- Page 6 POWER - GROUND - REMOTE All Crossfi re amplifi ers are optimized to work within 12.00 to 14.5 volts DC. Therefore, as a precaution, the vehicle’s electrical system should be checked for correct voltage supply with the help of a voltmeter. First, connect the test leads of the voltmeter to the battery terminals with the ignition of the vehicle in the off position.
- Page 7 SPEAKER OUTPUT LOAD Please be aware of the minimum impedance you may apply to your particular model amplifier. See chart below for more informa- tion. Any lower impedance than the minimum can send the amplifier into current protection or possibly damage the circuitry. To prevent damage, use the following formulas to help you figure out the load you are placing on your amplifier.

- Page 9 CLASS D WIRING CONFIGURATIONS The Class D amplifiers are single channel amplifiers. Unlike Crossfire Class A/B amplifiers, these operate as single channel, therefore one amplifier cannot be bridged by itself. Do not confuse the pair of speaker outputs as left and right. The two outputs provided are strictly for convenience and are paralleled internally on the circuit board of the amplifier.
- Page 10 SINGLE INPUTS Getting a clear signal from the head unit to the amplifier is very important. To achieve this, the proper signal cables (RCA style) must be used. Estimate the length of the cables necessary. Take note that signal cable manufacturers will probably not have the exact length necessary for your vehicle.
- Page 11 Master 0: this setting will maintain the same phase as the signal applied to it. 1. Use this setting if the amplifier is not bridged with another amplifier. 2. When bridging the amplifiers, use this setting only on the amplifier that is connected to the head unit. Master 180: this setting will reverse the phase 180 degrees of the signal input into the amplifier.
- Page 12 LOW LEVEL INPUT CONFIGURATIONS CLASS A/B Please note that your amplifier may differ from those shown on this page. The following page has ad- ditional model amplifiers and connection diagrams and configurations. 2 CH. CONFIGURATION 4 CH. WITH (2) RCA INPUTS CONFIGURATION 4 CH.
- Page 13 LOW LEVEL INPUT CONFIGURATIONS CLASS D Please note that your amplifier may differ from those shown on this page. SINGLE AMPLIFIER CONFIGURATION DUAL AMPLIFIER CONFIGURATION (Using 2 Amplifiers) This example shows how to use 1 single pre-amp output to run dual amplifiers by using the RCA output provided by the Crossfire Class D amplifiers.
- Page 14 IMPORTANT!! The majority of failures seen with Class D amplifiers are due to people using them in vehicles without the proper electrical con- siderations. The common misconception about Class D amplifiers contributes to this problem, since the VRA1000D is Class D amplifier and very efficient, the misconception is that it doesn’t pull amounts of current.
