Went to the Chrysler dealer that has been servicing my Xfire and has Xfire mechanics. They told me that the speaker behind the driver side that I need is no longer available but the passenger side speaker is. Unfortunately the driver side has the sub woofer. They use an independent company that installs upgraded sound systems for their vehicles and I was later told that it would cost me $1,300.00 to get the job done with a separate sub woofer installed who knows where. Imfink2 says he bought a Kicker 43CWRT672 and I had previously found a Kicker speaker on line for $74.99 that was the 671 model. I will check with the auto stereo specialist tomorrow to see what he suggests. Any way you cut it, it will be expensive.
