CTA-2006 Compliant

Answer ID #199 in our Knowledge Base .">Power ratings on Rockford Fosgate amplifiers conform to CEA-2006 industry standards. These guidelines mean your amplifier's output power ratings are REAL POWER numbers, not inflated marketing ratings.

Image Feature

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).

TRANS ana

Simplifies signal path Greater reliability Exceptional sound quality ">Trans ana is a Class A/B topology that simplifies the signal path of the amplifier allowing the signal to travel through the amplifier at a lower voltage. The result is greater reliability and exceptional sound quality.

Image Feature

DTM

Heat is often inefficiently dissipated across a heatsink causing "hot spots". This impacts important design goals, which are: Keeping internal components cool. Maximizing potential of all components. Reducing distortion for better sound quality. Increasing efficiency to produce more power. ">Dynamic Thermal Management evenly distributes excess heat across entire amplifier heatsink.

Image Feature

Balanced Differential Inputs

Differential inputs eliminate noise picked up by signal cables.

DSM

DSM utilize 1% tight-tolerances improving efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature.

Image Feature

MEHSA 3

3 (Maximum Efficiency Heat Sink Application - gen. 3) is a proprietary process that yields up to five times better heat transfer than traditional FET mounting techniques, using the exact same components. A multi-layer insulated metal substrate operating with minimal thermal resistance spreads heat both downward & outward to quickly dissipate heat from each device across the heatsink. This process combined with our optimized heatsink designs, DSM (Discrete Surface Mount) technology and MOSFET devices, allows Rockford Fosgate to squeeze more watts per cubic inch from every output device as well as provide consistent thermal stability. The 3rd generation creates a dielectric layer between the ceramic topside and the aluminum base that retains all of the electrical isolation and capacitive coupling of the original MEHSA material increasing it's thermal conductivity. The higher power handling results in a 20% reduction in thermal impedance. ">MEHSA 3 reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span.

Image Feature

NOMAD

The NOMAD circuit accomplishes just that. It's a totally new and very high tech method of dealing with device current and voltage parameters, without being affected by other factors such as heat. Our approach to "real time" protection is one that uses a mathematical transformation which eliminates the problems encountered with trying to do real time multiplication of instantaneous device voltage and current. Essentially an analog computer calculates at each instant, the maximum allowable level of safe current for each output device, based on their instantaneous voltage drop. This allows the protection to be much more precise than ever before, and ensures reliability.">NOMAD is a "real time" analog computer that protects your amplifier from shorting speaker wires and dangerously low speaker impedances.

The Punch P400X2 is a 2-channel stereo amplifier capable of producing 200 Watts into each channel at 2-Ohms. The P400X2 amplifier is great with full-range or component systems or can be bridged for use with 2 or more subwoofers.
Whether you're looking to drive high frequency component speakers or low frequency subwoofers, the P400X2 has the power and flexibility you need to put some serious PUNCH in your vehicle. The power available from such a small amp means it's a great match for a 2-ohm DVC subwoofer or pair of 8-ohm SVC subwoofers.

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.
