Aftermarket Radio Install With Oem Amp

[DNice]

Hi all, I just bought an aftermarket radio for my 1997 es300. I installed the conversion kit and the harness from installers.com. My radio is really low in sound. Do I have to hook the factory amp up to the aftermarket radio separately? If so, what do I need to make it happen?

Did you ever figure out about this. Needing to do same on 97 es300 that I just picked up last week as stock radio and salvage purchase is dead.
