Real Time Power Protection (R.T.P.P.) allows for the greatest power output under all load conditions. When output reaches an unsafe level it will be reduced, unlike current limiting which often causes premature protection or failure to protect at all. To get a better understanding of the Punch let’s take a closer look. -

Page 17: Speakers
Speakers Punch 4-Channel amplifiers are rated for safe operation into loads of 2 , or greater in stereo mode or 4 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 2 stereo or 4 bridged/mono. - Page 18 More complex systems such as 12 dB or 18 dB per octave can cause impedance problems if not professionally de- signed. If such a system is required, we recommend consulting an Authorized Rockford Fosgate Dealer.

If the amp plays, check for shorts or blown voice coils in the vehicle's speaker system. If you are still having problems, have the amplifier checked out by an Authorized Rockford Fosgate Dealer. surements, have the head unit checked by an Authorized Dealer or Service Center. - Page 29 If turn- on pop goes away, connect a delay turn-on module (Perfect Interface DT-1) to the amplifier. (See your Authorized Rockford Fosgate Dealer for more infor- mation.) 2. If the noise persists, disconnect the turn-on wire from the head unit and use a different +12 volt power source to turn on the amplifier (i.e., battery direct).
- Page 30 Problem Engine Noise (Whine) Solution 1. Disconnect the speakers from the amplifier. Connect a test speaker to the amplifier output terminals. If the noise goes away, check your speaker leads, speakers and crossovers. 2. If the noise persists, use a "shorting plug" to mute the input signal at the amplifier.

Page 31: Dynamic Power Measurements
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... - Page 32 A 4 ohm speaker may experience a drop in impedance 4- 6 times lower than its nominal (printed) impedance. A speaker will also create phase shifts in the signal that is passed through it. These phase shifts happen because a speaker is an inductor (voice coil) and a capacitor (compliance of the surround/spider), as well as a resistor (voice coil wire).
- Page 33 What is an Amplifier? An amplifier by definition is a voltage generating device, recreating the signal which is input to in an identical but amplified form. It will be connected to a reactive load (the speaker). The impedance of this load and phase of the signal passing through the load will vary, dependent upon the frequency and amplitude of the input signal (music).
