CE Compliant

It proves to the authorities, but also to the buyer -or user- that this product fulfills all essential safety and environmental requirements as they are defined in the so-called European Directives. The ce marking directive (93/68/EEC) was adopted on 07-22-1993 and updated as 768/2008 EC on 13-8-2008. The directive gives a detailed description of the initials CE and any other marks specific to a particular directive and the many ways conformity may be acquired. In return for fulfilling the CE marking requirements, the manufacturer or its agent gets the permission to cover the entire European market using only one approval procedure for the topics covered in the applicable directives. No member state of the European Community can refuse trade of any (electronic or electrical) product that has been CE marked (unless fraud suspected). For some products however, national regulations exist, as long as the requirements covered in these national regulations are not covered by a pan-European Directive. ">This product fulfills all essential safety and environmental requirements as defined in the European Directives (768/2008 EC).

3-Stage Airflow

Compact Rockford Fosgate Power BR and AD amplifiers generate a lot of wattage in a compact chassis. A natural by-product of generating this power is heat. To get rid of this heat, Rockford Fosgate engineers developed an efficient method to keep the amplifier running cool. This is accomplished by using a 3-stage thermal lock extrusion. It uses "dual fan forced induction" to pull in fresh air. It pulls heat off the MOSFETS and directs airflow into the exhaust channel. Then finally drives this heat out of the amplifier. Furthermore, the top heat sink is decoupled from the bottom, so the top remains cooler to the touch. SUMMARY When installing the amplifier, it's best to allow 2 to 3 inches minimum clearance around the fan intake and exhaust vents to optimize air-flow. As you can see, this method developed by Rockford Fosgate engineers, effectively exhausts heat and ensures your amplifier runs cooler for optimum performance.

Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
