Another Battery Question

Ok, I have read the topics on dual batteries and I don't quit understand them.  I am going to install 2 batteries in my SRT-4.  One in the front and one in the trunk.  Now I will not be listening to my system with the car off.  With that said do I need a isolater?  How do I hook the two batteries up just + to + and - to -?  Also, do I need a fuse running from the front battery and the back battery?  If so, how do I determine what size fuse.  I am going to run 1/0 for the batteries and 4ga extra ground to my body from the front battery and 1/0 for the main gounds for the batteries.  I would have bought a bigger alt but, I am tring to buy a house and my alt is like 500 dollars and the reseaon I am running the batteries is because my distributor sells them and I got a great price.  The alt I would have to pay full price and I just don't have that kind of money right now to get the alt.  If you would please let me know what else I could do or will this hook up be ok for about 6months until i get the money to get the alt. 

Thanks

Actually I would not use an extra battery if your using the stock alternator, you will be overworking the alternator big time as now its has to try and charge both batteries, run your sound system and all of your cars electronics

I was going to put it in just for future system upgrades.  The stock alt is 135amps so, I thought that would be ok to run the second battery.

your stock alt is fine for everyday type listening.....If your gonna bang the crap out of your stuff....upgrade!

If you get a good isolater, then they will have good instructions as well. They are simple to install.

Just fuse it up good and youll have NO problems. (by that I mean get ready for that eventuall alt. upgrade) fuse it in the back as well.

Where can I pick up an isolater?  Discount Auto?  What do I look for?

I agree with you that 135 amp alternator will work fine. I have a 105 amp alt. running to two batteries. I'll admit this is a strain but I am pulling much more current than the equipment you described. I used an isolator for a long time but actually only for playing the system with the engine running. Just parallel the terminals with good wire and proper fuse. Ground the second battery also. If you do decide to get an isolator make sure it is rated for over 130 amps. Stinger makes several models.

I am running V918XD Visonik 1500rms at 14volt and 500rms Visonik 4ch.  They say I need to run a 275min fuse for those number.  1/0 wire and I am just going to install the one gel for now and see what happens.  I bigger alt is in the budget but, getting a house it taking pride over that right now I just need to get it hooked up before april 16 and with on batt I should be good.

Thanks
