Sand away any paint from this location; use a star-type-lock washer to secure the connection. Adjust the crossover frequency to limit bass, and provide increased system volume with less distortion. For simplicity, Figures 3 and 4 do not show power, remote and input connections. We recommend listening at low or moderate levels while driving your car. Disconnect the – negative lead from your vehicle’s battery. Check vehicle charging system.
Amplifier may need service; see enclosed warranty card for service information. If not, check the wiring, especially the remote connection from the source unit. This should blink only on musical peaks, and not be on constantly. Amplifier cooling is essential for proper amplifier operation. If your installation differs markedly, you will need to adjust the wire gauge accordingly. Playing loud music in an automobile can hinder your ability to hear traffic and permanently damage your hearing. The fuse value should be selected based on total amplifier-current draw; see chart at right.

Disconnect the – negative lead from your vehicle’s battery. Optional remote level bass control available.
There are two sets of terminals to make it easy to connect multiple referencw. The fuse value should be selected based on total amplifier-current draw; see chart at right.
Dynamic Bass Optimization DBO – This refetence variable filtering with adjustable “Q” below Hz, far beyond conventional “Bass Q” circuits, by allowing the low-frequency output to be optimized for invinity subwoofer applications.
When using the low-level or high-level inputs, the AUX outputs can be used to pass a full-range line-level signal to another amplifier. If your installation differs markedly, you will need to adjust the wire gauge accordingly. When using the low- or high-level inputs, the AUX outputs can be used to pass a full-range line-level signal to another amplifier. Install the control module in the front of the vehicle within easy reach of the driver.
Do not install the fuse ammp this time. This allows you to enhance the bass output of your system at 50Hz up to 12dB. Allows bass to pass through to the speakers; should be selected when powering subwoofers. High-level and low-level input are provided allowing you to interface the Reference a with either an aftermarket or factory installed head units.
The a comes outfitted with a variable 12dB per octave electronic crossover allowing you to optimize system tuning based on speaker location and accompanying loudspeaker components.
Full range preamp outputs are provided facilitating multiple amplifier hookups without the need for costly Y-adapters or signal splitters. Reference subwoofer amplifier with one woofer connection.
This will conserve amplifier power typically wasted on frequencies below the tuned frequency of the enclosure. Allows a high-pass signal through to the speakers; should be used with most loudspeakers can protect your full-range speakers from being overdriven with low frequencies, one cause of speaker damage. Input sensitivity is not set properly, or amplifier or source unit is defective. For vented enclosures, the DBO should be used as a subsonic filter to reduce overexcursion of the woofers.

Mount the amplifier so it is not damaged by the feet of backseat passengers. Speaker connections should be made using a minimum of gauge wire. Mount the amplifier so that it remains dry – never mount an amplifier outside the vehicle or in the engine compartment. Reference subwoofer amplifier with two woofer connections.
Use extreme caution when cutting or drilling in and around these areas. Figures 3 and 4 show how to configure the Reference subwoofer amplifiers models a, a and a.
Choosing a Location and Mounting the Amplifier Choose a mounting location in the trunk or cargo area where the amplifier will not be dam- aged by shifting cargo.

The DBO allows you to adjust the frequency 20Hz – 80Hz as well as the boost level up to 12dB; see Figure 14allowing you to fine-tune the bass in your system to optimize performance.
Amplifier cooling is essential referrence proper amplifier operation. Failure to adequately protect the positive wire from potential damage may result in a vehicle fire.
This should blink only on musical peaks, and not be on constantly. For simplicity, Figures 3 and 4 do not show power, remote and seriies connections. Systems using a separate subwoofer set the crossover mode to HP high-pass for your full-range speakers.
