Look into Boston Acoustics G1's if you want to stick to a mainstream company. They have excellent sq and will get pretty loud for entry level gear. My amp is rated for 534w rms at 4 ohms and I ran that to a single G1 12 and it took it with no problem. After imp rise it was getting at least 400wrms which is double what its rated for. All of Boston Acoustics's gear is very under rated and over looked.
On a semi related note I had a cvx 10 in 2.8 sealed and it crushed the low notes but crapped out pretty badly on the high notes, but hey who likes high notes. I also ran it in 1.2 sealed and was pretty disappointed. I have heard Kicker's entire lineup except their pre 2005 stuff and the solo x and L5/L3 and the only one I would recommend is the Solo Classic. Its meant for small sealed boxes. I would only get it used because they jacked the price up on the new ones by about $80 and its not worth it anymore. I paid 170 for a 12 d2 new one right when they came out in spring 09 and put it in 1 cube sealed with a heavy layer of fiberglass resin inside and it sounded very good. I blew it up in less than a year, I was running it on a 750wrms amp and didnt know much about clipping so I'm gonna guess I was clipping it heavily at times lol. Anyhow - my point is if you dont clip it and don't exceed the rated power by much, it will do fine.
