WTB: 06 or equivalent 3g TL OEM amplifier

So, I bought an 06 TL from a buddy who had an aftermarket stereo system in place and we just switched from his stuff to mine upon my purchase. He provided me with all the factory parts as well, or so he thought. I sold the car to my mother-in-law and when I went to put the factory goods back in it, I realized there was no amp.

If you have one, please let me know via PM or response right here.

Thanks guys!
