I bought a Alpine CDA-9855 today and was trying to get the Best Buy mobile install guys to install it. Well all sorts of problems went on and to say the least they just can't figure out how to hook it up with the stock wiring, stock speakers because of the amps. I understand that I'll probably have to bypass the amps, but they want me to replace all of my speakers and run new speaker wire. Does this sound right? Do you have any information I can give these guys so I can get this working
