Near as I can tell from your cryptic style of English, your Acadia is not running and is throwing trouble codes.

What are the codes?

My understanding of "B2aaa" is it means you are using an incompatible scan tool. Which would make be question the validity of your other codes.

What prompted you to replace the ECM?

 

[creasonmelinda2022]

I redone the codes again it's saying a crankshift sensor and a fuel injection cylinder 6

If you add a large AMP you have to run the proper gauge wire, and the battery is in front of the seat on the right. The alternators in these vehicles are funny, and I have had mine shut down completely like the battery was dead, only to find out it goes into a battery save mode so it won't run down. Wait 15 and it starts right back. So many electronics on these vehicles. But back to your amp, the old saying is you can't run a river through a straw, so you have to be sure you have the amp wired right, and it was a BOSE system, it already had an amp.
