You have their name on YOUR windshield! They should have done the isolator or fixed whatever problems you had for free! Your advertising for them! Talk to the owner, if I were in his shoes seeing a quality system (not just a bunch of stuff randomly fitted together) in a vehicle that left my shop I'd be wanting the people as happy as they could be. It's another story when you have a set of used 6.5's in one door, 6x9's in the rear from another car with a old sony radio yanked from a beater all bunched together with lanzar and pyle amps. It isn't the case with what you have going on and from what I can see you'd be doing the company positive business and advertisement by showing off the car especially with their name paste to the window. IMO I'd want them to do something about that top kicker plate which kind of does look a bit off. That 6x9 box should have been attached a bit better even if you were to get into a 20mph accident I'd be wanting to make sure that box was going to stay if it were leaving my establishment. Don't be a cock as that never works until you have to be, by talking to the owner I'm sure you'll be taken care of. BTW wait to take the stickers off! LOL
