Side Cowl Cover Removal? Or Easier Way to Get 1/0G Wire Through Firewall?

So I decided to start the wiring tonight for my aftermarket subs/amps/speakers tonight on my '17 JKU. Of course I ran into a problem right away: getting the wire through the firewall into the engine bay. I was using hole on the passenger side that is filled with insulation foam, and the wire fit fine into the hole, however on the engine bay side there is a piece of metal right in front of the hole (kind of like the greek theta) dividing it in half for some reason.

I was thinking I could either bend that piece of metal upwards above the hole to get the wire through, or just cut the piece off right in front of the hole. Either way, doesn't seem like it could cause any functional problem.

Sooooooo, is there an easy way to get those side cowls off so I can gain access? I've tried googling and keep coming up emptyhanded. Or, is there an easier way I'm missing? I already have the thicker gauge wire, so that's what I'd like to use for my grounds and power.

Thanks in advance for the help!

I highly recommend this spot here, as there's a lot more clearance and it routes nicer.
