[funkydog]

hi ppl.. juz did my ICE 1 week ago ......

so far so good ..... only this small bugging problem......

theres this "zzzz" electric sound coming from the tweeters.... all 4 tweeters.......

any idea wat may be the cause of it ? .......

the accessories shop ppl says its sound from the amp ......

any idean how to solve it ?

perhaps reduce your amp gains,u can try.

check amplifier grounding also, as well as the speaker wire to the tweeter, maybe shorting somewhere, or else amp output problem. check also if passive xover location is near power cables, or even the ecu..

funkydog,
with so many possibilities that you listed, it is easier to use 'muting plug' and trace the problem. You can make yourself one by following here:

Perhaps you want to tell us what amp you are using and type of RCA you used. There are many possibilities of hissing sound starting from equipment to installation errors. I have that problem before and solved after changing good RCA cables and good amplifliers. Cap ayam RCAs have very low noise rejection quality hence the hissing sound could be from the noise as a result of electromagnetic field discruption. Cheap amplifiers have low level of signal to noise ratio hence reducing the gain may help but you lose clarity and details. Hence, tuning is the best option for you to optimize your set up before you start to change your equipments although with limitations.
