My battery is loacted in the back, I was runing a 150amp link fuse .But is there any real reason for this ? There is no fuse when its up front. Thanks

 

Hell yes.
You have at least 8 feet of wire between the engine and the battery.
If you ever get in an accident, or the insulation is ever damaged, you basically would have a welder set on the ON position untill the battery dies. It WILL set anything flammable on fire, including the carpet, seats and just about the rest of the interior of your car.
I forgot to mention, you want the fuse as close to the battery as possible.

The problem with having the fuse at the batter in the back is that it would have to be HUGE in order to take the current needed by the starter. Remember, in a stock setup, the starter is unfused from the battery, but the rest of the car is fused. To be truly protected you would need HUGE fuse in the back and then a 150 up front after the point that you tie the starter in.

 

when you run any wire from the back of the vehicle that carrys that much amperage it should have a fuse/circuit breaker to prevent the car from fire and such. In the stock location the battery cable doesn't run that far and it also doesn't have to pass through any metal bulkheads. I recently relocated my battery and I found that a 200 amp breaker that is normally used in stereo installations was sufficient to supply cranking current for the starter with my headlights and wipers on.

 

put two 150 amp fuses in parralell and run wire under car not inside

 

thats a good idea, but one thing you have to think about is that the wire itself is a giant fuse and if the fuses are too large the wire will be the first thing to go instead of the fuses. max fuse size should be dtermined by wire gauge. the fuse is more or less there to protect the wire.
