I have 2 JL 13TW5-3 subs that are in a custom box that goes under the back seat of a 04-08 F150. This box was beautifully build to spec and installed by Earmark Car Audio in Dallas TX. This is a great sounding set up, very deep tight bass. I was totally impressed with these speakers. I'm selling because i just traded in on a new Platinum and I'm just going to live with the factory set up because I'm old now! I'm looking to get $800 for the entire set up. I paid more than twice that less about a year ago. I'm in the Dallas area can can meet with in reasonable distance, shipping would be extremely high because of size and weight, but we can always work something out. I have have pictures of it in the truck as well as out, so please send me your email and I'll forward them. (I also put some in my album)
