how many batteries to power amp

[Orion xtr pro]

i have a 2002 f250 super duty diesel with 2 batteries under the hood that have 850 CCA.

i plan on getting a dc audio 5k amp to power 2 15inch XL subs.

would my stock batteries and adding 3 kinetic batteries, in the back next to the amp, be enough to power the amp to its full 5,000 watts.

or would i have do a Big 3 Upgrade to be able to achieve a 14.4 volts from the batteries.

any suggestions for the best setup, to get the full 5,000 watts from the amp, are welcomed.

thank you,

Brandon

You should get an H/O alternator. Doing the big 3 will help but only a little. For 5k yoou should look at adding maybe 1-2 kinetiks and getting a H/O alt instead of the 3rd battery.

Do the big three, no question.

What is your alternator rated?

you NEED a high output alt. no ifs ands or buts

edit: stock alt is 105 amps i believe.

We recommend for installation

• 1 upgraded battery under the hood

• 1 extra 800ci battery in the rear

• Minimum of two 0 awg ran from the front battery to the rear battery

• Both 0 awg power and ground inputs on amp must have 0 awg ran to them for a total of 4 runs into the amp

• Upgraded aftermarket alternator

• Dash mounted voltage meter

jeez running 5k.

youre gonna need a beefy alt. 320 would be nice. and I'd say 2 group 31 batterys plus stock
