Wiring 2 Amps questions

I posted this under a different name and I would like more feedback. Even though the one guy the responded gave me some good information.

I'm setting up a bunch of equipment from an old car and some new stuff into my 2013 Camaro. I have a couple of questions;

Is a power distributor going to be okay with only a 4 gauge going into it and 2-4 gauge wires coming out?

In order to wire two 12s that are dual voice coal speakers down to 1 OHM a series approach (+s all attached to one amp output and s attached to one). The amp is setup to handle 1 OHM?

Do I need to worry about my cars alternator with the 2 fairly high powered amps (1800watt max at 1 OHM and 800watt max at 4 OHMs)?

Does anyone see anything else concerning about the diagram I'm posting?

so first off, the MAX power rating means nothing. you want to base everything off RMS power. with that said, you are fine with the alternator.

I would run 2 gauge or bigger (maybe 1/0) and then split to 4 gauge. if the power wire is too small then you will strain everything including your alternator and your amps. imagine drinking a soda through a coffee stirrer (tiny straw). you strain a lot and get little through it. if each amp needs a 4 gauge power cable, then how will enough power pass through a piece 4 gauge and then split into 2 pieces of 4? if the amps are adequate with 8 gauge then you can run 4ga back and then 8ga to each.

you are running your subs in parallel. how many ohms are each coil? i will assume 4. i do not know if your amp can handle 1 ohm would have to check the stats.

When using a distributor always start with a larger wire, preferably OFC. To be honnest it is probably easier just to do a single run to the back with some nice 4 gauge ofc wire, Throw a decent AGM battery in the back and run 4ga to each amp off the battery. Make sure to get a good ground in the trunk. Ground the battery to the chassis, and ground the amps to the battery. Hope that helps
