    I see that your subs are dual 4ohm, with two subs that can bring your final load down to 1 ohm if wired parallel. Your amplifier is 2 Ohm stable, at low power your typically not going to see an amp go into protect, but once you start turning it up the amp will go into protect, or blow the output. That is one solution. Another thing I can think of is adequate wiring & proper ground, your amp has a recommended 4 guage size, if your using a smaller wire it can starve the amplifier of the proper voltage it's intended to run off of. As for your ground, check the end opposite the terminal, if you see discoloration or any melting going on, then you have an improper ground. The most important part of any system is by far the ground, alot of problems can be solved by checking your ground.

    I hope some of this info helps.

    Those subs have 2 4 ohm voice coils . They can be wired for 4 ohm or 2 ohm. If 2 ohm, the 2 subs will present 1 ohm to the amp. It looks like this amp is 2 ohm stable. You need to make sure they are both wired for 4 ohm so the amp sees a 2 ohm load. The amp is protecting itself against damage. It's very likely getting really hot too. Hope this helps.
