[V8] Aftermarket stereo/5speed

[toml99 at todomundo.com]

So, I got the Alpine deck out this morning(stereo guy did, as I  
didn't have the removal tool), and there was no "interface/OEM amp  
adapter" box.  The original connectors have been removed, and  
everything's crimped.  At this point, since the front's are failing/ 
rears are lacking amps, I'm thinking of putting 2 new 4" speakers in  
the front boxes, and hooking them directly to the stereo.  There are  
4 wires in the connector.  Might I only need 2 of them(source/ 
ground)?  I like good sound, but am half deaf, and just want a stereo  
that works.  I was hoping not to run new wire, and will leave the  
rears for now, as they sound fine(till I get the new ones in the  
doors)....The stereo is 18WattsRMSX4 and I'm not a full blast kind of  
guy.....Do I need to run speaker wire.....was hoping for a quick/ 
dirty install as I'm too busy to run wire/figure out the bundle in  
dash/too broke to pay stereo guy...........Any BTDT...Tom
