I just finished replacing the original Infinity door speakers in my wife's 2002 Liberty Limited with Polk DB651s speakers and thought I would post how I handled the speaker connections and mounting the amplifier.
We started with the rear speakers since I figured those would be easier as I had read about the amplifier mounted on the front ones. The rear speakers appeared to actually be in good shape with foam surround intact. The new speakers came with a mounting adapter but unfortunately the 2002 is an oddball on the speaker connector so there is no wiring adapter. Turns out the male connector on the speaker just unclipped after I unsoldered the wires going to the speaker itself (see pictures). I then soldered a short length of the speaker cable that had the right connecters for the new speaker to the Infinity connector and made my own adapter. Unfortunately I didn't take a picture of the finished result for the rears.
For the front speakers, the foam was shot on both with nothing left so no wonder they sounded terrible. The amplifier is bolted to the speaker and a hardwired cable goes from the amplifier to the speaker with the factory setup. I ended up mounting the amplifier just below the speaker opening after drilling 2 holes with some 10-24 x 1 1/2" stainless steel bolts, washers and nyloc nuts that I picked up from Lowes. The front speakers don't use a plastic connector like the rear and the board is riveted to the speaker but I was able to use a pair of needle nose pliers to get the lug on each side free by twisting after unsoldering the wires going to the speaker. I again soldered a short length of speaker wire that had the right connectors for the new speakers to these lugs and made short extension cables to go from the amplifier to the speaker (see picture). I just had to use electrical tape to cover the lugs and connector on the amplifier side.
Hopefully this helps someone else.
