Voltage drop problems

So i just upgraded my system up to 2 sundown sa classic 12”s on a sundown sia-2500d, and upon install and bumping the speakers i noticed i now have voltage drop, with my headlights dimming when they hit (which isn’t too much of a problem for me personally), but when i turn them up to a certain point my head unit will cut off for a sec and then turn back and and play like normal once its been turned down a little. Now i still have to tune the amp to find where the amp needs to be, but the question i have is will this stop my head unit from cutting off
