I need help with my subwoofer and my car Honda Accord 2008 Coupe Lx-s?

• I need help with my subwoofer and my car Honda Accord 2008 Coupe Lx-s? i was facing the same problem as somebody else so i just copied and pasted it here. I have a 2008 Honda Accord Coupe your subs will hum everytime you turn the car on, its only a for half a 2nd but can get really annoying, also if you have the premium audio system, you cant connect the in line converter to the rear subs since honda made it to where everything you accelerate the car, it sends out a signal through the speakers, your subs will go off even with the factory dash Off. What should i do??

• Answer:

  Your problem is Honda's ANC (Active Noise Cancellation) system. It uses a pair of microphones in the vehicle to pick up ambient noise, and plays an out-of-phase noise through the speakers to reduce the overall noise level in the cabin. This is similar to the way noise-canceling headphones work. The trouble is that your line-out converter will pick up the noise and send it to your amplifier, which turns it into a rumble through your subwoofers. The solution is to disconnect the two microphones. One is located in the overhead console above your windshield; the other is located under the rear deck panel. The front microphone is also used for voice-activation and Bluetooth features, so if you disconnect it entirely you'll lose these features as well (and you'll lose the quieting effect of the ANC system). You might want to search Honda-owners forums for more information.
