I have a 98 T/A Convertible with the standard or stock Stereo that looks like a Monsoon but isn't. If I buy a used Monsoon Head unit and amp (if I can find one), will it just plug in, or is there more to it? Is the amp in the trunk for the Monsoon cars, and do the non Monsoon cars have the wiring any way? My stock units LED's are going out. Thanks, Jeff
