Understanding your amplifier’s features what is an amplifier?... An amplifier, by definition, is a device that receives a small audio signal on its input and reproduces it with larger voltages (or current) on its output. Ideally there should be no internal modifications of the signal other than volt...

Noise reduction and downward expansion high quality compact discs provide very wide range volume levels with low background hiss levels. Unfortunately, the car is a very noisy electrical environment so vehicle noises (pops and alternator whine) often creep into the audio signal somewhere in the inst...

Amplifier controls and operation 1. Tone controls the tonal quality of the signal passed through the amplifier can be in the bass and treble regions using the internal tone controls. Although somewhat redunda to those on the radio, these controls help correct for small equalization problems in the c...

Amplifier connections and interface 1. Ground line this is the high current ground connection to the chassis of the car. It should be fastened to a clean ground connection in the car, capable of handling high current loads. Do not run a wire up to the car battery ground for this line. It should rema...

Speaker configurations many audio systems can be generated from the three basic speaker output configurations of this amplifier. They are: 4 channel mode (full range audio); 3 channel mode (2 channel pass/l channel low-pass); and 2 channel mode (2 channel full-range or low-pass subwoofer). Possible ...

Final installation proper installation of your amplifier should also address several areas; adequate mounting and ventilation, proper signal input interface, correct use of internal crossover networks, “clean” power/ground wiring, proper fusing, and power/speaker wiring. Adequate mounting and ventil...
