2007 -2017 Toyota Highlander Plug and Play Replacement Amplifiers – NON JBL
You want to add an amp and keep your stock stereo head unit (stereo)? Not a problem!
YES! Works with aftermarket head units (stereo)s also!
NOTE: This will NOT work with JBL equipped Tacomas
These plug and and play amps are a direct inline / plug and play setup for your Toyota Highlander. Per our instructions (coming very soon – see Tacoma vids below for idea), you simply run the plug and play harness, run a power wire to your battery and now you will boost your stock head unit OR aftermarket head unit to 70 watts to front speakers and 50 watts to rear. . In addition, you can select the optional mono / subwoofer amplifier and provide up to 600 or 1000 watts RMS to your after market subwoofer.
Please select the options you wish to add on to your plug and play amp kit. The TXD3204 4 channel amplifier is required. You can select to purchase the TXD6001 or TXD10001 subwoofer amp at a later date.
Please note your stock speakers are not setup to handle this much power. So be sure to check out our plug and play speaker upgrade options. In addition, we even offer turnkey packages to install a complete audio system in your Toyota Highlander. If you are planning to use your own speakers, be sure to check out our plug and play wire harness adapters. Our harness adapters plug directly in the stock wiring. Be sure to check out our videos on how to install component speakers in your Highlander.
NOTE: For the best results be sure your speakers are presenting a 4 Ohm load to your amp. Most speakers present a 4 ohm load.
Installation is much quicker and easier than a standard amplifier installation.

Power Wire Information:
Oxygen Free Copper (OFC) provides the best conductivity between your battery and amplifier(s). Cooper Clad Aluminum (CCA) is a great alternative to OFC when used properly. OFC & CCA specs can vary greatly. The products we use have been bench and field tested to ensure you are getting the maximum power delivered to your amplifiers.
The OFC and CCA products we use in house have a 65% ratio. To help explain this when we use 4G OFC, we can we can provide up to 125 amps (125 x 12 = 1,500 watts) of power to your amps with minimal loss in power.The CCA we use has roughly 65% efficiency of OFC. This means the 4G CCA can provide approximately 82 (82 x 12 = 984 watts) amps of power to your amplifiers.
Please note we are using 95% efficiency of our Class D amps in the calculation above.. These numbers will change if are using older style class AB & D amps.
There are a number of factors that are not addressed in our calculation above. If you are going to use your own install kit, be sure to do your homework. The calculation above is taking into account a maximum of 15 feet from the battery to the distribution block. IN addition, the power cables from the distribution block are less than 1 foot while the ground cables are less than 2 feet.
