Hey guys, I just installed a new deck in my 2002 accord. I just want to know were a suitable ground would be. I installed it using one of those wiring harness but when I connect the deck ground wire to the harness ground wire it makes a whistleing sound when I accelerate. So I belief I need to find a better ground. So does anyone know where I can ground it??

 

you can reground it to the lower dash metal frame scrape the metal for clean contact
if that doesnt fix it its ur head unit
do u have a amp?

 

What is the make and model of the HU? 94
