Hello,

I recently plugged my new system with a Sub S-8. I really don't know what is the difference between the two bolts at the rear of the sub. I noticed that the sub sometimes keeps a "hum" when on, any advise on how to set this up?

thanks

Juan 

Hey Juan,

Please log into chat or give us a call and we will be happy to troubleshoot the sub with you, a little real time correspondence is exactly what the doctor ordered for this type of problem.  Thanks!
