A red led indicates that the amplifier is warming up.I checked the conections and everything seems to be ok, I've a 10" Jack Hammer JH 4510 Sub Woofer installed to the amplifier which worked so good when some days ago. Now my amplifier is having this issue... Does anyone round here could help me givind some advice on this issue?

Check the speaker connections from the amp to the box and inside the box to the sub. Its possible these came loose from vibration. Also gently push in on the sub. It should move freely and feel spongy. If it drags or is stiff the sub may be bad. Use an Ohm meter and test the sub. There is an Ohm rating on the sub (usually 4) and it should be close to that. Also check the audio in. Maybe the amp/sub combo is fine but there is no sound going in. Use an MP3 player with a 3.5MM to 2M RCA cable as an input. Start with the volume all the way down and SLOWLY raise the MP3 volume.
