Many new and factory radios require a reset code when disconnected from battery power. This is an anti-theft feature. Before unplugging power, you must determine if your radio/source unit requires a reset code. Check the operation manual for your vehicle or contact the dealer.

It is critical to use the proper power and ground cable for your amplifier. Always use high quality copper cable. Be sure to use the proper fuse size for each model. The requirements are as follows:

Note: Some models require an external fuse (ext).

Follow this 12-step installation guide:

1. Disconnect negative battery terminal: Place the terminal in a secure position so it won’t accidentally contact the negative battery post.

2. Run Cables: Properly route power, speaker, and RCA cables through the vehicle.

3. Mount Amplifier: Choose a location with adequate air ventilation. Mount the amplifier to a secure surface, but not upside down.

4. Chassis Ground: Choose a location close to the amplifier. Scrape away paint to expose bare metal and use a nut and bolt. Do not use an existing factory bolt.

5. Negative Power Connection: Attach the chassis ground cable to the amplifier negative (GND) terminal. Ensure this connection is very tight.

6. Remote Turn-on Connection: Attach the remote turn-on wire to the amplifier remote (REM) terminal from the remote output of the source unit.

7. Positive Power Connection: Attach the main power cable to the amplifier +12V terminal. The cable must run directly to the battery, be properly fused, and be very tight.

8. Signal Input Connection: Connect the RCA cables to the INPUT connectors.

9. Level Control: Before powering on, turn the LEVEL control completely counter-clockwise to its minimum setting.

10. Speaker Connections: Connect the speaker cables to the speaker output connectors according to your desired configuration (Stereo, Bridged, or Monoblock).

11. Positive Battery Connection: Connect the power cable to the positive battery terminal. The power cable must be fused within 18 inches of the battery terminal.

12. Re-connect Negative Battery Terminal: Re-connect the negative battery terminal, making sure it is securely tightened. Be prepared to disarm your vehicle’s alarm and enter your radio/source unit code.

Connect the speaker cables to the speaker output connectors. Follow the configuration that best fits your system.

Stereo:

Connect the left speaker positive wire to the LEFT+ terminal and the negative wire to the LEFT- terminal. Connect the right speaker positive wire to the RIGHT+ terminal and the negative wire to the RIGHT- terminal.

Bridged:

To bridge the amplifier for a single speaker (like a subwoofer), connect the speaker’s positive wire to the LEFT+ terminal and the speaker’s negative wire to the RIGHT- terminal.

Monoblock single woofer:

Connect the woofer’s positive wire to one of the + terminals and the negative wire to one of the – terminals. The output terminals are internally connected in parallel.

Monoblock multiple woofers:

Connect the positive wire from the first woofer to a + terminal and the negative wire to a – terminal. Connect the second woofer’s wires to the remaining + and – terminals. Ensure the final impedance load is safe for the amplifier.

This is a critical step to properly adjust your amplifier to match the signal output level of your source unit. This is not a volume control. The input level is adjustable from 9V to 0.2V.

1. If possible, with the source unit off, confirm that the primary volume control is turned down (counter clockwise).

2. Turn on the source unit (CD, or MP3 player). Re-confirm that the volume is turned down. Make sure the source unit controls; balance, fader, bass and treble are all set to center or “0” adjustment. Make sure that the green LED on the end of the amplifier is illuminated.

3. Play a clean musical selection of which you are very familiar. A CD is preferred. Do not use radio signals for level setting. Hit play and start turning the volume of the source unit up.

4. Stop increasing the source unit volume when you reach 3/4 (about 75%) or until you hear speakers begin to slightly start producing distortion.

5. Increase the amplifier level (clockwise) until distortion is heard, then back the level down (counter clockwise) until the distortion is eliminated. Small adjustments may need to be made to balance the levels of multiple amplifiers.

Input Mode: The MODE switch will “sum” or combine the right and left channel signals in the MONO position to improve bass performance. Select MONO only when the amp is being used for subwoofers. Otherwise, select STEREO.

Xover Mode: This switch sets the type of crossover that will be active. Options are FULL (all frequencies pass), HP (High Pass Filter), and LP (Low Pass Filter).

High pass Adjustment (HPF): This control will limit the output below the selected frequency (variable from 60Hz to 1.3KHz). It is used to protect midrange and high-frequency speakers.

Low pass Adjustment (LPF): This control will limit the output above the selected frequency (variable from 35Hz to 250Hz). It is used to create a smooth transition to higher frequency speakers, typically for subwoofers.

Bass Boost (BASS EQ): This control increases the power output at 45Hz for more pronounced bass (variable from 0 to 10dB). Exercise caution when using this control. Increase the level in small amounts until distortion is noticed, then back off a little.

Remote Level Control: Some models include a bass remote. Avoid adjusting the bass remote while operating the vehicle.
