Disconnect all inputs and outputs then restart it if problem persists you have a internal solder bridge youll need to have it repaired by authorized repair shop or buy a new amp at wholesale from this site:

The MRD-M301 is a discontinued model but originally sold for around $250-300. A more powerful current model is the MRP-M500 that sells for around $200 and under at discounted online stores.

Hope this helps.

Powers up but no signal
Check your gain pots as well as audio pre outs on amp. sometimes pre outs will get loose and be unable to make a connection.

Correct settings
I am not familiar with your amp, but any amplifier performs best when the output stage effective resistance exactly matches the load resistance. So, read your 15" subs and find out number of ohms, then set the amp to that number. according to your amp's specs: if you have 2 ohm speakers, you can draw 350 watts from your amp. so purchase 2 ohm speakers
