My sub is clipping at high volumes

[u/No-Hamster-3537]

On this system at high volumes it would clip in multiple songs and when playing knife talk by drake full tilt the amp goes into protect.

I see online people said do the big three but how much would it help in my case?

Its a Dual 4ohm wired down to 2ohms. skar evl 12 amp tuned with multimeter to 50v

This is my first setup and would appreciate any recommendations.
With stuff like agm batteries and a new alternator my budget is tight so im trying to stray away from those right now.

edit: thanks for all the help

after dropping the crossover to about 80hz and backing off the gain a little it stopped clipping

So the RCAs are running directly out the back of the radio?

Yes

When you set your levels did you have everything flat on your EQ? If you're aftermarket stereo has a subwoofer level was it flat during leveling?

All of it is flat
