Connecting Optima for stereo only

[Topaz]

I am gunna have 2 batteries, the one under the bonnet and one in the boot for stereo powa. The battery under the bonnet at the moment is a 360CCA, I think.

how do I hook up the second battery?

I am pretty sure it has to connect to the alternator so that it charges while the car is on (forgive me I am a n00b at this). So if assumption proves me well I can just connect it to the fron battery because that one is already connected to the alternator, right!...and ground the Optima to anywhere on the body, right!

............have I just created this thread for no reason?, I'll post to be sure.

is the above right?

If you don't want them isolated from each other just connect the two positives to each other and the two negatives to each other.

ahhhh u could do that or.....

get 4 gauge wire travel it from battery from front to back and put isolater solenoid about 30-40cm from batter from the same line. use 4 gauge wire from negative of rear battery to a solid point of the chasis in the boot somewhere

i think thats about it oh and use 2 fuses one at front battery and one on rear battery

thanks SERIES_II, thats what I think I am gunna end up doing anyway....

where do I thread a piece of cable from the front to the back running through the firewall?, I could see no points of access through it.....

are those isolator solenoids what stop the sudden backward surges of power?, had a mate tell me about those yesterday and that I needed one for my setup

Sorry I didn't realise you wanted the ability to isolate them from one another.

only 4 gauge? Shouldn't you run 0 gauge wire?

thats a good point actually, I think I will get 2 Gauge for it as I am running 2 Gauge from my Optima to the amps and 2 Gauge ground....I always thought 0 Gauge was overkill
