I have a 96gm as well and i went thru the same thing. Basically, when you decide to install an after market stereo the existing amp is no longer useful. The unit in the trunk is an amp/tuner so once you unlpug the tape player its useless. Essentially you have to run rca/power/keyed power to another amp for rear or box speakers and run your front doors off the new deck. Or run your rear deck speakers off your stereo
