(1) year from the original date of purchase. 

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,

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

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-
