LIMITED WARRANTY - AMPLIFIERS (USA)

JL AUDIO warrants this product to be free of defects in materials and workmanship for a  

period of two (2) years. The warranty is extended to three (3) years total if installation is performed by an 
authorized JL Audio dealer using a JL Audio Premium Power Connection System for power wiring.

This warranty is not transferrable and applies only to the original purchaser from an authorized  

JL AUDIO dealer. Should service be necessary under this warranty for any reason due to manufacturing 
defect or malfunction, JL AUDIO will (at its discretion), repair or replace the defective product with new 
or remanufactured product at no charge. Damage caused by the following is not covered under warranty: 
accident, misuse, abuse,  product modification or neglect, failure to follow installation instructions, 
unauthorized repair attempts, misrepresentations by the seller. This warranty does not cover incidental 
or consequential damages and does not cover the cost of removing or reinstalling the unit(s). Cosmetic 
damage due to accident or normal wear and tear is not covered under warranty. 
 

Warranty is void if the product’s serial number has been removed or defaced. 

Any applicable implied warranties are limited in duration to the period of the express warranty as 

provided herein beginning with the date of the original purchase at retail, and no warranties, whether 
express or implied, shall apply to this product thereafter. Some states do not allow limitations on implied 
warranties, therefore these exclusions may not apply to you. This warranty gives you specific legal rights, 
and you may also have other rights which vary from state to state.

If you need service on your JL AUDIO product:

All warranty returns should be sent to JL AUDIO ’s Amplifier Service Facility freight-prepaid through 

an authorized JL AUDIO dealer and must be accompanied by proof of purchase (a copy of the original 
sales receipt). Direct returns from consumers or non-authorized dealers will be refused unless specifically 
authorized by JL AUDIO with a valid return authorization number.

Warranty expiration on products returned without proof of purchase will be determined from the 

manufacturing date code. Coverage may be invalidated as this date is previous to purchase date. Non-
defective items received will be returned freight-collect. Customer is responsible for shipping charges and 
insurance in sending the product to JL AUDIO. Freight damage on returns is not covered under warranty.
