is my receiver crazy or my car?
 

hey bros, i just got a pionneer receiver and i hook it up to my car. Everything seem to be very perfect until i start driving.

When i start driving my volume is loud. when i stop at an intersection the volume descrease. i have no idea what happen.

Its weird because when i drive then the music is loud when i stop it descrease but you can still hear it but just low.

I was wondering does that have anything to do with my ground wire?

any help bros?

Does that deck have the noise cancellation feature? On some stereo's they will increase in volume as you increase in speed to compensate for road/wind noise. I haven't really seen that in an aftermarket deck though....

Are your alternator and battery ok? Have you had them tested? How much wattage are you pushing?
