do i need an extra battery to run a AQ2200 an AQ4x90

simply put your going to burn the diodes up in the alt eventually..

the only reason it's not so prominate is because the battery generally discharges before you can burn the alt..

the ah or amp hour rating is how many amps in one hour the battery can putout to completely discharge it..

and the most important thing is discharge/recharge times is esr or internal resistance between the plates in the batteries..

if your going to get a battery you want one that can recharge and discharge fast..

down fall on them is there longevity is shorter simply because there not made to discharge slowly..

just do your self a favor spend 550 on a good alt that's going to power the entire system without having the battery to discharge..

lmfao..what do you guys do for a living?

your not going to benifit from adding batteries..

if you want more power without voltage drop or end up burning your alternator upgrade your alternator..

if your having to rely on the batteries to power your electronics the alternator has to try to supply the vehicles electronics and charge the batteries..

so if you want ur batteries and alt to prematurely wear out keep adding batteries..

it's in believable this idiot would suggest you add another battery..

you sir get the golden star of fail. everyone knows batteries are needed. an alt can not run a complete. or we would start our cars and run the radios off the alt.

So, how would you supply say a 10Kw system on just an alternator? Let's say the alt is a good 350amps. You will supply the accessories with about 60% of that, so say 210 amps usable. Now, that will supply about 3-3.5kwatts alone@14.4v. You will need at least 2-3 of those for supplying a 10kw system without discharging the batt. Now, add the batts residual supply for watts per hour from say a 120ah batt. You get about 1728watts per hour @14.4v and of that, about 1210 to use for residual due to constant drain. Add the batt supply to one of those alternators, and you need about 5 batts to go with one of those alts at 350 amps for supplying a 10Kw system. Do you understand how batteries can make a difference as well. As I said before, all components are important, hence an electrical "circuit". All components work together. Would you rather get 5 batts or 3 alts? Not sure, thats relative. But this is just an example, not for the OPs setup. And obviously other losses have to be considered, and can actually be defined more precisely than this example if measured instead of calculated, but this proves that batts and alts work together to provide power for the system, and adding batteries is more simple for most people, if they have the wire to do it, you can run extra batts all day long and back up what the alt does not provide. BUT I see what you are saying about burning out the alt...THIS can happen...no doubt, so again.....both have good points. Just trying to show you that the "system" is called a system for a reason. The charging system is a charging system for a reason and it all works together.

HEY PAPERMAKER!!!

the battery is made to start the car, nothing else..

the alternator is there to recharge the battery.

if you want to spend 500 fillers on 150 pounds of battery go ahead..

the alt will charge the eventually..

while I'm not going to deny that batteries don't provide power they are much more limited and must be recharged..

you think they use big battery supplies on Riga or to power cities?

no they use adequate sized generators..

ive personally used 4 kw on a 110 amp alt and 2 hc 2400s..

but I've used big enought alternators to supply the entire electrical load and now voltage drop is a thing of the past..

I could run 10k on 12 2400s and a stock alt but that doesn't mean it's the most effective way to do so now is it.

power out=power in

sure you can compensate but what happens when you cannot supply them..

what happens when the alternator has to constantly charge the batteries..

like I said if your going to do that might as well use deep cycle because your gonna burn any low esr battery up..

btw we all know that most 10kw systems rearly draw 1/2 of its potential output because of the impedance rise and dynamics of the music..

this is what rfs 15000 4 channel is based off of..

just trust me when I say you want to upgrade your alt..

if your not willing to do dual Alts a good battery like the hc 2400 coupled with a 250 amp alt will supply 5k..

just not like dual 250 amp Alts..

lmfao you increase ampicity no to lower resistance..you not going to experience voltage drip through the wire 3 feet long at any voltage..

I was making a general in a nutshell "Thats what your doing" statement... Honestly I'm on a phone I'm not gunna type out a huge long list of everything you go through and what it gunna do for you... I'm not an engineer or anything else... I went to school for CAD, architectural design, animation, and graphic design... Now I run my own asphalt company... Ya I'm sure

You could school me on this cuz it's my hobby I'm just saying from experience in my car he doest need to drop that kind of cash on something for a daily system...

Tony if I were you I would take that down with a quickness or you will soon be on vaction from here.. Just a heads up..

this forum is funny...

he's not hurtin anyone..

he likes going full retard..

I do too!!

if you have the money get you a high quatitly alternator ..

you can get one for the same price as another huge battery and it's more rational..

btw fellas im never an *** until someone calls me out..

they did. hell i did .you act like all a battery does is start your car. no. very wrong. thats like saying it just turns the camera on.

it runs the electronics in the car. what is an amp? AND what happens if he wants to play car off to test like 99% of us do. having an alt aint helpin anything when the car is off to prevent the garage from getting co2 in it.

ill leave it up to the other guys to explain further. it really isnt worth my time to explain something so simple.
