This plug and play harness makes adding a subwoofer to your stock system fast and easy. No need to cut or splice your factory wiring. Simply insert the plug behind the head unit (stereo) run the 17 foot leads to your amplifier or line out converter and you are ready to add some bass to your truck.
Be sure to check out our plug and play amps for your Toyota Tundra CrewMax. They quickly take your stock system from 14 watts to 100 watts RMS to each speaker. In addition, our subwoofer amplifier will power your subs between 600 & 1000 watts RMS.
This kit is offered in two part setup.
Harness 1: This harness is setup to acquire the signal from the Right rear speaker output. They are colored coded to standard 12V industry colors. If your amp accepts high level input, then it will most likely have an auto start feature. You will want to confirm by checking the manual for your amp.
Purple – Right Rear Speaker (+)
Purple with Black Stripe Right – Rear Speaker (-)
Harness 2: This harness is setup to provide a signal wire for amps that do NOT have auto start. This harness will send a signal that will turn your amp on/off when the car is turned on/off.
IMPORTANT NOTE: Your amp / powered sub / etc will require a separate power cable / source. DO NOT USE the 12V wire (YELLOW OR RED) from any harness to power your amp.
