Didn't think the connections for speakers would be that way
 

I bought 2 pairs of infinity 6002i and am attempting to put them in at the moment. I notice that the connection between the wires and the speaker aren't the same from the factory ones. The factory ones have a plastic plug that let you plug the wires directly to the speaker but with the new speakers, they seperate the + and - pole. So my questions are, do I just remove the plug by pulling (or just cutting the wires) and then reconnect to new speakers? And do I need to solder the wires to the speakers?

you can buy speaker adapters at CC or just cut the wires and splice them. or you can run all new speaker wire.

Ok, it's done but now, I have another problem...I dunno how to put the grill on the rear deck... The speakers came with a lil bag with screws but don't know which to use for the grill so if anybody can help, it would be cool

just leave the stock grills....it dosnt let people know you have expensive speakers back there and really dosnt make a differnce, if you do want to swap them though the stock grills have little screws underneath them, just take the peice off and pop the grills off and put yours on with the supplied hardware

:sprint:

i kept my stock grill too after i changed my rear speakers out

mine almost looks stock as a rock. with the exception of tweaters in the door
