Would this be the proper way to hook up an extra battery? and will the power still be suffcient with using the distro block?

That's alot of fuses. =)

This is a technically acceptable way of wiring your car up, but you will probably find some dead batteries fairly quickly - you really can't wire two different batteries - or the same batteries of different ages - together like that. Paralleled in that manner one battery will have a slightly lower internal resistance than the other, and that battery will drain the other while the vehicle is off - purchasing batteries of identical design and identical ages does negate this however.

I would recommend you get a second Yellow, and wire them up together in precisely the manner you've drawn up above.

Have you purchased that first yellow yet or what? They're might be some more cost effective solutions - what are you running off this charging system anyway?

so all those fuses are necessary? Also im going to be running about a 2500 watt system. And I know i will upgrade my ALT when i get the chance! But for now its just batteries. So if i get a yellow top under the hood and in the back it will do good?

I was also told i should fuse each 4 gauge power wire after the distro block. Since my amps dont have a fuse

Naww - but with two batteries its probably a good bit of prevention. Fuse (or circuit break) within 18 inches of each battery - IMO this is all that is really needed.

This can mean alot of things. What amps are you going to run? Link to the product pages.

We might be able to design you a passable charging system much more cost effectively.

An even better way, as I see it, would be:

1: Two identical batteries, even age. NEVER parallel different types or ages of batteries.

2: Instead of running from the from battery to the back battery, run from the front battery AND the back battery to the distro. You can save yourself a fuse and fuseholder, AND minimize connections between the alternator.

3: This will also allow the batteries to power the amplifiers equally, due to the minimization of connections between the front and the amps. Twice the current capacity, without straining either battery. Longer battery life.

Other suggestions to come as the thread fills out.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Like this... One less fuse holder, and equal load on the batteries.

I think i see what your saying. So i should run 1/o gauge from the front batt into the distro and then run 1/0 gauge from the back battery into the same distro right? the distro does have 2 1/0 gauge inputs. Also if i wire it your way i wont need an fuses for the 4 gauge?

Right now I got a Soundstream pca2000d that does 2000 watts at 1ohm and i got a jl e 6450 that does 75 watts x4 at 4ohm
