I just purchased a 2002 Maxima and would like to add a nice sound system to the car. With the car being so new to me I don't like to remove things without knowing what to do. This may sound stupid but how do I get that damn dash cover off to get to the stereo??!! lol. Now what I'm thinking of doing is putting in an aftermarket head-unit, while using the bose door speakers and adding my own sub box. I'm aware that I need the adapter for the Bose setup. So I have the subs, head-unit, and plan on buying the aftermarket dash-kit and the adapter. Do I need the wire harness also if I'm getting the adapter? FINALLY, can I use my 4-channel amp with the Bose speakers or will they be powered heavily enough to roll with thumpin subs? And if anybody doesn't mind explaining the process for the whole thing it would help too. Sorry for the long post, but if anybody is willing to help I would greatly appreciate it. Thanks.
