Does anyone have any experience replacing just the stock sub, and leaving the factory amp intact? Or, would someone recommend replacing the stock sub, as well as an amp to power it? Also, has anyone thought about using the trunk in a free air enclosure as opposed to creating a sealed box for a replacement?
