Check the wires for short circuiting at the car body or speaker wires. Triple check really everything.
Make sure the connectors are 100% connected to the wires. There maybe some resitance if the amp isn't getting enough power from the battery.

Sounds to me like the amp is going into protection mode. Try placing one sub on the amp with very little gain. One of the biggest reason why this happens is because the subwoofers are wired wrong. What is the brand and model number for your amp?

Are you connecting positive to positive and negative to negative from the sub to the amp? If so, try positive to positve (+) in the far left channel and then the negative to negative (-) on the far left channel to. If no luck do the same in the other channel with one sub at a time. Try one sub at a time, Dont try an connect 2 or more subs to one channel as this would cause the amp to go into protect mode (red light you describe).

Everything did work but kept blowin fuses by the battery. Now a red light stays on, on the amp & the blue/green power lights dont *** on. What should i do?

Check all of your power connections, your speaker connections and battery connections. if all are good and clean (no shorts/wires touching) then try unhooking your speakers and see if the lights come back, if that helps then you have problems with your speakers, if not then amp is bad. I hope this helps ya.

Amp works when beaten

It sounds like you have a broken connection in the amplifier. The first thing to check is the fuse. Sometimes the contacts become weak on the fuse holder and the connection becomes intermittent. Any other troubleshooting would require opening up the amp. Any repairs would require resoldering the broken connection.

Let me know if you have any other questions.
