The Punch 4020 is a 4-channel amplifier which offers 20 Watts per channel when driven into 4 Ohms. The amplifier utilizes a 2/ 4 input selector switch and XCard crossovers.

When building a 4-channel amplifier, a major design challenge is to maintain sound quality in a limited space. For the Punch 4020, Rockford Fosgate Engineers designed the Trans•Ana to- pology which is a fast, short loop circuit allowing the output stage to be driven with a low voltage drive signal. With the addition of a 2/4 input selector switch and XCard crossovers, the 4020 can be configured in many popular system designs without the added cost of external processors. The result is an excellent sounding amplifier in a physically compact area.

The Punch 4020 satisfies the need for a powerful 4-channel amplifier at a competitive price.

We strongly recommend you have your Authorized Rockford Fosgate Dealer install the new Punch 4020 amplifier. If you do choose to install it yourself, please be sure to read the entire manual before beginning.
