well, heres my opinion. you dont need a 12, or even a 10. thats going to be a lot of bass, go with an 8. i have one 8" jl audio w7 in my explorer, and if i turn the bass on it down, the rock hits so clean and SO hard, if i turn the woofer up, it hits as hard as most of my friends' tens (cause its a w7)... jl audio makes some HIGH quality 8" subs, and if you dont want the ability to have LOUD bass, dont go with a w7, get an 8w0, maybe 2, they will take less of your trunk, take a smaller amp to push them, be cleaner bass, and just all around be better.... thats just my .02. i have had 3 8" w0's, one 10W3v2, and one 8w7........ out of those, the order from best to worst is the 8w7, the 3 8w0's, then the 10w3v2.... supposedly they are coming out with 8w3v2's, if so thats probably what your looking for. just trust me, 8 inches is a sub for rock, not for rap. its made to be cleaner, not to drop low. but since rock doesnt have a whole lot of low hitting bass, an 8 is perfect... and crisper and cleaner than any other size... and if you get one 8w7, it only takes 300 watts to run it, which aint much... 8w0 will run off 100.... so you can get a cheap 200 watt amp, and 2 8w0's (or 3 and a 300 watt amp)... and trust me, you wont be uphappy. oh, and jl by far outranks the others in cleanliness of the bass.... which is what you go for in rock bass....
