The Punch amplifiers are capable of bridged mono configurations. This configuration enables you to:
•Run a single woofer in a stereo system
•Run two bridged amplifiers as a high power stereo system
•Run one amplifier with a bridged mono woofer and another as a
For more information refer to the wiring diagrams begin- ning on page 17.
Caution! Punch amplifiers are not recommended for impedance loads below 2Ω stereo or 4Ω bridged.
Be sure to observe proper speaker terminal polarity throughout the system. It is critical for the Punch to use the correct negative terminals for right and left channels, since the RIGHT NEGATIVE
When wiring speakers to the amplifiers, we recommend using fuses for speaker protection. (See your Authorized Rockford Fosgate Dealer for more information.)
A passive crossover is a circuit that employs capacitors and/or coils and is placed on speaker leads between the amplifier and speaker to delegate frequencies in the speaker’s optimum performance range.
The most commonly used filter networks are 6 dB per octave systems. These are easy to construct and require a minimum number of parts. A filter network can perform one of three functions. These are highpass (capacitors), lowpass (inductors, chokes or coils) and bandpass (com- bination of a capacitor and a coil).
This result, limiting the types of frequency to the speaker, is directly dependent upon the speaker’s impedance and component values.
