learning together lol. If this guy is a professional installer, your wasting his time and ensuring once he is finished your project he will never answer your calls again. "final positioning" for those amps, I'm sure he would've just already screwed them in but you want to nit-pick every detail. no damaged karma I'm not trolling. some people cant handle the real truth. I can tell by your defense that you already realize what I'm saying is true and your torturing the poor install guy. this is a simple install, your not really fabricating anything custom, its a hu, amps, proc and sub. but I'm sure he's spending a lot more time dealing with you than necessary.
