Aight fellas, i have road noise like CRAAAAAZY, i had no road noise at all when i had JUST my 250/1 hooked up, my RCA's are on opposite sides of my power, so i dont know what else i could do, but i just hooked up a little memphis amp for my mb quarts and as soon as i start the car i got the noise, any tips?

 

IT's not road noise, it's alternator noise, and it has nothing to do with your RCA's, it has to do with your amplifier grounds and your headunit ground. Make sure both are good. If you think they are good, move them to another location where they are better Some spots are decievingly poor. The shorter the wire the better as well.

 

preciate it, where would be a better place? i think i'm gonna go into my spare tire well, that's where my other amp ground is
