Hi

I bought for my mazda 3 2008, now everytime I plugin the Mpow and turn on Aux, I get this hissing sound. I first though ok, this is probably because I don't have any music playing. I started to play some music and has the music playing and a hissing sound in the background of it.

I don't know why I am getting this. Anyone else run into this issue?

 

It is wired into the car? Does the tone change when you rev the engine? If so, it sounds like it wasn't grounded correctly. I'd either take it back to the shop that installed it, or if you did it yourself, check out the wiring.

 

it is just a device I hook into my aux cable, I did no wiring. It seems consistent, hissing always.

If I just use an aux cable that works just fine.

The device though works in my friends car but he has an after market sound console.
