Want to crank your tunes while parked without worrying about your car starting? Our new Stereo/Amp isolation harness connects to our second battery kit solenoid. This allows you to have the car off but still play your stereo.
Installation:
For ease of installation, we recommend flipping the solenoid around so the lugs are under the dash.
Plug harness in between the stereo harness coming out of your kicker stereo.
Take the wire with the ring terminal on it and connect it to the positive side of the second battery kit solenoid.
The blue battery cable coming from your factory amp (labeled 12v+) will also need to be relocated to the same lug that you connected the red wire from the isolation harness to.
Made in the USA.

Bolted right on and fit perfectly. Support even confirmed fitment before I ordered.
Finally a shop that actually knows Toyotas. No guesswork, no wrong parts.
Fast shipping and the install guide made it a one-evening job. Stoked.
