I am looking for a Boss BV9970 wiring harness.

if you are sure the speakers are good and the wiring to the speaker is correct then you need to look at the Boss.. a volt meter on the output either at the speakers or the harness should tell you, as it fluctuates with the volume of the unit, hopefully you do have power to the Boss...

Yes, it happened to me plenty, heard of the keyboard cleaner dust off? Try that it's worked for me

sounds like a loose connection on the aux input. boss has a pretty bad reputation for there usb / aux connections inside the unit. also if your right rear and right dont play on anything its bc you have them turned down. or if this is recently installed they got mixed up. please let me know more details so i can better help you

There could be a few things wrong with it. The first thing I would do is check the ground wire. It should be solidly connected to a paint-free surface of your vehicle that is connected to the chassis. The next thing I would check is the connection between the power wire lead from the vehicle and the lead from the head unit. If neither of those are the problem, the only other thing it could be (other than a faulty wire somewhere along the power circuit, which can be tested for using an ammeter) is a lack of power to the power wire lead from the car. Test that wire using an ammeter and make sure it is receiving power.

it should be a blue/white wire.

The only way the BV9970 will work with an ipod is by using a male male phono lead, from the headphone socket in the ipod to the AUX in on the front of the stereo.

you can't watch a video on the system unless the parking brake is on. you have to buypass the parking brake system in order to have a video on while driving

what is a boss bv9970???

Sounds like the color module is out. Your gonna have to send it to an electronic repair place if it isn't under warranty.
