The Nexus Audio Systems C-816 is fully guaranteed against all defects in materials and workmanship for two (2) years from the date of purchase. During this period, Nexus Audio Systems will replace any defective parts and correct any defect in workmanship without charge for either parts or labor. For this warranty to apply, the unit must be installed and used according to its written instructions. If service is necessary, it must be performed by Nexus Audio Systems and/or an authorized distributor. The unit must be returned to Nexus Audio Systems and/or an authorized distributor at the owner's expense and with prior written permission. Accidental damage and shipping damage are not considered defects, nor is damage resulting from abuse or from servicing by an agency or person not specifically authorized in writing by Nexus Audio Systems and/or an authorized distributor. This Warranty does not cover:
  • Damage caused by abuse, accident, misuse, negligence, or improper installation or operation
  • Power surges and lightning strikes

Nexus Audio Systems sells products only through authorized Distributors to ensure that customers obtain proper support and service. Any Nexus Audio Systems product purchased from an unauthorized dealer or other source, including retailers, mail order sellers and online sellers will not be honored or serviced under existing Nexus Audio Systems warranty policy. Any sale of products by an unauthorized source or other manner not authorized by Nexus Audio Systems shall void the warranty on the applicable product. Damage to or destruction of components due to application of excessive power voids the warranty on those parts. In these cases, repairs will be made on the basis of the retail value of the parts and labor. To return for repairs, the unit must be shipped to Nexus Audio Systems at the owner's expense, along with a note explaining the nature of service required. Be sure to pack the unit in a corrugated container with at least three (3) inches of resilient material to protect the unit from damage in transit.
