Suggestions on grinding noise from Dayton HO390
So I just finished my nearfield sub build using a Dayton HO390. Installed the woofer today and am temporarily using an old Buttkicker 1000 amp to test it out. I will order another amp soon. Anyway as soon as I connected the amp to the woofer I get a grinding noise from the woofer. The woofer is brand new. Comes and goes and I haven’t the slightest idea what it could be. Maybe coil or possibly the amp. Any ideas appreciated. The sub sounds awesome.
