Ok just a few things. You say go with 6.5 for the fronts and leave the factory wiring, but it needs an adapter. Do you know where I can get this. Next is putting the sub behind my seat a good place. I have the 2004 Touring with the bose system. ALSO THIS IS THE BIG QUESTION. I HAVE OWNED MANY CARS THAT CAME WITH A STOCK BOSE SYSTEM AND IN PAST EXP. I HAVE NOTICED THAT BOSE SYSTEMS PUT ON MINI AMPS. ON THE BACK OF THE SPEAKERS SO IF YOU WANT TO JUST UPGRADE YOUR SPEAKERS FIRST YOU HAVE TO CUT WIRES INSTEAD OF PLUG AND PLAY ADAPTERS FROM YOUR STOCK WIRES TO YOUR NEW AFTERMARKET SPEAKERS. Also where is the satilite radio n-bus hook up on the touring model. Is it behind the deck?
Thanks
