Tuning your amp is crucial to proper output and a long healthy life from your amplifier. By following the tuning steps below, your amp will produce maximum CLEAN power, provide the proper frequencies to your speakers / subwoofer(s) and provide many years of great audio!
Step 1: Adjust Amp Knobs & Switch Configuration (Pre-Tune)
Adjust the knobs and switches as listed below:
Step 2: Insert Blue Molex Plugs Into Front, Rear & Subwoofer Inputs:
Step 3: Remote turn on wire
Connect the Blue or Red remote turn on wire included in your PNP wiring system. NOTE: If using an aftermarket head unit, use the blue remote wire from your aftermarket head unit. See our Aftermarket installation instructions here:
Step 3: Subwoofer wire connection
Connect a short piece of 12G wire to your subwoofer output. Strip the ends and be sure the + and – do not come in contact with each other.
Step 4: Output Wire Connections
DO NOT PLUG IN THE BLACK MOLEX PLUGS FROM YOUR PLUG AND PLAY HARNESS AT THIS TIME! We will plug them in AFTER the tuning process has been completed.
Locate the Black Molex connectors that have the SHORT white / gray & purple/ green wires. They are located in the same bag with the Molex / RCA connectors.
NOTE: If you are using aftermarket head unit, you will want to refer our after market head unit / tuning video.
Step 4: Tuning Video Instructions:
NOTE: The TXD10005 is best suited to work with 4 Ohm Front & Rear Speakers. If you have upgraded your speakers, please be certain you are using a component set for your front speakers to ensure you are providing a 4 Ohm load. Resistance below 4 ohms may cause excessive noise.
