Not really besides saying making there own box with 2 8" JL subs and an $800 dollar amp lol. They do custom installs everyday hence why i couldnt get my truck in until Nov 15th. I trust they will do good. I could ask them when they do it to make a journal with pictures lolDid they go over with you how they are going to install everything? Like what parts and where they are gonna get the factory audio signal from?
