klevi · 25th April 2011, 03:26 PM

HI TO ALL.
I HAVE THIS CAR AMPLIFIER THAT A FRIEND GIVE TO ME.
I DONT KNOW THE BRAND OR ANOTHER DETAIL.
I SEARCH ON THE INTERNET BUT NOTHINK.
ITS 6 CH -HI,MID,LOW.
MY BROTHER WAS TRYING (I DONT KNOW WHAT) AND HE
CONNECT THE HI OUTPUT OF THE CAR STEREO DIRECTLY TO
THE PREAMP (I THINK)
AND NOW THE NORMAL INPUT IS NOT OK.
I MEAN I CONNECT THE THE AMP FROM THE OUTPUT STEREO AMP
BUT NO AUDIO IS COMMING FROM THE AMP.
I THINK THAT I BURNOUT THE ""KIA 4559 S "" BECAUSE THEY ARE
THE FIRST INPUT IC BEFORE TRANSISTORS AND I HAVE TRY
THE TRANSISTORS AND ARE OK I THINK.
IF ANY ONE KNOW HOW TO TEST THE KIA4559S PLEASE ADVICE ME.
PLEASE IF SOME BODY HAVE ANY IDEA HELP ME.

Why are you shouting at us (capitals)? E

Firstly, stop yelling.

Secondly, if you had used google you would see the KIA4558 is a dual opamp. If you have connected speaker outputs to them, they're fried. Dual opamps are easy to get, but those in the SIP package are not.

There IS a car audio forum at DiyAudio, maybe some advice there.
