    Eric, your 1993 Infiniti G20 may have a factory amplifier that needs to be turned on by your after market radio. The car stereo amplifier trigger wire has to be wired up to turn on your factory amplifier. Unfortunately, we do not have this information but maybe someone from the Modified Life community can post that information here. Hope this helps. Good luck with your 1993 Infiniti G20 stereo installation.
