It really depends on your experience if you should do the install yourself or not. I thought it was actually one of the easiest installs I had ever done but it was also one of the most basic since it didn't involve multiple amps, crossovers, EQs and so on. If you are experienced and like to do things yourself like I do, go for it, you should have zero problems. If you are not so experienced or are unsure, definitely get it installed by a professional like nafs is doing. It is always nice to have someone you can go back to if anything goes wrong. I am sure the shop you are going to is top notch nafs but but for those looking around, don't judge an installer by the vehicles in the shop. I have dealt with many shops over the years and on average it was the ones working on the cheaper vehicles that did the superior work and some incredible installs. I have dealt with shops whose clientele was only high-end primarily due to location and they kept coming back because they didn't know any better. I have also dealt with shops whose clientele were always on tight budgets yet they were always able to turn out incredible systems working with those budgets. That is not always the case but like the old saying goes, don't judge a book by it's cover. Just my $0.02
