Is an Isolator Needed?


Recommended Posts

with todays high power systems an iso can actually harm you. it would be continually swithching back and forth and also cause extra wear on the alt. where you might use one.....lets pretend you dont have any amps just a deck and spks. wire in the isolator for main battery and auxilary batery. you go camping shut off the vehical and fall asleep drunk while fishing with the radio on(first youve made sure to be in acc not ignition position on the key) now you wake up and are able to start the truck because your starting battery was not drained. do this too many times and alternator dies because as soon as it starts it switches back to aux and spikes because it has to try to charge a dead battery. not good

I use a relay between my front battery and my back battery. It has the pros of an isolator but not the cons. It basically disconnections the link between the battery when the car is off or not in accessory, depending on what power supply line the relay is connected to. I have it on the accessories line so I can listen with the car off too if I wanted too.

The fuses near the batteries are for the wire and not for the amps. The fuses near the amps are for the amp unless amp's fuses are already on the amp. This is kind of basic.

If the amp has fuses on it you still need to fuse your power wire going into the amp in most applications

Thats for the wire and not for the amp. If the amp has fusing on it already, why are you going to protect the fuses that protect the amp? And what applications are you talking about?
