  1. Jose, in order for you to bypass the factory amp, you would have to run new wires to all your speakers and replace all your speakers. The factory speakers run on a different ohm rating or impedance that is not compatible with your aftermarket radio. Aftermarket radios run on a 4 ohm rating but your factory speakers do not. Hope this helps. Good luck with your 2005 Nissan Quest amplifier bypass.

  2. I have no sound from my speakers. Everything on the head unit works fine but no sound. I’ve check for blown fuese their okay i’ve check my speakers their okay also could it be the factory amp. If so how can i bypass it or can i just cut the wire that powers the amplifier

  3. Paul, we suggest you purchase an automotive auxiliary input adapter. This adapter will allow you to input any Apple iPod, mp3 player or portable music player into your factory radio. This is the easiest and most cost effective way to add an audio input into your factory stereo directly rather than over the air. Here is the adapter you will need:
