Hello and welcome to JustAnswer!
There are many things that could be going on but the compressor not engaging is almost surely not related to an aftermarket radio being installed.
The control head controls the compressor clutch relay based on driver input after verifying pressure is ok using the pressure sensor and the clutch cycling switch. The problem could be the control head, compressor clutch, the relay, wiring, the pressure sensor or cycling switch, or it could be a charge issue. The most common cause of a compressor not engaging is low charge.
What parts have been replaced and were they new or used?
