Have you confirmed that you have a good signal feeding the amp?
Have you confirmed that the speakers are in good working order and don't have any breaks in the wiring?

If you can point it to me in the schematic diagram I might be able to help you. But I suggest you bring it to a qualified audio electronic technician if you still value it. cheers!

Over current protection turns on when the amp draws more current than normal. It turns on so it doesn't catch on fire. Your amp has a fault, most likely in the output stages. These power transistors consume the most current and if they blow short then that will cause it to go into protection. If it is under warranty take it back, if not have someone in your area try to repair it. What load were you running anyway?

wire the subs if thair dual 4 ohm . in parallel. red to red and black to black. giving it a 2ohm load. do the other sub the same. and conect it on the amp . turn your gain about 12oclock and db level less than 12oclock and your frequnecy around 80-100. and that should work
