now, I have a set of Infinity Reference 6.5" door speakers, with components (tweeters and crossovers), and Infinity Reference 6x9's. I wasnt happy with how it sounded powered only by the Alpine head unit I have, so I put an amp to them, a Kicker 350W 4 channel, running 90W rms to all speakers. It sounds good as hell, but now I am looking into a sub... The quality of sound is there with the speakers I have, now I just want a little bump in the back

I know for sure I want to get a JL 10" W7, but I have found 2 different ones online, one says its 1000W peak, 500 rms, and the other says 1500W peak, 750 rms... This particular sub runs at 3 ohms, and I want to know what kind of amp to get for it, as cheap, but good, as possible. Best bang for the buck. I am running low on cash, but don't want to buy cheap shit, if that makes any sense haha. Can I run an amp at 4 ohms with this sub? And also, should I run a capacitor? Or just do the "Big 3" wiring mod? And if anyone has any other suggestions as to good 10" sub and amp combos, I am open to anything. Its just that I know someone with a 13.5" W7 and it hits HARD as hell. But let me know what you guys think, and like I said, any suggestions are welcome! Thanks!
