You have MOST security on your Volvo. They turn off amplifier after 5 sec. You need to add new amplifier into the system (codding work only for amplifier which you are add) or you need to take out MOST security from your Volvo. Than you will be able for change all MOST elements without programming/codding they into the car (of course if your volvo work with this model). So for example you can't change single CD into 6-CD changer, but you can change CD player into new one without codding they If yours old was day.
Changing amplifier doesn't give you bigger control on they. If you want to have more sound control options into the menu you need to change software into High Performace or Premium Sound.
