Can you recover your speakers if they were just sitting in the trunk of your repossessed car in Colorado?
You should verify this for your particular state, but in general
a company or bank may repossess a vehicle only. Any personal items
left in the car still belong to the owner. If you are denied access
to your personal property, you can contact the police and file a
theft report or you can sue for damages. If the speakers are not
part of the car, any and all property should be able to be claimed
by the owner.
