Recently my speakers have been sounding harsh, but only sporadically. Basically, the music will sound clear for a bit, and all of a sudden become somewhat unclean and harsh. It also happens vice versa, where I will turn on the sound system, it will sound off for a bit, and then all of a sudden, clear up. I really can't pin it down, so I was looking to see if anyone has ever dealt with something like this.
The components in my system are:
AudioFrog GB10 Tweeters
AudioFrog GS60 Woofers
JL Audio W6V3 12" Subwoofer
JL Audio HD 600/4 Amp
JL Audio JD 1000/1 Amp
Mosconi 6 to 8 Pro DSP
Kenwood DDX9904s Deck
I'm playing through a Samsung Galaxy S10, via usb c.
I've tried switching the sound service: both apple music and spotify.
Turned off all sound effects on the headunit (Kenwood has a bunch on by default).
