EXTENDED WARRANTY

This amplifier qualifies for a FREE one-year extended warranty when you buy the correctly matched Rockford Fosgate Amplifier Installation Kit.

How it Works
We want you to get the performance and reliability that Rockford Fosgate Amplifiers are famous for. Using poor-quality (under-spec) wiring is a guaranteed way to get less than you paid for from your system.

We are so certain that getting your system wired to rock with the right wire and cables will make a difference, that we will give you an additional (1) year warranty on your amp when you use the matching amplifier installation kit.

One (1) warranty extension per amplifier regardless of the number of amplifier installation kits purchased.

What To Do
Cut the UPC code off the amplifier installation kit package. Attach it to your amplifier PVC (Performance Verification Certificate). There is nothing to send in or register. If your amplifier requires service during the extended warranty period, simply return it with the original PVC and amplifier kit UPC to your authorized Rockford Fosgate dealer. Contact Rockford Fosgate customer support for assistance.
