Impedance

Punch 4-Channel amplifiers are rated for safe operation into loads of 2Ω , or greater in stereo mode or 4Ω in bridged/mono configurations. The primary loads on any amplifier come from directly connected speakers without using capacitors. The measured resistance for each side should not be less than 2Ω stereo or 4Ω bridged/mono.

The Punch 4-Channel amplifiers are capable of bridged/ mono configurations.

This configuration enables you to:

•Run amplifier as a separate 2 channel subwoofer or satellite amplifier.

•Create a high power stereo system

•Run 2 channels with a bridged mono woofer and the other 2 as a high-frequency stereo amp, etc.

Note: Both Punch 4-Channel amplifiers allow the above 3 configurations all in one.

For more information refer to the wiring diagrams begin- ning on page 18.

Note: To bridge the amplifier use the L+ and R– speaker connectors.

Caution! Punch 4-Channel amplifiers are not recom- mended for impedance loads below 2Ω stereo or 4Ω bridged/mono.

Be sure to observe proper speaker terminal polarity throughout the system. It is critical for the Punch 4- Channel to use the correct negative terminals for right and left channels, since the RIGHT NEGATIVE

(–)terminal is the “hot” terminal for the right speaker. DO NOT chassis ground any of the speaker leads as unstable operation may result.

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.
