Two 12W0v3-4 wired parallel to an alpine M500 amp at about .3 volts gain, wired parallel to 3 farrad cap. Subs are in 3/4 chipboard ported-box built to specs provided by JL Audio.

PROS.
Very good price
Lower than 30hz average responce.
Low rms (cheaper amp)
Good db's

CONS.
Does not do 20hz
Single voice coil
LONG BREAK IN PERIOD!!! these are pro subs! dont expect to do 250+ rms out the box

i have 2 12's in my silverado, the sound quality is great. 2 12's is enough to shake all the mirrors and stuff inside my truck. if youre looking to buy these subs, dont even think about it, buy them! best subs ive had so far! They Hit Hard!

So about six months ago I ordered two of the 12 JL audio W0's. I spent a bunch of time scrolling through subwoofers and many hours reading the facts. After a few days to think about it I went with JL. My brother has some W3's and they are awesome! After the hook up, break in, and tuning period was over i finally was able to crank these babies up. I was completely shocked!! 150 watts of Kenwood power going to each sub at 4 ohms and in a custom dual chamber ported box at just over 30hz and these subs will go so hard!!! Very loud for the hip hop music (which is what I mainly listen to) but will keep composure and remain so precise. Perfect for any and ALL music! All in all these subs are awesome, anyone who knows JL knows that there is nothing but quality when it comes to their products. Definitely a good buy, worth it!!

These subs are beast my 2 JLs hit harder than my brothers 3 kicker comps and his amp is a class D and mine isn't.. If you got the cash definately take the W0 over the WX worth the extra cash. I checked all around before I bought my subs here at sonic and they got the best price anywhere.

I bought two of these, wired them at 4 ohms in a ported box with 250 rms and they are loud and clear. I love these subs, they were cheap and couldn't sound better. I used to have two Kenwoods hooked up to my rockford amp but they ripped shortly after. They had roughly the same specs buy the jls go louder and sound a whole lot better. Very good subs for the price

This sub sounds great, can hear from a block away. Only downside (to mine at least) is that it blew in 1 month, dont let that stop you from buyin it though. This sub is great for the money and warranty will cover any problems.

All i can say is damn! I have a custom 99 s10 that i hooked up two of these to in a ported box. Running a quantam audio 1800 watt monoblock amp. These things pound!!!!!!! I have had many systems and let me tell you, JL is the way to go!!!! You won't be disappointed!

This JL sub is amazing its super loud i made a custom box for it and it is the cleanest bass ever. This sub really does pound do not underestimate this sub.

JL Audio never lets you down, these subs are great for the price on Sonic. Great sound quality, nice bass ported & sealed. Strongly Reccomend!!!

Strongly recommend these. Have 2 sealed hooked to a zx750.1 over powering each by 75 watts and these have been banging for along time. I wouldnt recommend under powering these by 250 each at least give them 300 each. If you over power them in a sealed enclosure they won't blow. They'l eat it up and make your system sound awesome.

If u want a budget sound you just need to get two of these hooked up at 2omhs with a JL JX500/1 amp running 2omhs. Will get good sound with ported box.

Okay, so normally I can care less to review anything but I decided to since all these other reviews pretty much suck. The subs pound good. They are very bassy with alot of thump. They are very durable subs and a league all in their own. Got 2 of these in a Probox with 1000 watts to them and they beat!!! The only bad thing I would say about this sub is not a lot of highs but incredible kind of lows.
