Note: When numerous amplifiers are used in the same system, look into using a relay with a separate power wire connected to an alternative power source to take the strain off the source unit. Normal source units can only keep a constant 12 volts to 2 or possibly 3 amps. This wire should also be run on the away from the RCA cables.

•CAP+: This 8 gauge terminal is internally wired in parallel with the +12V on the StreetWires Power connector. It is the ideal connection point for the positive side of a capacitor to increase the amplifier’s performance.

•CAP-: This 8 gauge terminal is internally wired in parallel with the GND on the StreetWires Power

connector. It is the ideal connection point for the negative side of the capacitor to increase the amplifier’s performance.

Double check all the previous connection installation steps, in particular the speaker and power wiring. Securely mount the amplifier. If everything is in order, reconnect the vehicle’s negative battery connection and begin following the feature setup and adjustment steps.

Feature Setup and Adjustments

1.Selecting the Input Sensitivity Range – Before you turn on your system, you must select the proper input sensitivity range on your amp using the button labeled INPUT SENS located in the GAIN CONTROL section of the control panel.

•Setting for Aftermarket Source Units: Refer to your aftermarket owner’s manual for line level output specification. If the specification is not available, please follow the instructions listed below.

X1 POSITION: 100mV–1V (Typically for RCA Input)

•Setting for Factory (OEM) Source Units: To check the amount of voltage that is present from the source unit, take a multi meter, or a volt/ohm meter, on the A/C setting, (range from 100mV up to 10 volts) attach the positive and negative leads directly to any exposed speaker. It will not matter if the polarity is correct, it will read the same amount of voltage.

X10 POSITION: 1V–10V (Typically for Speaker Level Input)

Note: It is important not to have the amp set up to receive a low voltage signal and give it a high voltage signal. Doing this can cause damage to the amp.

2.Adjusting The Gain Control(s) – Before you start setting your amp gains, be sure to defeat all EQs (“off” position). You want to set the gain levels properly BEFORE applying any equalization.

Start with the source unit’s volume around ¾ of the way up, and the gain on the amp all the way down (counter-clockwise). Slowly increase the gain clockwise until the speaker starts to distort. Immediately decrease gain until the distortion goes away. This will be a good reference point on the volume control to where the signal starts to distort. Remember every CD will be different; use common sense and constantly listen for obvious distortion and adjust volume accordingly. The gain on the amp has nothing to do with how much power the amp can produce, just how fast the amp puts out max power. Just like in an automobile, full throttle is very rarely needed.

3.Adjusting the Hi, 12dB / Low, 24dB Mono @ 40Hz – 350Hz Variable X-over Frequency Controls –

•Setting for Subwoofers: First enable the electronic crossover by selecting the “ON” position of the X- OVER switch, and then select the “L-PASS” (Low pass) position on the L-PASS/H-Pass switch. Next, using “L-PASS CROSSOVER” you now have control over what frequency you want your amp to start crossing over your signal. By turning this control all the way counter-clockwise, you are crossing the signal over at 40Hz (the range is counter-clockwise 40Hz to clockwise 350Hz). This means that the amp will send the woofers frequencies from 20Hz to 40Hz and then start to taper down as the frequencies go over 40Hz (24dB/octave roll off). The industry standard for low pass crossover point is right around 90Hz. However by experimenting with the cross over point (higher or lower) you will find what sounds best in this install. This amp uses a 24-decibel per octave roll off, which is pretty steep, or tapers off fairly quickly from the crossover point. This design complements both the subwoofer and the mid to provide greater musical detail.

•Setting for Components and Separates: First enable the electronic crossover by selecting the “ON” position of the X-OVER switch, and then select the “H-PASS” (High pass) position on the L-PASS/H-Pass switch. Next, using “H-PASS CROSSOVER” you now have control over what frequency you want your amp to start crossing over your signal. By turning this control all the way counter-clockwise you are crossing the signal over at 40Hz (the range is counter-clockwise 40Hz to clockwise 350Hz). This means that the amp
