oh yes for sure! planning on cutting a hole to slide up and down when i need to remove the aftermarket amp and reinstall the oem amp for dealer visits. |
I have both installed with a custom harness. Don't think the vendor is still offering them but maybe your audio shop can do it for you. Just a BMW connector with some wires pinned into it. I have the diagram somewhere. I literally ha e the stock one attached with spacers and Velcro on top of the Match, then it's all wired together so both amps are installed and get power all the time.
Stock is only used for CAN-BUS nothing else.
