The amp has two lights a green when its on and a red one when i turn it up not that much it turns red and stops the subs they are ma audio when i connect one it works fine.
Sounds like you're overloading the amp's ability to drive the speakers. Turn the gain down on the amp and see if you can take your volume higher. If you have an independent subwoofer output control on the headunit, check its setting and reduce it if necessary. Also, if you're wired in parallel, rewire the subs in series to increase the load on the amp.

There could be a few potential reasons why you are not getting any sound from your subs even though the green light on your Power Acoustic amp is on. Here are a few things you can check:
Check your wiring: Make sure that all of your wiring connections are secure and that there are no loose or frayed wires. Check that you have connected the amp to the correct terminals on the subs and that the speaker wires are properly connected to the amp.
Check your settings: Check the gain and crossover settings on the amp to make sure they are properly set. Ensure that the crossover is set to the correct frequency for your subs and that the gain is not turned down too low.
Check your power source: Check your battery and alternator to make sure they are providing enough power to the amp. If they are not, you may need to upgrade your electrical system or add a capacitor to your system.
Check for a blown fuse: Check the fuse on the amp to make sure it has not blown. If it has, replace it with a fuse of the same amperage.
If none of these steps resolve the issue, you may need to take your amp to a professional for repair or replacement.
Is your gain all the way up? If it done this before, sounds like your over working the amp. Make sure your subs ohm load is capable with the amp load to. If they are 1 ohm and your amp is only 2 ohm stable, it would beat for a lil bit then go into protection mode to. Check your wires too.
the amp is a 200 Watt by 4 im guessing and its doing that because its going into protection mode unhook the subs if it stops then 1 you have a bad sub or 2 the subs are too much for the amp if an amp is rated 200w per chanel its 200 max about 75 rms or 75 normal constant power
something is shorted in the circuit, or your subs. unhook the subs first and try it again, if it is still in protect then it is most likely the output transistors.
This could be a DC offset condition. Check you manual for what this means. Or other condition. First Disconnect the Subs and try it. If it still goes red then disconnect the RCA's and try it again. If the Led continues to go red after the click then the Amp is hosed. The Click you hear is an internal relay that cuts the subs in after a dely so you do not get the turn on THUMP of the radio at your subs.
Your Amp is in protect. Disconnect your subs and turn it back on. IF the led goes back to green the you have a blown Sub and it will need to be replaced. If the amp stays in protect even with the subs removed the the amp is toast.
