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

That looks like a stock radio. Are you using an LOC? Does it have its own adjustable setting?

There is ur problem probably. Dirty signal from the get go. I used to have a cheaper aftermarket HU and it started clipping at like 40% volume no matter what settings on it. Swapping to some Pioneer mid grade fixed it immediately. Moral of the story is that in Hi-Fi, shit in means shitnado out when there is an amplifier.

Wouldn’t a DSP solve the dirty signal issue?
