amplifiers on the market and of course at a reasonable price. You will be amazed at the quality and power that these new amps offer.  

We have spared no expense in designing these amplifiers, creating the most rugged, reliable, powerful and best performing amplifiers. In fact we 
are so sure of the quality we backup every dB Series amplifier with one year warranty which exemplifies our commitment to the end user. (See 
enclosed warranty card for details.) 

Please read this installation guide carefully for proper use of your dB Series amplifier. Read this entire guide fully before attempting your installation. 

WARNING:

 BE AWARE!

 

Use of this amplifier at extreme high volumes for extended periods of time may cause hearing loss and or 

hearing damage. During periods of prolonged high volume levels it is recommended that you use ear safety devices. Your ability to hear 
necessary traffic sounds will be impaired. While driving always keep your sound volume at reasonable levels. We at Rockville want you 
listening for many years to come. 

• When installing the amplifier, secure it tightly. An unmounted amplifier in your car can cause serious injury to passengers and damage to your 

   vehicle if it is set in motion by an abrupt driving maneuver or short stop.
• To reduce risk of electric shock, never open the unit. There are no user serviceable parts, refer service to an authorized Rockville service center.
• Do not expose this unit to any kind of moisture. 
• Please ensure that the unit is situated in a properly ventilated area.
