Rockford was first founded by Jim Fosgate in 1973 as FosgateElectronics(Fosgate later renamed as Rockford Fosgate according to the street where its headquarters is located. Jim, the founder, took the lead in using Mosfet oxide material technology in the power amplifier heat dissipation of car audio, and invented the equalizer technology called "frequency exciter" to compensate the sound quality defects of car audio. Today, this invention is widely used in the Power amplifier products of Prime, Punch and Power series of Laifu.
The most famous products of p>RockfordFosgate car audio are power amplifier and woofer. Its car power amplifier with several patents has won the Green Pitch Award for more than 1 years in a row, and its technology is far ahead in the global car audio industry. At present, no other manufacturer can copy the superior performance, accuracy and high reliability provided by Rockford Fosgate products. Rockford Fosgate "Laifu", a world leader in the design and production of professional HI-END car audio, continues to occupy the dominant position in the car audio industry with the advantage of no competition. Laifu Company was founded in 198. In its early years, it conquered almost all the speakers in the world because of a car amplifier called PUNCH Circuit, and was enthusiastically sought after by car audio enthusiasts. In 1999, it became the first listed company in the car audio industry. For more than 2 years, Laifu Company has become a well-deserved overlord in the world car audio industry by merging many well-known enterprises in related fields.
Laifu's most famous products are power amplifiers and woofers. Its automotive power amplifiers with several patents have won the Green Pitch Award for more than 1 years in a row, and its technology is far ahead in the global automotive audio industry.
Laifu's products have been the top seller in the middle and high-end car audio market in the United States for many years.

In the world automobile kingdom-the United States, the name of Rockford Fosgate is as household name as Coca-Cola;
Rockford Fosgate represents not only a brand, but also a passionate lifestyle and culture. Since the 197s, Mr. JIM FOSGATE brought Fufu products into the world, and Laifu has started its remarkable journey. In 1973, JIM FOSGATE designed a power amplifier with a HEADROOM and an equalization circuit called PUNCH. This circuit compensates the low frequency and high frequency with 4dB per octave, thus achieving a smooth response in the car. Since then, the car audio has entered a new realm. The newly launched Laifu amplifier is so powerful that it almost destroyed all the speakers on the market. In order to match the PUNCH amplifier, ROCKFORD Company began to entrust CARBONNEAU, a qualified old factory with more than 5 years of history, to tailor professional car speakers for Laifu amplifier, and the car audio began to become perfect. In 1987, Laifu merged with the world-famous DAVID HAFLER company, so Laifu also occupied the market at a high starting point in the field of household and professional audio. In 1998, Laifu merged with LIGHTNING AUDIO, a famous brand in the automobile audio accessories industry, and its entire line of products, including auxiliary capacitors, wires and mounting parts, was completely improved. In 1999, Laifu became the first listed company in the car audio category, with an annual turnover exceeding 1 million US dollars. In 21, Laifu once again acquired the famous Q-LOGIC company in the United States and MB-Quart company, which is famous in the international audio industry. Laifu's professional and multi-level product structure is more perfect. In the market share of professional car amplifiers and professional car horns, Laifu has been ranked first in the industry for many years. In the late 198s, Laifu began its international journey. The trip to Europe is the first stop of Laifu's international journey. Laifu, which is based in Germany, is responsible for the operation and support of Laifu Europe. With wide welcome and full praise, Laifu swaggered into South America, Australia and Asia. Laifu products have spread all over the world in more than 7 countries and regions, and more than 18 agents and service outlets are shouldering the world mission of Laifu, delivering the most beautiful gospel to every outstanding ear in the world. Laifu has settled in Japan, Taiwan Province, Singapore, South Korea, Thailand, Indonesia and other places. In 1991, Laifu came to Hong Kong, which attracted worldwide attention. In 1993, Laifu firmly settled in Chinese mainland, and established Laifu service bases in Guangzhou, Shanghai, Beijing, Chengdu and Wuhan through the promotion of Shanghai Miaosheng Technology Co., Ltd. As a pioneer of domestic car audio, Shanghai Miaosheng Technology Co., Ltd. first brought the top brands to China. Rockford Fosgate is famous as the leader of high-performance car audio, which is attributed to the technological reform. ROCKFORD has many revolutionary technology patents and has been leading the technical development direction of the industry.
2 Trans.nova (transconductance node voltage amplification circuit): allows audio signals to pass through the preamplifier with extremely low voltage. The circuit can make the signal reject the problem of poor sound quality caused by temperature fluctuation and crosstalk. TRANSNOVA said: You don't have to worry about anything but calm down. (U.S. Pat. No.4,467,288)
Trans. ana: Similar to the philosophy of TRANS．NOVA, that is, short signal path and low voltage are used in the pre-stage so that the amplifier can output the cleanest music signal.
3 TOPAZ (track operation driver stage amplification area): minimize the grounding problem of the main body and help ensure perfect sound quality. TOPAZ circuit actually creates a grounded isolation band, which completely eliminates the noise or voltage spike between the output of CD player and the input of amplifier. TOPAZ allows you to use any CD player or host in the market with confidence, because TOPAZ improves the insulation between the input terminal and the power ground to 3-4dB. TOPAZ= murmur. (U.S. Pat. No.5,751,823)
4 InGO patented technology: No matter how bad the battery is, the power supply will be adjusted with the battery voltage to ensure the rated power output. The INDGO line enables PUNCH to expand its function and output high power, which is why ROCKFORD power always sounds stronger than other power amplifiers.
5 MESHA patented technology: the heat generated by the power amplifier can be transferred through the rapid heat dissipation of internal components and the heat sink on the surface. This power solution, combined with DSM technology and MOSFET components, enables ROCKFORD engineers to squeeze more power from each unit volume and each output device. On the one hand, the optimization of power output increases the stability of temperature, and at the same time, it also makes the equipment get the maximum reliability.
patented technology of p>6 NOMAD (non-multiplicative advanced judgment circuit): the intelligent NOMAD circuit makes a more ideal application to the vehicle electrical system. Have you ever heard of the thinking amplifier? Will you think further about the power amplifier? All Laifu power amplifiers have protection systems that can be further considered. Music is dynamic, from surging and shocking to whispering, so the power amplifier must also be dynamic and can faithfully transmit power immediately before it is needed. Lucky Power Amplifiers all adopt NOMAD system to safely transmit extra horsepower, directly from the alternator to your amplifier.
