    ECHNICAL ESIGN Many of the solutions to common design problems encountered by Rockford Fosgate engineers created entire new circuit designs as well as new ways to construct the Punch 250. was spared in design and construction from the unique circuitry design to the manufacturing process that has proven to be the industry reference for many years.

    The DSM (Discrete Surface Mount) manufacturing process combines the advantages of both discrete components and integrated circuitry. Rockford Fosgate is the only American amplifier manufacturer to have invested millions into this process. DSM components differ from conventional discrete components in different ways. They are more compact, more rugged, and they efficiently dissipate generated heat.

    (Metal Oxide Semiconductor Field Effect Transistor) Rockford Fosgate is one of the few manufacturers in any of the sound communities to utilize MOSFET devices in both the power supply and the output stages . MOSFET (Metal Oxide Semiconductor Field Effect Transistor) devices offer several important inherent advantages over the 30 year old technology of bi-polar design.

    NSTALLATION ONSIDERATIONS Tools Needed The following is a list of tools you will need for installing the “250 Series” Power amplifiers: Allen wrenches 9/64" & 3/32" (included) Wire strippers Battery post wrench Electric hand drill and assorted bits This section focuses on some of the vehicle considerations for installing your new Punch amplifier. Checking your battery and present sound system, as well as pre-planning your system layout and best wiring routes will save installation time.

    IRING YSTEM CAUTION: Avoid running power wires near the low level input cables, antenna, power leads, sensitive equipment or harnesses. The power wires carry substantial current and could induce noise into the audio system. 1. Configure the internal XCard crossovers prior to installation. Refer to the “Using the Signal Switching Network” (page 19 for the 250.

    10. Perform a final check of the completed system wiring to ensure that all connections are accurate. Check all power and ground connections for frayed wires and loose connections which could cause problems from road vibrations. 11. After the final inspection is complete, install the power fuse and enjoy listening. During the initial listening period, you may need to “fine tune”...

The XCard shipped with your amplifier is set for Full Range. Each crossover card has two faces: one face operates Full Range, the other has arrows to indicate the edge for selecting HP (high-pass) or LP (low-pass) operation.

    III. MOVE THE DECK. If you're at this step, it's time to turn your system into an “amplified deck” by temporarily relocating the deck right ON TOP of the clean amplifier. Then using very, very short signal cables, connect the output of the deck into the input of the amp and test for noise.

    The IHF-202 standard is a dynamic power measurement and was developed as a means of measuring power in a manner that best represents the Real World operation of an amplifier. Many manufacturers, including Rockford Fosgate, at times will measure amplifier power into a fixed resistor (4 ohm, 2 ohm). While this method is useful in some types of evaluation and testing, it is not representative of an amplifier that is connected to a speaker and playing music.
