I want to install an aftermarket amplifier and subwoofers in my 1998 Lexus es300, and also keep the standard head unit, amp, and subwoofer. What wiring harness and other components would I need to accomplish this?

I would first suggest losing the factory head unit. It's not that hard to replace. If you're worried about looks, the improvement in sound will outweigh the loss of factory look. In my opinion, of course...

Why keep the factory subwoofer?? Virtually any reasonably good quality aftermarket setup will sound better and overpower it anyway.

I want to keep it because I am selling the car in a few months, but I picked up this system in an auto salvage yard. I want to put it in to test it, but I am going to wait on the aftermarket head unit. I just want to keep the stock headunit so I don't have to install a new one just to turn around and replace it. I just need to know where to find a wiring harness that will accomplish my goal.
