4 10s youd probably be looking at 1.2-1.6 per 10 depending on the subs, so you could make it within spec. But how much money are you wanting to spend. Cone area goes only so far when it comes to number of subs IMO.

Like Ray said, 2 12s. You'd need more space for a proper 4th order for that 15", not to mention that powers pushing it. Cone area+motor force = . Edit: Thought the XXX line did over rated. Maybe thats at higher voltage.

Moneybags (the SD rep on here) was running two 8 or 12ks daily and now runs two 16ks daily @ 18v with no issues. Boiler used the 16ks. Theres a handful of other guys on here that use and love their SD 8-12ks. Very few use the 16ks daily though...I think skittles may have clamped his 12k and its putting out far more than his last amp with less voltage drop. (maybe you had more drop or higher rise than the AQ , just dont see a 4k amp being louder than a correctly functioning/correctly powered 8k+ amp)

The D3100s may read relatively the same, but if his front is resting slightly above the rear then he would probably need to throw them on the charger. Ive seen new batteries sit for just a few weeks and drop .2 or .4 and need a quick trickle charge. No biggie.

Still 'd.

The alt, plus 2 XS D3100 should be more than enough... only 2 XS D3100!! Id get rid of your current rear batteries and put the biggest one you can fit up front, then one XS D3100 in the rear should do it, but for that kind of amperage draw, you may want two. You may want to consider new amps though too...I think the SD 12k has a max amperage draw of 1000 amps...yours doesnt put out near half as much power as that but is over half the amperage draw?

The alt, plus 2 XS D3100 should be more than enough...

^^ That too. What about with the car on? You may want to try removing one battery from the bank at a time (still having two connected counting front) and see if you still have the issue, or if it gets better at all, or have all your batteries checked by autozone or the likes. But as I said..3 batteries isnt a lot. You have maybe 180 @ idle amperage. Then you have say 50 amps from the car. So your system from the alt is only seeing 130 amps...your batteries have to make up the difference. Three batteries wont make up for that 4-500 amps of power.

:DAMN: I think he needs his camber checked.

What are you resting at? You could also have a bad cell in one of your batteries causing your bank to drop hella low.

IIRC these amps can pull like 600 amps of current each...not very efficient amps. 4k watts is no joke, but your electrical should probably keep up...id say your problem is amp efficiency mainly.

Buddy who has his own wood shop catches deals like this all the time. Craigslist is Awesome for tools all the time. He picked up a 8 foot table saw for like $300 with a 7 hp motor. He just picked up a lathe/mill for $200 and a jointer for $100. Lucky bastard. Just looked at your username too...the guy I was talking about is named randy. Randys' get it all.

My post asks about a 14v "set up" not a 12v set up. My system charges between 16.5v and 16.8v . And on there site it says working voltage 8.5v-16v. I was simply trying to see if anybody has a stable 14v set up! Thanks Tho and it says on 16volts you will get 2,500 watts its on there website Yea i saw that. So that means its stable between 16v-16.9v? I want to know if its safe to run my amp beyond 16v? Best bet is calling aq and asking it's protect limit. Some 16v stable will actualy go up to 17ish, some saying up to 16v is it's max.

Price shipped to 63701 for the set. We can Pena ly work something out.

Doc said I couldn't play lacrosse for atleast 6 months after I broke my collarbone. I started playing full time two months later. There's a reason true career is a "practice". In all seriousness, get well soon. And you may be hearing from me on thoughts about my wall design.

Lol 8 would be fine...only thing id use 4 awg for would maybe be if you had 4 or 5 subs I'd use 4 from box terminal bolts then 8 for the subs themselves. Doubt many if any dubs would fit 4 awg. A lot don't even fit 8aeg.

What backwoods said...I'd probably give it closer to 16-18. Would prolly shoot closer to 5 foot net. Mind if you increase your port your net will get smaller of course, so make the box bigger to compensate.

Turn your gain way down, not full. You're clipping like crazy. As for the box, wedge style boxes are fairly easy and using aeroports may be easier as well.

No. It's that easy. Knowing how much port they will like is te difference. Torres will tune the port the way you tell it to. Knowing WHAT to do and how much port to give the sub is the difference. The Torres calc is only as smart as the user using it. lol, maybe he should go get advice from these experts... because everyone around here knows that it really is just that easy... this calc is perfect for every day boxes, now 4th, 6th, 8th order shit, yeah, you wouldnt want to use it... I'm just curious how he's spending 10k on a system but doesn't know how to design a box himself and thinks torres was useless. Seriously op, I'm curious WTF you though Torres was for. To calculate box volume for the box? LxWxH.

No. It's that easy. Knowing how much port they will like is te difference. Torres will tune the port the way you tell it to. Knowing WHAT to do and how much port to give the sub is the difference. The Torres calc is only as smart as the user using it.

Why so many...I'm making my peak and seal Facebook group now. Us > you. Both our products add mass...but were cheaper.

How does he need a new alt with maye 1500 watts of power? Not even sure if that hifonics does rated. I am running a 1k watt Rockford at .7 ohms and 400 watts to my highs and don't drop below 12.4 full tilt for hours with 1 d5100r xs battery and the big 3 done. It's probably the sub and amp getting hot...

Actually with series you add the resistances in the circuit and with parallel you add the reciprocal of the resistances and then take the reciprocal of the sum. It just so happens that typically you are using multiples of 2 of the same coil and coincidentally it doubles or is cut in half. You could actually wire a bunch of different coils together, in the same circuit, that have different impedances and it would work, not well but it would. Hypothetically if you had 4 coils (1 ohm,2 ohm,3 ohm, and 4 ohm) wired them all in parallel, you would have a total resistance of .48 ohm nominally. Now take the same coils and wire them in series, you would have 10 ohms. You would also think that each coils in these configurations would get equal power... THINK AGAIN. The power that each coil gets would be directly related to their impedance. Why the fuck would someone out of the gate who's confused need to know that? That's what you call giving too much information. Confusing confused peoples not te way to go, it's called giving a simple retort to simplify a complicated situation. Not someone who wants to show they know something. Thanks for the useless information noone asked fore.

Nothing like cummin or strokin. Om nom nom.
