Do you know your Alts are making power? Play the system loud and clamp your your alts.
I have 4 3.5ks @.5 each running off a single mechman 220a. With some caps. Rarely drop below 12s. I shut it off and charge up of I see 11.x.
Something is up, the problem is not the lithium

Is this the truck that did a 161 bassboxing qualifying with BOTH doors open?

I prefer number 2
I cant fuck with mariachi guys, they are to cool. Except the accordion players
lol I was really hoping this was going to end with you giving rolex the finger slamming the last note

I run my zv4s on a 3.5k each daily. Never had any issues...if you care about numbers and cost isn't an issue, go ns3. If its just for daily listening, its probably not worth the extra money over a zv4
-
so basically i'm limited because of the vehicle I drive since no one makes a dual alternator bracket?
Pretty much. I'm in the exact same boat. Now I'm trying to run 15k rms, still on the same 240a mechman with 8 banks of supercaps. It works...okay...but I'm not happy with it. I'll be finding someone to help.me fab up dual alts this winter.

Take my build as an example when I ran a ddzse, 7k rms. I ran a single mechman 240 alt and 6 xp3000s.
This allowed me to play close to full songs full tilt before giving it a break. With that setup I could demo for 1-2 minutes balls to the wall and stay above 12 volts. In the amount of time it took to switch songs, voltage was back and ready to go again.
240 amps of alt is really only good for a 3.5k amp max unless ypu start adding lots of batteries and or caps.

Agreed to set gains correctly as all have said.
In addition, i'd try turning your subsonic filter down...assuming you have a decent box for those subs, you probably have no need to run the subsonic at all.

...specifically the word removable. Have you ever tried to remove secondskin?
I would think this product would work better for more permanent applications. Haha and now i'm off to find a reason to order some...

alcohol is not illegal.. weed is legal in some states but its still illegal to the feds.. so just because Colorado and Washington legalized it dont make it legal.. wait when the Feds starts busting their assess and their local state laws cant help them in a federal court
to the point. if i was a parent i woldnt allow my kids in a forum talking about weed and alcohol. im sure many parents would agree with me. alcohol, drugs and cigarettes should have their on place in the 18+ section.
Haha I don't want to get into a discussion of states rights vs federal government power here.
The question was about influences on under aged kids and Alcohol is still very illegal for anyone under 21. If a picture of a cartoon Monkey rolling something green into a cigar is a bad influence to kids I would certainly think that real pics of bottles of alcohol and real people drinking it would be the same.
Personally, I don't really care. I don't think a picture of anything is going to "influence" someone to go do something they wouldn't already but its an interesting topic to discuss...And I think we agree haha
you have your views i have mine.. kids see their parents drink alcohol in occasions more than they see them do drugs.. you can socially drink a beer, you cant socially get high 2 major differences but then you have those idiots who abuse alcohol
i can care less though because i do either of those.. alcohol is only bad when its abused. drugs are always bad even if not abused
^I mean...you definitely can socially get high. The vast majority of recreational users never smoke alone. They smoke and hangout with their friends in the exact same way they would drinking some beers. Personally, I would't and don't do either around my kids. But, I don't want to clutter up the RPP anymore so I'm out!
I will leave you with a closing thought though to your underlined opinion: Is alcohol not a drug?

that said, i still think anything weed related should be in the 18+ section in my opinion. weed is not bad but the promotion of it here can be an influence to underage kids. like i said i have nothing against it but just like half naked pics of girl need a section the weed needs its own. i see nothing wrong with people using it or even seeing people post about it but i can see how a parent wouldn't want their kid on here if all they see is weed propaganda. at that point the forum is not aimed at all ages and just 18+ members. even though i see no harm in it i dont think its something parents want their 12 year old seeing in this forum
Would you also agree then, that any post with alcohol in it should be banned form the public part of the forum? Because there are tons of those everywhere and its just as much an influence to underage kids...in reality those posts should be only for a 21+ section too right?

Thanks for the reply, Hunter right? I was actually texting him about this earlier this week lol.
He has banks of 7 caps and is charging at 16.2. So a slightly different scenario.
Id like to avoid having to buy 10 more caps to run banks of 7 for now but if its my only option it'll just have to wait til next season :/
-
I recently sold off all of my xp3000s in favor of running banks of supercaps. I have 8 banks (soon to be 10) of 6 caps now so my max charging voltage is 16.2V.
I mostly compete in IASCA classes which require you to have a battery under the hood. So I can't totally ditch batteries but I want to charge a bit higher to squeeze as much out of my system as possible.
So my question to the XS crew is: can I run a d1400 daily under the hood but charge around 15.8v? Will this damage the battery over time or will I just see a little less performance out of it than if I were in the mid 16s?
-
My xp3000s were at 13.1 after two weeks sitting I'm my garage off the charger. Two weeks later now and they were at 13.05 when I checked last night.
-
^Agreed. Also if you are more interested in musical output and only need to play down to the mid to high 20s you don't need to tune super low. 32-34hz would be fine.

Lol this was going to be my exact answer. The amp producing 1000 watts at 2 ohms has to be producing a voltage at the output terminals 4x that of the amp making 1000 watts at .5 and it only has to output 1/4 of the current. I'd guess the energy lost through heat in the coil and wiring of the .5 ohm setup would result in enough power loss to at least see a small difference on the meter.
1000W is 1000W. I'd guess they would be the same. However factoring in real world things like speaker wire impedance and connection impedance I feel that the higher voltage setup would win since the current would be 1/4 of that of the 0.5 ohm setup. Power loss = current x current x impedance. So for the same speaker wire impedance the 0.5 ohm system would loose 16x the power of the 2 ohm system in the speaker wiring alone assuming both systems use the same amount of wire.
didnt read more than 5 words
a amp doing this at that... vs a amp doing that and this..
well fuck....
Edit- you think you can GAIN one the meter? or chill on the electrical,... or get louder by wiring this with that and coils, with this and that?
I honestly don't know what you are saying here man but if I can figure it out I'll try to answer...

lol thats not chris just fyi

Lol that last parts the key. Drunk driving Mario kart used to be a classic prefunk for me. You have to finish your beer before you finish the race otherwise you automatically lose hahah

My 64 is the only console I own, super smash bros and Mario kart FTW!

Gonna go take a tour of this place on Friday for one of my Graphic Engineering classes. Should be pretty sweet!
Thats cute Did you tour the EI production facility too? I bought one of these for work, I just finished getting it up to production speed a few days ago, pretty cool piece of equipment no doubt.

Interesting...Can't say anything about the internals but the + and - plates on these are certainly different than the Maxwell caps I run. Looking forward to some comparison tests between the two and whether or not the XS can be wired up in a bank with the Maxwells.
I very much like that they are black too, the blue does NOT go well with the rest of the rodeo lol
-
^I think the results would really depend on the amp. Some amps will put out ALOT of power past 1% distortion (IIRC thats the percent the DD-1 detects) but they will still not yet be driven into clipping. Other amps will distort and clip at the same point.
I would liken this to the certified and uncertified amp dyno modes. I would imagine amps that are further apart on these two modes when put on the dyno would have a much greater variation in score.

Did you load test the d3400 after pulling it out?
