For those hwo dont know me i have a kicker amp powering my internal speakers Alpine type s (Comp in front COax in back) and a JBl 600.1 powering my 2 12 in shivas.

Long story short i got alternator whine i checked every possible wire and im still getting it. I changed grounds and what not . However now my sound is fading in and out on the interior speakers. The subs still bump but no sound or whine from interior speakers. THen after a while it will come back or if i tinker with the RCA cable going into the kicker amp it will come back.

I also tried a alternator filter and that did not help. ANy suggestions ?

 

Have you tried replacing the RCA cable?

Tony

 

yes i did still didnt work

 

Have you tried a ground loop isolator ?

 

If the sound is intermittent when you tinker with the RCA inputs on the Kicker amp and you're sure it's not the cable...

EDIT: Another hint... And if the sound is intermittent on all your speakers that are running off the Kicker amp and you're sure it's not the cable...

(the answer should be quite obvious)

Don't do that. I tried the PAC isolator and the radio shack. They actually induce noise themselves if not positioned correctly. Also, it cuts out mid-bass. That is not speculation either. I tried them.

 

i told him it was the kicker amp, but he just got it and it worked fine at 1st, so i was confused.

 

yeah i tried 3 rca cables its not the cable and the amp was bought brand new

 

If you mean the alternator itself is whining, your alternator is dying. Probably won't last long. But if you're just getting a whine through your speakers, never mind. Just thought I'd post in case.

 

its his interior speakers which does lead me to believe somehow the inputs on the amp got messed up.

 

That's the conclusion I was trying to get him to find on his own.

is there any way to test the input on the amp i cant hook up the speakers to the jbl amp cuz that would blow them !

 

bizzump audio heads !!!

 

GUys i have turned off the stereo lol the alternator whine is too much for me. THe subs will only leave again if i can get this stuff fixed. Pearl im counting on you lol

 

heh, I've done the same... your head unit ground might be bad like I suspect mine is

 

Did you not post a long time ago that if you played around with the RCAs going into the amp the noise would come back? And if you tried a few different RCA cords and ruled them out then what else could it be? If everything you've told us is true, it has to be the RCA inputs on the amp. How can we convince you of this?

Is there anyway to check this wihout getting another amp sent over?
