PRODUCT TERMS:
This harness will provide 4 output channels (FL, RF, RL, RR) from my stock head unit. I understand that I will need to supply an LOC/DSP/Sound Processor that will properly output the desired 4, 5, or 6 channel low-level output that is required to provide the signal for my amplifiers.
I understand that not all LOC/DSP/Sound Processors may not work properly with my stock head unit (Radio).
I understand this product is NON REFUNDABLE if the product packaging is “opened”. NO EXCEPTIONS.
I understand that support for this product is limited to ensuring signal delivery to your LOC/DSP/Sound Processor. We are unable to provide support for LOC/DSP/Sound Processors/Amplifiers purchased from other vendors.
NOTE: We suggest using NTUNE6 or a similar product designed to work with your Toyota Stock Stereo. Keep in mind lower end LOC units often cause “Newer Model” head unit errors and/or head unit “shutdown” issues.
