Just got finished installing my 2 15" Lanzar DC's and MTX 1000d. It is the loudest setup I ever had or heard, Including SUV's and hatchbacks, but I'm sure some of you can prove me wrong. Oh well...just wanted to share with you guys. By the way stock speakers on my 98 GXE are actually half decent they will do until I can afford some components. Does anybody know where I can get my SPL measured in the Atlanta/Alpharetta area? Thanks guys.
