How much it cost for a new AMP installed?

Ooops, almost tap it on the white wire where i tap the speakers, i will do this by saturday. Yes mine was a 2 connectors gray and black, so the 10 pin where i have to tap on it.
Im also fixing my wirings again so every time i need a space at the back i could just pull the wires instead of inlockng them from the amp. I will take a pix for better understanding. Got a new Aux input too so thats another set of Learning the X5.
This is a great site and saves a lot of $$$$, dealers are so bad that they think you have all the money coz you have a beemer. My uncle works at ford service dept and a lot of crazzy things he share. And BMW service is just the same. This is better learning and knowing what we can do for our car.
Oh well back too work to pay the dues$$$$$
