You can make anything fit. It just depends on the amount of fabrication you want to do.

That should be a Group 48 battery, which will meet the dimensions of the S3400. The S3400 terminals will be reversed from your stock battery though, so you would just need to extend the cables if there isn't enough slack in them already. I would double check the fitment to make sure it will work though.

The battery is going to supply the power that the alternator can't. You aren't but for discussion lets say your system is pushing 3000 watts and lets say your alt is putting out 100amps at idle. So at idle you are pulling approx 350amps of power (50amps to run the truck) and your alternator is putting out 100amps. The extra 250amps of draw is now coming straight from your battery, because your alternator can not supply the extra power at idle. If you rev up the RPMs, then you will be getting your 200amps and will only be pulling approx 150amps from the battery. This is where battery power comes up big. The chart is a general guide for the average car audio enthusiast with a stock alternator and using the system in a daily driver application staying in the 12V range. With your application you should be able to fit the D6500 under the hood without having to make any modifications, and this would be a good power source for your system in daily driver use.

Yes just GM.

We really do not recommend using an isolator, but if you want to use one just get a good one. The reason we do not really recommend one is that you are always going to have voltage drop coming out of the isolator.

The VCM will not work with the Toyota applications. Adding a XS Battery shouldn't be effected by your alternator.

The work great on stock alts. You do not have to have anything done to the alternator. Just plug and play. They will not work for the Fords.

The VCM allows you to regulate the voltage output of the alternator. You can do this from inside the vehicle and on the fly if need be. You can change the voltage all the way up to the 19V range if you want for a 16V system.

Yeah that will work fine for you. If you are using side terminals, then you will need the Ibar Kit 551 also.

No, 12V batteries when fully charged should rest at 12.9V at least. You can take it to any auto parts store and they can check the battery for you in a matter of mins.

The D5100 and D5100R are options as well to take a look at.

Come by our booth (Booth 23512, Central Hall) at SEMA next week, and check out the new products we have available. I will be out of the office next week at SEMA, so if you need anything hit me up before Friday or the 2nd week in Nov. Should have pics and updates from the show on our facebook page. http://www.facebook.com/xspower

I figured you all would be there.

As big as you can fit and afford really. The more reserve you have the better you will be. You could get the 1005 charger, but we have the new HF1215 12V charger coming out soon which is more compact and is going to be less expensive.

I would run an extra battery in the back to give you some extra reserve capacity. I would recommend using a charger to to the batteries off when you can. This would relieve the stress on the alternator. Do the big three and throw a second battery in the back and you should be good. Is your voltage going to drop.... yes because you are going to be exceeding your alts abilities very quick, but with enough reserve in the back you should be good.

Fully charge the battery and then let it set over night and test it. If it is sitting at 12.6 then that means you are not getting a good charge on the battery. If the battery was bad the voltage would read much lower.

We do not make one for that application.

Those are the correct prices for your application.

The D3400 will work fine under the hood. If you are worried about the increased heat of the climate and engine temps, then you could always put something up around the battery to block the engine heat from it. You could even add in some circulation venting if you wanted to. Easy check to test the battery is check the resting voltage of the battery (when the car is not running) after it has sat over night. If you are in the 13.1-13.2 range then you are good to go.

I did edit my post on the AH comment. I shouldn't have said useless, because it does have some importance but is not the Yes, there is some truth to mixing the batteries. We do not recommend mixing batteries with different chemistry make up. For instance in your case our batteries have a different chemistry make up than the optimas, and over time the bigger XS Power battery will drain the smaller optima. How about mixing same brand but dif. Model of xs battery like d3400 and d3100? That would be fine. We have a lot of guys running different sizes of batteries in the same vehicle and a very common install is the 3400 under the hood and 3100s in the back.

You can figure your vehicle is going to pull around 50amps (probably on the high side), so the 250amp alt that actually does around 260-270amps will work fine for a 3000watt system. For one thing the system is not going to pull 300amps of power continuous and if the system does start to pull more than the alt can produce the batteries will hold you over. You would probably be fine with the 200amp alt, but for the difference in cost between the 200amp and 250amp it makes more sense to go with the 250amp.

Hey Nova, I would recommend a minimum of 4 per SD16KD. If it is for SPL competition, you may want to consider up to 10 D1400's to power 16kw. The advantage in using a 14 or 16 volt battery over a 12v battery is the additional voltage you get to the amplifier. If you decide to use 14v, you will need to make sure that any battery that is connected to it is also a 14v battery, and that your alternator can properly charge at 16.5-16.8VDC.

The D2400 as a starting battery will give you about 2500 watts of power.

That alt will do just fine with that set up.

There has been a lot of questions about charging batteries lately. Lets look at it this way. A D3100 is around $350. A multimeter or volt meter can be purchased for $40 to how ever much you want to spend on one. IMHO it would be a good investment to get a multimeter/volt meter to make sure the batteries are being charged at the correct voltages. Multimeter/volt meters are just good things to have on hand for any electrical situation. You can usually find some pretty good deals in pawn shops on stuff like this.
