Required Electrical for an AQ200d @ .5 ohms.

Well my electrical load at full tilt will be around 500a when that's all said and done, my front battery has 120RC and 55ah, so now how do I calculate how much battery power I will need in the back?

Well that depends on time and duty cycle. So the truthful answer would be impossible to give if this were mission critical power delivery. Since you have the option of simply turning it down when you see the voltage drop, it's really not a problem. You will never draw 500 amps without letting out the magic smoke. The ah rating means this (how much current can be drawn from the battery for 1 hour before dropping to 10.5v) Now, if you get to 10.5v your amp will certainly blow. We're looking more like > 12v. So, this cuts the current you can draw for an hour and keep your amp alive in half... or the time.

So, you have a 55 ah and 500 amps of draw. You still need 445ah worth of batts to keep your amp alive for 1 hour of playtime using batts alone (assuming there is no alt and it's a constant tone.)

If it were ME, I would do a HO alt (at least 160 amps at idle) and 4 group 31 batts in the back. Remember, the batteries cannot recharge if they are constantly discharging. They are not capacitors and able to almost instantly recharge between bass notes. They take several hours to recharge after discharging several hundred amps. No matter how many batteries you add, you're only buying yourself playtime. Not higher voltage and not indefinite playtime.

It ALWAYS makes your amp perform more efficiently and reliably to upgrade your alt. After you see how many batts you need to just keep your amp alive, you should start to realize that an alt is NOT more expensive than a bunch of batts. Especially once you factor in amplifier repair costs.

 
No I'm running less than 3kw. 151 on music is not easy no matter what equipment you're using. Also, don't pretend you have ANY clue what I paid for my equipment. Don't be jelly brah. You've been proved wrong now just stfu and learn something. I actually HAVE done it in practice. Maybe you making your theory a reality is why you can't hit 150. Just a thought......
Edit: and also this is not the first time I've done scores like this. It's just the first time I've done it with so little power. Get your facts straight pal.
Nice job on ducking my question. //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif You scared brah?

And no, a single cab with a 6th order trying to put up numbers is impossible sealed. Outlaw all day long though...

I like when people answer my questions.. Will I be okay running the two strapped with my alt, front battery and 1-2 20ah shuriken batts?
The amps will mainly want to draw from the rear batt bank, so I doubt those will do the job well. I'd get a Deka or two for the rear.

Lol obviously not. I called YOU out remember? lol. Doing a 151 on music isn't easy no matter how much you spend. They are still just subwoofers and amplifiers. Try doing a 151 on music with less than 3k watts. You will die trying because you're an idiot. I also don't have a peaky burp box. I can play from 35hz to ~60hz without dropping below 145 sealed. I can burp in the 153's now and I'm upgrading a little. Again, you have no idea what I paid so the question isn't relevant anyway bro.

a sixth order in a single cab? got pix brah? What is your ratio and tuning?

You still haven't said what equipment you are using, so anything you say is irrelevant at this point.

Blowthrough, and see sig

You didn't ask what I was running.

I am running 2 DDz 15's and a dd z-se. For music wired at 2 ohms. For burps wired at .5. I rise to 2.34 on my burp freq.

Where did you get the dimensions for this box? I understand you wanted a pretty flat response but... this is off. Is it a 6th order bass reflex or a legit 6th? How much port area?

My H.O. will do 130 @ idle and I can fit 3 g31's in the space I have available. I think I'm going to try that and I almost never run at full tilt.

 
Like I said, if I had subs with arguably the most powerful motors on the market that retail for $1400, I could be in the 50's all day long too. Especially on lower power, considering the motor is so powerful on these subs. And regardless of what you paid, that is what they retail for.

Sounds like a good idea. If you have a voltage gauge installed at the amps that you can see from the drivers seat( you can run it up front) and a clipping monitor built into your amp you are good to go. Tough to blow things like that. Just make sure your amp voltage NEVER gets below 12.6v and the clipping light doesn't get solid bright for more than 1 second at a time.

I just don't think you could. A 6th order totally decimates any efficiency my added motor force gives me. I'm running a ported box. You're running a bandpass. Your argument does not hold water for anyone that knows what they are talking about.

It's not flat by any means when modelled, but sound VERY flat to the ear. Series tuned, 30 sq in per cube for the rear, around 128 front iirc

What does the type of enclosure have to do with anything? //content.invisioncic.com/y282845/emoticons/*******.gif.a649d21efc0d1fd4890a6428166586c1.gif I was merely stating that in single cabs, you gain exponentially when the cabin is not sealed, and this is moreso with the 6th order.....

Your rear chamber is a little too big and your rear port is WAY too big. Series tuned = bass reflex. Might not make sense until you do it, but drop to 4 cubes in the rear and about 80-100 sq inches of port tuned the exact same. You will gain.

I have a fuse holder with a gauge so I can glance over my shoulder and just check it here or there and yeah, the AQ's will have the clip light.
