Hissing Noise On Speakers After Hu Install....


Recommended Posts

so yea whenever i turn on my car and the headunit kicks on the speakers have a nasty hissing noise. as i turn the volume up the hissing noise is drowned out by music. but also when i turn it up i can hear a slight pop as i hit the + button.

so is this just a result of the 20 wrms on my stock speakers? or is it sumthin more serious?

I had this through my subs and it turned out to be a ground on the HU... I would check that first.

sounds like a bad ground somewhere . try grounding a rca .if it helps run a ground and solder it to the rca.

if you unplug your rca's when your deck is on will blow your rca's out also and you will get engine noise.
