power question

[icy_chris 18]

if i'm planning on putting an aq2200d to a fi btl 12 daily 2ohm wired to a 1ohm load and ive done the big three and planning on adding 2nd battery in trunk the box is 2.5ft3 tuned to 35 would i be safe with my stock alt its 110amps at idle and 160 @2000rpm?

You should be fine but the only way to tell is to install it and go from there, if you had the cash and wanted to get an HO Alternator in the future it wouldnt hurt neither so its up to you. Get a voltmeter and watch your voltage then go from there.

ok i got a volt meter at home i will try that thank you

If you use ohms law you can figure the max output of your current system by multiplying your volts by your amps.

I've got a 200 amp alt and haven't got anywhere near utilizing all of it and I'm running a sundown saz-2000d.

The last time I was clamped I hit around 750 watts. My voltage dropped pretty low- around 11v but was some where around 70 amps. I never push it that hard on daily use. That was taken at about 1200 rpm idle.

Aside from that you have to consider running your air conditioner, wipers and headlights for normal usage.

I think you will be okay. A second battery will help alot since you've done the big 3.

If you find your lights dimming after you get your install done it means you probably should upgrade your alt.

Then your alt is broke....... :-/ at 11v your alt should be working it ass off.

At least mine does, my 240 does around 227 at 12.4v and 1,400rpm.

ohh comment pwned turner!!!

i have no air in my car lol and the only reason i'm asking is i cannat find a h/o alt for my 98 sunfire that is under 600 to get it to canada

I think you will be fine with your alt, just test it often to make sure it's still putting out power.

thanks for the input can't wait for my build to be done so i can crank the tunes again it sounds so dull with no bass

the alternator is only going to put ou what you call it to do so. If you are pulling 227 amps at 12.4 volts your system is putting out 2800 watts.

Like I said I was only pulling 750 watts so my alternator only had to put out so much current. My shit isn't broke man- it just means I've got tons of overhead.

I really hope all of these numbers you are posting are based on measurements of the actual voltage, amperage flow, and output of amp/amps that you have taken.

And not just you knowing the math behind it and assuming it's all correct.

Example 1a: 227amps x 12.4v = 2,814. So, based on your math, my vehicle needs NO power run any of the systems it needs,and also that my amplifier is 100% efficient.

Example 1b: You said your amp was putting out "750" watts, based on your math since you were at 11v pulling 70amps, it should be making 770. But then, again, the vehicle has no power to use and the amp would have to be almost 100% efficient.

Both of those seem pretty implausible, but I'll go with it.

Example 2: "If you use ohms law you can figure the max output of your current system by multiplying your volts by your amps." Really? It's that simple...............

P.S. Your alternator will work at "max output" until the unbalance in supply/demand is met. So, your "200" should have been damn close to putting out 200 if your at 11v.

And all this was done a 2a.m. Sorry for any mistakes.

the cool thing about everything is the numbers don't lie.

Your alt isn't ever goin to run at max output unless the max load is called for. If your alt can only put out a max 180 amps and 15 volts then I'll be pucking damned if your amp ever pulls more then 2700 watts. When I say system I mean all current load on your electrical system not just stereo system.

That's how you figure your max output. Your not going to get 15v so this max is actually higher.

I wouldn't just pull some shit like this out of my ass. Yes- like I said- last time I was clamped.

That means I had meters on my shit measuring my numbers.

I don't remember the actual numbers for each measurement but if I dig deep it was like 10.98 volts at 66 amps. The actual total wattage was 768. I did 143dB at that time. Whatev

In essence I was only utilizing 35% of my Alts rated output. Like I said my shit ain't broke I just have lots of overhead.

To op- sorry bro

Wait what? lol. What company made your alt? You may want to ask for a refund. 1200 rpm isn't idle either. If you drop below your batteries voltage and down to 11v then your battery is more than half way depleted and your alt is maxed out if it cannot keep voltages up. My girlfriend's 240 amp DC Power alt output ~140 amps at idle, 700-800 rpm, and sits at 14.8 volts hot with stereo on blast (1500 watts) , all lights on, and AC full blast.

[adamt 1]

I have been talking to some people and I am partially wrong here.

The voltage I reported was my amp voltage and not my system voltage. It is the ac voltage output from the amp that was 11v.

my numbers are still the same 11vac output on speaker leads and around 70a on positive speaker lead.

Where I am right is the output on my alt I only used 35% of it's output. I am getting together with some people soon to measure amp output in watts and see what it does in ratio to system voltage off the battery.

I apologize for my error. The cool thing is-the numbers don't lie as longas you got the right numbers.
