@andrewpeel912 I'm not quite sure I have a hgs 12 I no its a servo controlled subwoofer and as far as I no there isn't any options to replace the amplifier plate with another type plate amplifier because of the servo. The only thing I can tell you that might help is there basically the exact same thing. also the spl models velodyne the only difference between the two models is the cross over board and servo controls. The amplifier section is the exactly the same on these models That being said I wouldn't doubt it has the same issues. Hope it helps you. Have a great one till the next one 🎶🎵💯🫡✌️
Did you find the problem? My hgs15 does this also, it's less severe when the gain is turned down

Replace all the capacitor on the amplifier board it should stop that humming problem it's common on the fault with this brand subwoofer 😉🫡✌️💯
