No room for a 2nd alt. in a Pontiac GP will be just adding batteries and monitor voltage

I have a d3400 battery up front and plan on installing a d3100 in the trunk, BiG 3, 2 runs 0 g. POS. (250 amp fuses) & 2 runs 0g. NEG. to the D3100 parallel. amps: (1) Digital Designs S4a, (1) Digital Designs SS2a (1) Digital Designs SS3a, (1) SKAR Audio 4500.1D (2) runs 0g. POS. & NEG. MECHMAN 270a alternator will this setup be enough or do you have a recommendation?

Stop Whining build it right and buy some more equipment from your dealer hint... hint...
