$150.00 for the Audio control unit and you will be able to hook up a dedicated sub amp and a four channel amp for the rest of the speakers with zero issues. The unit also senses power to the speakers and has a remote on for the amps. Run your 12+ power from the battery, find a good ground in the trunk and go from there.
After some research today I have found out the ACM (audio control module) has the extra sub ports used for the trunk subs on the Shaker 1000 system. I have also found out that the said sub ports are inactive on the shaker 500 system. So are you saying that a new ACM with the shaker 1000 ports activated costs $150, or it would cost $150 to have a dealer activate the sub ports on the ACM that I already have in the car?
Thanks for the info.
