[wontonjohnny]

hey guys i need some help....

i have a alpine 4ch amp and its been making static cracking sounds only at low volumes, intermitentely and randomly.

wft is wrong... i redid all my connections and its still messed.

im sure the speakers arnt blown cause they work fine loud and that crackling sound is irrattic not constant....

oh yeah nad dont buy shiet from soundsaround... they didnt give a rats ass, wouldnt even help at all

wire must be loose. Is it in one channel, or all channels?

[wontonjohnny]

all channels

even crackels when the volume is on zero on the deck.

Check to see if any of your speaker wires are touching each other, i.e. +ve and -ve.... it might even be a single strand....

ok, couple of steps you need to try... first, disconnect the rca's going into your amp. Does it still crackle? If yes, your amp or speaker wiring is bad. Being as it is all channels, I would say it is the amp. If no, then reconnect the rca cables at the amp, and disconnect them at the HU. Does it crackle now? If yes, your rca's are bad. If no, then something is wrong with your HU.

Being as it is all channels, I am leaning towards the HU being bad, but try the above tests and let us know.

im not using my rcas.... the signal from the HU out of the rca's is really weak... im using the speaker inputs, not good for interference noise right??? cause i get a buzzing sound that goes louder with the rpm.

you think its the HU?? i hope so cause this amp and speakers are like brand new (since jan) and the HU is like 6 years old.


thanks i will try your test tm and will let you know

my old head unit started doing that after awhile (xtream sound) crap....but it would crackle after awhile be fine...then it go to the point where it crackled constantly.....then one day my rear speakers wouldnt work....and the volume was reallly low even turned all the way up.....then i fixed it by buying another head unit

[wontonjohnny]

ok so i did the tests and its now either the wires from the HU or the HU..... i think im just gonna buy a new deck now and see if that changes anything.

thanks for your help TNer's
