squeel coming from speakers

[ninobrn99 10+ year member]

Im getting an intermittent squeel from my front speakers. What could cause that to happen? I have CDT 61A-25 in front powered by a cadence zrs 9004. Its running off an 8g + straight from the battery and a 8g - on the chassis next to where its mounted. thoughts?

its engine noise also known as alternator whine. its an easy fix to do.. all you have to do is ground the rca's on the back of the radio. or buy a ground loop isolator

how do you ground them? I have two sets of rcas. One for the speakers and one for the subs

 

[ayerun]

basically run a piece of speaker wire from the rca to the ground wire

just splice into each one then?

the squeel is a cry of pain. which translates to "omgwtfbbq , check your wires".

check the sticky thread about alt whine fix take 2.

dont buy a ground loop isolator that's just a band aid..

make sure youre headunit is grounded properly, wire harness, and chassis of the H/U.
