i am so damn confused

[scratchy]

Ok, I finally found a battery today. Its not the best, but its all I could afford.

Its deltec 105 ah 750cca I think

In front I have a puny little 45ah stock batt, which aint worth a shit.

Should I remove the front batt and replace it with the new deltec, or should I keep the tiny batt and add the deltec as a secondary batt.

Bear in mind that funds are REALLY low and I dont want too waste money on unecesarry(sp?) or unworthy stuff.

I DONT have money for a isolator and I cant really afford alot of cable.

So should I just whip out the old credit card and get some more cable too run the deltec as a secondary or will the difference be not worth it?

Also, if I run the deltec as secondary? how will I wire it up?

[Guest SyKo13]

I'd run the bigger batt as primary then just parallel it to the secondary for more current

[scratchy]

so how will that be? big one goes where? connected how? to where?  :-[

[Guest SyKo13]

Put the + with the + to the +

Put the - to the - to ground lol

[scratchy]

Then the big one in the boot. Then just + from the big one to the amp. and - from the big one too the amp.

dont I need too ground the big batt?

theyre saying put the big battery under the hood and put ur stock battery in the back. connect the positive from the front battery to the positive of the back battery. then positive from the back battery to ur amp. ground the back battery to the chassis but a different ground than ur amp.

[scratchy]

ahhhh. Ok, im such and idiot.

What would be the logic of putting the small batt in the back?

[Guest SyKo13]

Amp has its own battery, yet if you're going to parallel you're going to need about 17ft. of cable, 17ft of cable = very high resistance, so just think twice about putting it in the back.

If you do put it in the back, just grab some 1ga. cable and you're good, 4ga. won't work due to the high resistance it will create.

[scratchy]

we dont get 1gauge here. I think im just gonna pop the big one in the stock location and remove the stock one completlly >

Yea, to ship stuff all the way over there must be a real bish......
