The refoaming my have worked, basically the outer rings had come off and the cone had torn at the edge.
I do have the infinitys which was a bit of a surprise to find the amp fastened to the speaker.
I actually went to best buy (they were really knowledgable and helpful a few weeks ago when i was wiring up a combined cb/am/fm antenna on my wrangler so thought they could have a bit more business) and got a set of pioneer 6.5" speakers and adaptors to fit them into the chrysler fixing pattern.
In hindsight the adaptors werent need as you can cut the old speakers up and use the outer rim as an adaptor. I spent some time grinding the inside of the adaptors i bought to fit the speaker on the inside near the door metal, having fitted the door cards back on i think there is room for them to go on the outside, there is alot of clearance.
I unscrewed the amps off the old speakers, drilled a couple of holes in the door below the speaker hole and ziptied the amp to the door.
Then extended the wires from the amp to the speaker using the wires that came with the new speakers, hooked them up, tested them and then ran the windows up and down to check for clearance.
