not too hard to out service them, they like to reccomend lightning audio and not the higher end stuff the fast and ferious stuff. the sales might take a little while to get comming but im sure i can get everyone as a repeat or close to it.
sounds good just remember that not every customer is going to be a custom install some people just want to change a head unit or speakers....you have to sell to the masses to be able to afford to put the time and labor into the custom work...good luck
ya i know most wont get the custom work but i think there will be more than there should be just because they have never had the option before unless they want to drive for 4 hours to get it done.
