Im purchasing a d3 in about a week that is 6 months old. It comes with a 3 year warranty, ipod adapter and remote. I think I am going to try and tackle the install myself. I have been on here doing research etc. This will be my first H/U install so I am pretty nervous about it. I have an 04 Yukon with onstar and bose. I have an alpine aftermarket amp with two Type e12 subs. Is this going to cause any problems over a stock bose setup? Could someone tell me all the parts I am going to need for my setup? It is going to come with the onstar and bose module but that is it. Thanks for all the help y
