I went to get a box built for my He2s for a usaci comp because i wanted to see how i would place and i was offered to borrow a RE MT 15 and get a SPL box built for it... anyway im just going to run the MT off my T30001bd for a quick spl run but im not going to have many electrical mods just yet (ill have 2 of the big3 done along with a AGM deep cycle battery) So im wondering if it would help putting 2 marine batteries in my ride for the spl run? USACI allows 2+stock battery so im thinking i can run the agm i have as stock and the 2 marine batteries as well. My only concern thou is the marine batteries have a much lower cca rating then my current battery so im wondering if it would even help? anyway ill put the specs of the batteries i have and let me know what you would run

NGT Extreme AGM = 750 cca

Interstate group 31 marine battery = 600cca

interstate group 34 marine battery = 550cca

stock Lead Acid sealed group 34 battery = 600cca

theres no such thing as too expensive when it comes to upgrades like that, because imo if you are gonna spend to upgrade then do it correctly rather then be a cheap ass ricer

The more juice your amp sees the more power it will generate.

right but by adding weaker batteries into the mix im afraid of acutally loosing power.

and the reason i posted CCA's is because the AH of the boat batteries isnt posted on the label and i didnt search for them

You won't be losing power. You will be adding cranking amps to your system which in turn will lessen voltage drop, which in turn makes more power and lessens the chance of clipping your amp.
