i work at shop that sells JVC,Memphis, Sony, Dual,Clarion, Audiobahn, Alpine,Pioneer......Its **** hard to sell Alpine over Dual, especially when your customers want Boss and Crunch and Power Acoustik......(plus my Boss doesn't want to invest money in good quality products) You've gotta sell what you can sell. I know myself that I dont know half the things I need to, but I'm learing with the help of this forum and my MECP books I'm getting there. I dont have to worry about people coming in asking me what the "best" sq deck I have. All they ask is "What the best sub is" F*cking Dumba$ses
