If taking DIY approach, you will receive a Sierra-2 product label but we will not include a new serial number since we can not re-certify the speakers. For the DIY upgrade kit, the warranty on the speakers will not reset and the components will be covered for manufacturing defects only.
Hope this makes sense.
