JL is the top notch by far. I have heard and installed quite a few brands and nothing has compared.
I was running two JL 12w0 in a sealed box with a weak 275 watt amp, and it sounded cleaner and had more range that my friends $2k system.
Im currently looking into a 12w6. Dont know if you have a budget or not, but thats the one im looking at. Has the range and the depth or the w7, but its cleaner, tighter, and most important, less expensive.
i have owned/installed every single product jl audio has ever produced through my shop all the way down to wire and distro blocks, the w6 in no way compares to the crisp clean sound of a w7, it is not tighter and does not have the same linear excursion aka "depth" in your case.
I used to compete in IASCA and USACI sound competitions both sound quality and spl, i had 2 oldschool 8w6's in mine and it would knock your head off~! jl audio sounds reallllly good and is one of my most favorite products but there is other options out there that is easier on the wallet and will sound just as good.
First look at your goal. we will throw distortion out the window (to a certain extent), distortion for subs is not as meaningful as so with door speakers. think about it, your subs are locked up in your trunk and playing sub-bass frequencies (40-80hz), therefore; distortion will not be heard as well.
I used to run subwoofers from a company called FI Car Audio, dont know if any of yall have heard about it but they make AWESOME subs for a decent price, i know the owner Scott and have put a few systems in for him. check out their site at
www.ficaraudio.com and browse around for subs.
You will need some nice power for the sub(s). Forget about those shitty pyle,pyramid,etc. no name amps that say they will do 4k watts and have 2 20 amp fuses plugged into them lol. i would look into rockford fosgate for power for your sub(s). just browse around on ebay and see what u like. My personal favorite is the p300.1. that little amp has some balls!!!
let me know if i can be of any more help! :azn:
