JL 10W7 rocks. I put one in my truck to see if I liked it, well, I did. It hit hard and went low. If you've got the money, go for it. Just don't let the price tag scare you away. JL makes a high quality product and you get what you pay for in my opinion. Just make sure you have the power to run it. Have your local dealer set a 10W7 HO box in your car and take a listen. I think you'll like it, but that;s just what I say.
