When Amp is powered up Subwoofer makes a Clipping noise when Relay inside amp switches on. Then after that everything is quite until you touch Subwoofer by hand. Amp generates a high pitch Squeaking noise on every frontword movement. When pushing sub backward no sound appear. Frontword movement only. Even if i tap sub with knuckle.Between every tap there is a Squeaky noise.
Long Squeak when Sub is pressed all the way in and released. And short squeaks when tapping cone. No input(Radio)or RCA connected. Thinking it might be Filtering Cappacitors inside Monoblock Amplifier.
It is not 1 of the coils rubbing on Magnet. Did tests with other speakers aswell. All speakers tested makes same noise. Any help will be Appreciated
