Page 3: Introduction
The AF/2HD has a built-in 1/2 amp fuse for protection from excessive current drives. C O N C E A L E D M O U N T I N G The AF/2HD’s concise cabinet gives the installer the option of concealing the unit anywhere in the automobile without worrying about heat dissipation. -
Page 4: Input And Output Levels
Speaker-level inputs must be attenuated to under 1.O VRMS. Net gain in the filter passband of the AF/2HD is unity. (Output levels are equal to input levels) POWER WIRING INSTRUCTIONS The Black 16-gauge wire should be grounded to the chassis. The White 16-gauge wire should be connected to a source of constant +12-Volt power. -
Page 5: Frequency Selection
See Fig. 1 for module locations. WARNING! TURN OFF SYSTEM BEFORE REMOVING MODULES! BAND SELECTION Both channels in the AF/2HD can be defined as either high or low pass fiters allowing the following combinations: CHANNEL B: LOWPASS CHANNEL A: HIGHPASS... - Page 6 The selection is done simply by placing the capacitor module (C) in the socket location marked High or Low on the PC board (See Figure 2). The empty location is where the resistor frequency module (R) is placed. See the pictures in band and frequency section. Note: Each channel can do both types of filters depending on where you put the capacitor module.

Page 9: Choosing Crossover Frequencies
The use of 1/3 octave RTA can help you determine if a problem exists and at what frequency. The following crossover frequencies work the best with Rockford Fosgate drivers, and provide a good foundation for any autosound system. -
