battery to the boot?

[as_cool_as_u]

How easy is it to move your battery to the boot? im a sparky but automotive sparky is compelety different so it doesnt realy help ...so how do ya do it? and also does it make much difference for powering ur sub/amp?
Thanks

Put the battery in the boot, put a circuit breaker on the positive of the battery and run a couple of runs or 4ga or a run of 2ga from the CB to the front where you'd have the battery positive terminal usually and ground the battery in the boot somewhere. Easy as that

^^ 100A breaker
make sure its secured well, dont want it coming loose in a crash.
but yes, it is pretty easy. Wont make any difference for power sub/amp.

100A might not cut it... Measured a mates old bluebird and it was drawing a touch over 100A on starting. I had a 140A in the Levin and had no trouble with it. Try the 100A if you wish, but you might end up having to get a bigger one. Depends on the car (well, starter really)

running huge leads from the boot, wouldnt that be shitthouse when starter comes to suck like 200A?
ore does the fat wire compensate for that and make no diff?

[Lloyd]

Fat wire can carry more current, wont get hot with the excess current, wont lose voltage across it.

well, i wasnt basing what I said on theories or BS like that. Perhaps I should have specified what engine i did it for though.
It was a 4age (1600cc)

As a rangi temp. job before buying a breaker I had a 60A fuse between the starter and batt. It didnt blow, started 2x daily for a couple of weeks, it was fine.

I dont really care about the theory of it, I tried the 60A thing just to proove 100A would be ok. The theory clearly doesn't apply as the starter only draws that peak current for a second, not long enough to blow anything
(again, dont come at me with "but fuses blow reallly quickly, thats what theyre designed to do!" - I've tried it, it works)

The reason I chose the 100A breaker was because of the convenience of the switch (as opposed to a fuse, which has to be unscrewed to disconnect) and 100A was the smallest size I could get.

Come on, look at the wire going to your starter, is it bigger than 4ga! mine was bloody tiny, u think that little thing can handle 200A for any reasonable amount of time! (for longer than a 100A breaker?)


EDIT: yes it depends on size of starter, what type of car u got "as cool as u"??
