How would I go about testing where in lines it drops?

Under hood I have 1/0 ofc grounded to stud welded directly to frame. In rear I have 1/0 ofc to stud welded to frame then goes to bolt coming through floor board. Then both caps have 4ga ofc to that ground bolt. And amps have 4ga ofc to distribution block and grounded to that bolt. And with Alil change to my box I was thinking about getting 2 pioneer ts-3020pro 12s

They are the mxd-1 amps so they are capable of 1 ohm. And I have 2003 Silverado ext cab,and want to keep the rear seat still stock and usable. So the under seat boxes are quite limited with mounting depth. It’s my daily and not trying to go competition by any means. I just like really loud good sounding music lol. Slowly building up as I go but I’m not to knowledgeable on really good stuff.

My apologies,I should have been more specific with what I have and with what exactly is happening. 320 amp alt,yellow top batt,big 4 all 0ga ofc. Main power wire runs back to block that splits to 2 5farad caps. Ea cap is individually grounded,then the caps are run to 2 marts digital 2000wrms amps. The ea amp powers its own 12” alpine type s. Subs are wired to 1ohm. When getting on it pretty good,like one click on volume down from how I set my gains I get minimal voltage drop. From 14.7ish will drop to like 14 on hits. Then once go Alil more on volume and it clips. My amps have clipping lights,huge voltage drop. Like down to 11-12

Noob to bigger car audio and forums in general. But figured I’d ask more knowledgeable people than me about things I can’t figure out with simple online searching. I am having clipping issues and major voltage drop on big bass hits. Which I want nice big bass out of system. Not sure if I’m overpowering my subs which causes clipping then voltage drop? Hopefully someone out here what’s to discuss what’s going on and where I can start next to fix the problem. Thanks in advance!!
