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.

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.

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.

CTA-2006 Compliant

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

Punch EQ2

A midbass hump between 100-275Hz A steep roll-off of high frequencies from 2kHz up to 20kHz Reduced bass response below 50Hz The Punch EQ on-board equalization circuit helps correct for these acoustical deficiencies in the listening environment. When set to Low-Pass(LP) operation, it becomes a variable Bass Boost. When set to High-Pass (HP) operation, it acts as a variable Mid-Bass and Treble Boost. When set to All Pass (AP) operation, both Bass and Treble frequencies are boosted.">Onboard equalizer with up to +18dB @ 45Hz and/or up to +12dB boost at 12kHz.

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.

TO-247 MOSFETs

60 % more surface tab area for increased cooling Larger Mosfets for extreme power handling capability and output power Less heat = more reliability 40 Mosfets in T30001bd! ">(left-OLD right-NEW)
Rockford Fosgate amps use custom TO-247 MOSFETs. These have 60% more metal tab area for more power capacity, lower impedance and improved heat dissipation over traditional TO-220 MOSFETs found in competitor amps.

The Power T400-2 is a 2-channel amplifier capable of producing 200 Watts into each channel at 2-Ohms. The T400-2 is so powerful it can easily drive multiple component systems or multiple subwoofers in bridged/mono mode.
The T400-2 is " One of the most impressive amps I've ever seen. " says Sergey of K&B Audio. Don't let its size fool you ... this all MOSFET amp packs enough power to run one 2-Ohm DVC or two 4-Ohm DVC subwoofers with ease and its dual function EQ can tune-in any pair of high frequency component speakers to deliver premium sound quality. " The amplifier is without a doubt the most efficient Class A/B amplifier I've ever tested. "

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.
