    I found the wiring diagram for my lexus gs300 on your site but I am having trouble getting the stereo to work and I think it is because it has the nakamichi system with the amp. The car is a lexus gs300 1995 and if anyone has any ideas for me I would really appreciate an email with the info. the stereo lights up and functions but I don’t have any sound. let me know, Thanks

    Ben, your 1993 Lexus GS300 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.

    The rear door speakers are also 4″, you have stated 5″ on your diagram.

    anybody know how to get the built in sub to work with an aftermarket deck?

    My 1993 Lexus GS300 front passenger side door speakers aren’t working and my sub wont turn on. Could it be the factory amp. everything else is working great.

    Charles, first double check ALL your fuses and make sure ALL your fuses are good. You can do this by using an Automotive Fuse Tester and making sure all of your fuses are not blown. If all of your fuses are good, your 1993 Lexus GS300 may have a factory amp that needs to be turned on by your after market radio. The car radio amplifier trigger wire has to be wired up to turn on your factory amplifier to output sound from your speakers. Double check that your 1993 Lexus GS300 amp turn on wire is connected. Hope this helps. Good luck with your 1993 Lexus GS300 stereo installation.
