POWERBASS AUTOSOUND LIMITED WARRANTY POLICY

PowerBass USA, Inc. offers limited warranty on PowerBass products under normal use on the following terms:

PowerBass Autosound Speakers are to be free of defects in material and workmanship for a 
period of one (1) year.

This warranty applies only to PowerBass products sold to consumers by Authorized PowerBass Dealers in the United States 
of America.  Products purchased by consumers from a PowerBass dealer in another country are covered only by that coun-
try’s Distributor and not by PowerBass USA.

This warranty covers only the original purchaser of PowerBass product.  In order to receive service, the purchaser must 
provide PowerBass with a valid purchase receipt from an authorized reseller stating the consumer name, dealer, product 
and date of purchase.

Products found to be defective during the warranty period will be repaired or replaced (with a product deemed to be equiva-
lent) at PowerBass’s discretion and will not be liable for incidental or consequential damages. PowerBass will not warranty 
this product under the following situations:

 

• Speakers received with bent frames or water damage

 

• Abuse such as holes in the cone, surround or ripped spider

 

• Voice coil damage due to amplifier clipping or distortion

 

• Product that has not been installed according to this owners manual

Any implied warranties including warranties of fitness for use and merchantability are limited in duration to the period of 
the express warranty set forth above.  Some states do not allow limitations on the length of an implied warranty, so this 
limitation may not apply.  No person is authorized to assume for PowerBass any other liability in connection with the sale 
of this product.

Please call (909) 923-3868 for PowerBass Customer Service.

  You must obtain an RA# (Return Authorization Number) 

to return any product to PowerBass. 

The RA number must be prominently marked on the outside of the shipping 

carton or the delivery will be refused.

  Please pack your return carefully; we are not responsible for items damaged in 

shipping.  Return the defective product along with a copy of the original dated retail sales receipt, plus $12.00 for handling 
and diagnostic evaluation to:

PowerBass USA, Inc., 
Attn: Returns (RA#__________)
