I have a stock amplifier that came off of a 96 328is. I do not know much about it, when i bought my car it was already removed because the previous owner put a new system in the car. If anyone needs one let me know.

I just took three and sent them to my email using my cell phone. I only got one of them from my email i guess i have to send them individually. I think i attached the first one. If you need more views i have the top and the label (up close) on my phone i can send to my email again for you.
