background static

[trublew]

i hooked up a system in my truck, and have some experience with audio equipment, but for some reason i have some background static when i crank it up if the song hasnt started playing or it just cant drown it out. im using a pioneer head unit, infinity kappa component fronts, alpine 3 way rears, a alpine amp, no sub. any suggestions where to start?

is the truck running when this happens.. and is it a cd you are trying to play

Check your grounds. Engine whine is pretty common in these rides is seems. Do a search too. there are a few threads with some more info.

i tried searching but all i found was engine whine and thats not what mine is... my problem is just that when the radio is cranked up over halfway or so it sounds like an old record with the background static noise... not like the engine whine that people have problems with...

it is an electrical hum from teh internal amp in thehead unit.. almost every stereo i have ever had has done this including in home ones.. if there is no signal and you crank it up it creates white noise.. the only time i did not hear this from a head unit it was a high end unit or a bose system made for clarity.

so there's no way to get rid of it?

how high end are we talkiing? like what head unit can i buy to make this go away...its very annoying when listening to my music cranked and i get static in between songs...

do some research on head units and look for cd signal to noise in the specs of the head unit.. the higher the number in db the less noice will be present
