well im about to start my new build some time next week hopefully and im trying to get my electrical squarred away this weekend so here it goes.

i recently recieved my new amp (cactus 5kw), and i know it is going to need alot of juice so my plan is to 1.) upgrade my starting battery to a decent car audio battery (everstart maxx, walmart style now) 2.) do my big 3 in 0 ga (haven't done that yet) 3.) run 0 ga to the trunk 4.) one battery in the trunk for sure (d3100) and possibly another if i need it.

so far my knu koncepts cart looks like this: 2, 0ga amp kits(for the extra wire, 250amp fuses), 4, battery terminals, 2, 200 amp fuse(for alt and rear batt.), 10 foot of 10ga speaker wire. let me know if i need or dont need anything else please add.

also this is the first amp ive owned with two power/ground leads. do i just run a distro-block off my rear battery two 0ga into the amp?thanks

Look into a high output alternator as well.

you wouldnt normally need to upgrade your starting battery. I'm runnin 5,000w of power and i use stock battery.

I see that you didnt mention new alternator.

because of this... i wouldnt expect your alternator to last for too long with that kind of current being pulled.

You will need more batts than normal because of this.

Probably 3 D3100s but the problem is the more batt you add, the longer it's gonna take to charge em all back up.

ive already got a 200amp ho alt for a cop car. but so far my does list look okay?

someone told me a pair of D3100s will hold up 5k fine.

i got one coming, plan on buying a 2nd soon.

5k is plan also.

if u already have that alt, then yes, a couple D3100s is fine.
