F32 Harmon Kardon Hissing Noise

anonymous101 · 09-24-2023, 11:18 AM

This noise is coming from all 4 mid range speakers. Like static/hissing noise even when I am not playing anything on high volume. I am not an audio expert, but I wouldn't think all speakers would go bad at the same time?

On high volume 50%+ some songs have a static noise come up every now and then on certain frequencies.

Is it the amplifier?

Any tips would be very helpful. I would like to avoid upgrading for a new Bavsound system or Alpha one and spend 2k if I don't have to.

Still have to install a downpipe, and get the license and the tune.

Speakers don't hiss, electronics do. Loose connections between the HU and amp are one possibility.
