they are the Concept HZ124's. Unfortunately the guy already had the amps and everything else installed up north. Apparently it took the shop a couple months to get the job done, the guy wasn't very pleased. He was very thrilled and happy with the box that I built him. I didn't get a pic of the install because I didn't want to keep the guy waiting. He's comming back during the week anyhow so that we can fix a problem with the other shops install. They screwed right through the back of the cab of his truck to mount the amps, and they only screwed them down along the bottom, one amp was comming loose, not something I would do and send out. So I'll be getting photos of the box installed when that happens.
