Tacotunes.com TXD 3204 EZAMP – how to properly setup and tune your amplifier.

Now that you have completed the initial installation process, you will want to tune the amp for your vehicle. Each vehicle can vary just a bit and this guide will walk you through tuning your amp.

At this point you have completed the following:

1. All power (positive / ground) connections have been tripled check to ensure they are all tight.

2. The Plug and play wire harness has been connected to your head unit and the leads have been routed to your amp mounting location.

3. The Plug and Play wires are connected to the RCA line adapters.

4. The RCA line adapters are plugged into the amplifier RCA connections.

5. The INPUT wires (RCAs) should be plugged into the amplifier. Double check you are connecting to the INPUT side.

6. Turn key on and ensure the amplifier lights up blue. Turn the ignition off.

7. The Front and Rear OUTPUT wires (go to speakers) should NOT be connected to the speakers at this time.

8. On the amp itself, set the HPF (High Pass Filter), Front SENS (Input Gain / Sensitivity), Subsonic, Boost, LPF and Rear SENS (Input Gain / Sensitivity). Set the LPF / FULL switch to FULL.

9. Ensure your head unit is set to flat signal. You need to check this for all audio sources. Ensure the TREBLE, MID and BASS are all set in the middle Ensure the Front / Rear Fader is set to middle.

10. Insert the CD with the test tones you can download from HERE. AT this time, we do not recommend using a phone to set up the amplifiers.

11. Play the 1khz test tone.

12. Set the volume on your head unit to 50. NOTE: This is assuming 60 is your max volume.

13. AT this point you should hear nothing coming from your speakers. NOTE: You might hear a high pitched sound coming from the amp.

14. Connect your digital multimeter to the front left output of your amplifier. Turn the FRONT SENS knob until your amp reaches 17.5V. Your multi-meters should be set to AC voltage.

15. Change test tone to 80Hz test tone.

16. Enter the AC voltage in the field below. This will calculate the voltage necessary to tune your amplifier. Next turn the HPF clockwise (should have been down at 25Hz to start) until the AC Voltage on your voltmeter matches the field below.

17. Connect your multi-meter to the left rear output and turn the REAR SENS up until you reach 15.5 Volts.

18. Congratulations you have completed tuning your 4 channel amplifier.

NOTE: If you are using our mono (subwoofer) amp. Be sure you do not mix up the connections. The wires appears to be the same, but they are not.

Tools you will need:

• Digital Multimeter / Voltmeter
• Small Screwdriver that will fit in amp knobs.
• Test Tones – same tones used to set the gain on your amp.

Steps you should have already completed:

• Set the head unit to maximum unclipped volume. (Speaker Wires Should NOT be hooked up!)
• All internal EQs, adjustments on the head unit should be set flat. Not boosted or lowered.
• Set the gain(s) on your amp before you setup the crossovers.
• Decide on your crossover point and acquire the test tones you will need. The most common crossover point is 80Hz. – Click here for link to test tones and requirements.
• Turn both High Pass Filter (HPF) knobs all the way to 15Hz (as far left as possible)
• Turn Low Pass Filter (LPF) knob all the way to 300Hz (as far right as possible)

Setting High Pass Filters (Speakers):

• Remove all speaker wiring from the amplifier. (label your speaker wiring)
• Set the multi-meter to ACV (Alternating Current Voltage)
• Insert the multi-meter leads into channel 1 and screw down gently (See picture below for channel layout and explanation)
• Enter the voltage displaying on your multi-meter into field “Voltage 1”

• Turn the Front HPF knob to the right until it matches as closely as possible to “Crossover Voltage”.
• Repeat the same steps for channel 3 – turn the Rear HPF knob to the right until it matches as closely as possible to “Crossover Voltage”.

Setting Low Pass Filter (Subwoofer)

• Connect the multi meter leads to the subwoofer amp output.

• Turn on vehicle and play test tone at roughly half of the maximum volume (does not need to be exact)
• Enter the voltage displaying on your multi-meter into field “Voltage 1”
• Turn the LPF knob to the left until it matches as closely as possible to “Crossover Voltage”.

The crossovers are now set at desired crossover setting. NOTE: It is NOT uncommon for amps to be marked incorrectly there are many factors and most manufactures provide the numbers as a guide.

Tuning your amp(s) 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!

Before starting the tuning process, you must complete the following steps:

• Power Wire (Proper size / Gauge) is connected from battery to TXD10005. ALL Fuses/Connections are installed and tightened per installation instructions.
• Ground Wire(s) (Proper Size / Gauge) is connected and tightened correctly.
• Plug and Play wiring harness is installed per installation instructions – for your model Toyota.
• Ensure that your OUTPUT plugs are NOT connected as shown in the installation diagram.

At this point your TXD10005 is powering on and you are ready to proceed to the tuning process.

Step 1: Obtain the tuning (test) tones for your TXD10005

If your Toyota is equipped with a CD PLAYER –

IMPORTANT: NEVER PLAY TEST / TUNING TONES ON AMPLIFIED SPEAKERS / SUBS, YOU WILL DAMAGE THEM.

Step 2: Set all the knobs as shown in Pre-Tune Illustration 1

(Pre-Tune Illustration 1)

Adjust Amp Knobs & Switch Configuration

Adjust the knobs and switches as listed below:

Step 3: Insert Blue Molex Plugs Into Front, Rear & Subwoofer Inputs:

NOTE: If using NTUNE6 or Aftermarket Radio Click Here

Step 4: 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 5: 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 6: 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 7: 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.

ReCurve EZQ User Manual installation and setup guide (JBL)

Welcome to the ReCurve EZQ User Manual installation and setup guide for Toyota’s with the upgraded JBL audio system. If you are reviewed our installation guide(s)/vide0(s) for the NON JBL Toyota’s , you will see we have a plug and play system

Below we have a list of videos and the user manual to help you setup the ReCurve EZQ. We highly recommend that you watch the videos and read the entire manual before you begin the installation process. You might even want to setup a “dry run” on your living room floor to see how the entire audio system will tie together. Plan ahead and the installation will go much smoother. We are updating the videos and manual regularly keep checking back.

Professional Installers:

DO NOT CUT OR SPLICE FACTORY WIRES!!! READ THE INSTRUCTIONS!

We understand you know what are you doing. However, the ReCurve EZQ does not work in the manner you are accustomed to . . it is not a one size fit all device . . . all of your questions will be answered if you take the time to review the instructions. Most of our support issues come from professional installers that rush through the installation process.

Toyota owners, be sure to convey to your installer to review the installation instructions.

ReCurve EZQ Toyota Tundra 2014+

In the 2014+ Toyota Tundra(s), Toyota moved the power source for the front and rear speakers to an external power source located under the passenger seat.

Simply unplug the two harnesses that plug into that small power source. The ReCurve and wiring harness will make the proper adjustments. If you do not unplug the power source, the head unit will not send the signal to the ReCurve.

After removing the two plugs from the power source continue the installation as demonstrated in video.
