Is my system plan overkill or missing anything important to run correctly?
My plan is to run a 300 amp high output alternator and run a big three with 2/0 knukonceptz oversized ofc wire and fuse the alt at 600 amps and connect my front XS power D3400 Agm battery to the rear identical D3400 with fused knukonceptz oversized 4/0 and a 500amp smart isolator in between I then from the rear run 3 1/0 gauge ofc wires all fused at 300amps each to a fuse block that can handle my power and out of that 2 1/0 wires to my sfb8000 which i will pull 3200rms at 4 ohms for 2 subs fused at 300amps each and from the distribution block another 1/0 wire that runs to a fused distribution block that has 3 outputs 2 are fused at 150amps and ran to my 2 audio control epic amplifiers which are going to pull 800rms at 4 ohms for 4 mids and the other 280rms at 4 ohms for 2 tweets. the third run is fused st 100amps and is ran to a 100amp relay which has a fused turn on wire from my fusebox and goes to a 12 output circuit where i can put mini fuses of any amperage in. the relay is grounded to the ground block in the 12 output circuit and the negative of the 12 output circuit runs to a negative ground block the same size as the other large one which then has 2 runs of 1/0 ofc to my sfb and 2 runs of 4 gauge ofc to my amps and 3 runs of 1/0 back to my rear battery. I also am running a dsp off of the 12 output circuit and all the turn on wires for the amps are from the 12 output circuit as well as grounded to it. I am receiving signal from a lc5i pro which i will tap speaker wire from directly behind my hu since i cannot replace it and that is the basics of the whole setup I also have a blueprint layout ive made to keep my power wire seperate from speaker wire to minimize electrical noise as much as possible. I just wanna know if i can cut back on anything and still make it work well so i can chop prices since this setup will cost me well over 5000$
