I have a Probox with 10" JL audio W3v2..It has been sitting in the garage..it fits under the seat..Not sure what is really worth but paid close to 200 several years ago..100$ plus shipping??
Clay, do you know if JL subs are reliable and hit pretty hard? I see you are running two memphis subs, and i didnt know if you have ever gone with JL before.
I have personally never owned JL but I know that they are a quality company. I have mostly done memphis. (had kicker subs for a while). I have friends with JLs that swear by them and love them. As long as you aren't expecting amazing results out of a single ten under the seat then you should be happy with it. For that price I would not leave that set up sitting in his garage.
