i would agree with ali_rockon22 becuase ive heard JBL's studio stuff and its superior to others. It most likely isn't the same company becuase the ones i heard were from the early-mid 70's and were the last to use cobalt or some element that is illegal to use. but at any rate those are probably the best sounding, im not much of a bass fan so i dont know about subs.

Don't buy Sony. There's a reason it's called Xplode.. (Also, Sony HU's tend to be pretty flashy.. and that will often leave you with a pile of glass and a hole in your dash) Also, the power of the speakers doesn't really tell you anything. An efficient speaker will need less power than a non-efficient one obviously.. so that 1000000w sub is junk and the more expensive, lower power one is probably better. (The Klipsch RF-7 is one of the most well-known flagship towers.. $2.2k for two 150 watt speakers). The higher the sensitivity, the better. And yeah, don't buy brands you can get from Circuit City.
