Electrically supporting 16,000+rms

[Godsmack 361]

Great thread.

My only issue is going 15V on componants in car that are prolly designed between 14 and 12.5 volts...........could 15 volts let some smoke out??

Just checking as I am unsire here

I have duel alts at 16.2volts no smoke most car volt meters don't even see red till 18volts you will be no where near that @ !5.5.Will work fine on 1- 4 batteries.No worries mine cars not paid off wife would kill me if I fried it.

I talked to Memphis tech support yesterday for a bit about my problem. The guy told me that they love high voltage setups- even for daily usage all day long. He told me that if I was using it for daily the amps would still perform better on a 16v setup with the alts set around 17.5v. I might just turn them about 17.2 just enough to keep the batts charged and turn them up for comps around 18v- does anyone see any problems with that idea? Thanks

I really have been trying to get around it, but I suppose there's no reason I can't run about 800rms off a yellowtop and 130a alternator for my mids/highs and the memphis 4ks (which from what I've also been told will put out much more with that high a voltage even 5krms+ ) on 3 dedicated 16v alternators with a mid/small battery bank.

Please someone tell me there's less into going 16v than I think..

16v alts

16v batts

+ and ground wire run seperate for this setup?

Isn't the actual chassis of the alt grounded to the vehicle?

Does anyone with more experience than me see a reason not to do this?

And does it sound like a good solution to run 4 16v batteries and 3 200a alternators? Thanks for the help guys.

If you were to run stand alone alts. seperate from your car you could do the 18v alt and leave it on your batts.If you use the kinetic 16.9volt batteries you will need to charge them around 18.9v for a full charge. HC batteries need about 2.8volts per cell to charge there are 7 cells in the 16.9 I'm pretty sure.Only thing with the higher voltage batteries you will have less storage capacity than their 2400.Hope this helps.

Thanks for the info on that, it helps a lot. I wasn't sure I thought they charged around 18v at the most, but I was told by someone they floated around 16.8-16.9. Will there be any problems running the batteries at 17-17.5v with only turning it up for comps? I would be afraid to go over 17.5 daily, and even though I wouldn't be taking full advantage of the equipment it should be safer for daily usage, right?

I have been told by several people that it doesn't matter if the batteries have less storage- that I will need fewer batteries to achieve the same thing with a higher voltage setup, and that's sort of what I'm counting on. Thanks for the help, now I just need to find someone who can sell me powermaster alts- since advance is the only local dealer and they don't carry the alts I need. I thought I had a guy who could get them for me but I can't get in touch with him and the next closest place is about 180 miles away

Alright! I'm ordering the 4 alt bracket from iraggi this upcoming week, as well as 3 powermaster 200a alts with adjustable internal voltage regulators (easily changed from the rear of the case). Advance auto can get them just 15 minutes from my house

450 each with warranty from a reputable business, so I'm not going to complain. Then I'll be switching my yellowtops to 4 16v batts and seeing what these amps will do

Thanks for all the different input guys, even if it didn't answer my exact question all help has been appreciated and led me in the right direction (I think).

What time is that thing Sunday?

I still want to invoice my opinion, but I'll just share it with you in person.

The one in dillon, or CCU?

The CCU one I'm going to "roll in" is 9-12 and the show is 12-7. I'll probably be there for the show, maybe slightly before to help carolina audio setup if they need it.

If you want it right you should do a duel set so you can run one at 18+ you need to charge at the least 1volt more than the battery if not you will be under charging your 16.9volt set up.Not good under charging will cause storage issuse and can limit your compacity.If your wanting high current set up for comps 16.9v 30sec. burps will do but for daily your batteries won't be able to get enough current to keep up for daily driver.This was my own lesson learned.Hope you get your alt awnser I'll see if I can get some options from Scottie.

Well the guy with memphis said a 16v setup was fine, but to keep it around 17.5v (just going from what he told me, but now that I think about it he didn't say don't go higher).

What do you mean do a dual set? I will have the factory alternator running the 12v setup (car/mids/highs/cd player) and the 16v alts on JUST the memphis 4ks.

I'm not sure I understand fully, but do you mean I shouldn't run 17-17.5 volts I should run more to them? I understand not getting the full potential I could at 18v+, but it should at least be better than the 12-13 volt drops I would get with a 12v system shouldn't it?

I would rather see full batteries on a 14 volt than half on a 16.9volt. (In general) If you charge a 16.9v battery at 17-17.5v your amps will only see 16v you lose around a volt through your system.When your car is off and your batteres are at rest they rest almost 2volts less than they were charged at so you would be at 15-15.5v (note a 16v battery is acuality 16.9 alot closer to 17v than 16v)

I figured I would adjust it so the amps actually saw around 17.5. If that means I lose a volt from the front to the back I guess I'd be charging them at 18.5. I'm going to be using the alts on the 12v setup I have at the moment until I can buy the batteries- who knows if it works good enough maybe I wont go 16, but I'd rather try it than wonder what if. Would 17.5 at the amp and (from what you're saying #'s wise) 18.5 at the batts be enough?

18.5 to the batts is good for the 16.9v batteries just check with memphis on the amps.Do they mean 16.0v or an actual 16volt charging set up which is really 16.9.If they say the amps will take it sweet run it at 18.5 and let-er wang!

Just called tech again just to make sure- they said that a 16v setup was the best way to go from their testing- especially for burps. But on a daily setup try to make sure the amps get less than 18v. The tech said worst comes to worst if it's too much the amp either wont turn on and you'll know to turn down the voltage, or will could go into protect.

[chrisminner 0]

I would hate for you to spend that kind of money on a worst comes to worst reply.18v from the alt should be within their range then.I myself don't trust 16v set up for daily it will get hot quick and is really hard on amps and alts in general.

[tejcurrent 13]

I really originally was turned off by the idea, it just sounded a bit risky, expensive, and dangerous to the equipment compaired to the 12v, but several people now have told me the benefits outway the negatives. hopefully I'll be able to get the alts and bracket within 2 weeks (I don't know the turn-around time for Iraggi), then I'll run 12v and see how it works. If I'm not satisfied I guess I'll make the switch.

It really just depends on what your goals are and how much you want to spend. As with most things better at first always more money to keep up maintenance.

thats more so dependent on whether the amp and alts are designed to handle the extra voltage, some are, some arent.

[chrisminner 0]

I'm really curious if anyone is running A (real)16.9v system can help.For burps its great but I want to know how it does as a day in and day out daily slammer.I have ran a 16v set up and I really turn it up daily. Everything would heat up after 3 or 4 songs at full volume.

[tejcurrent 13]

TOTAL change of direction:

I've done a bit more research and talked to Dom Iraggi on the phone. I'm obviously a little worried because of all the mixed feedback on him, but I'm going to go with him instead of powermaster.

I'll be getting 3 of his 380a alternators and at the moment running my factory 130 on his 4 alternator bracket.

paypal works quick! I payed at 2:38pm, and at 2:42 they called me to authorize the amount.

I'm just going to stick with the 12v system, if I go 16v it'll just have to be a dedicated burp machine.

Missinglink, I talked to you on the phone a little bit ago, and I really appreciated the info. As soon as I get the alts and test them out I'll most likely be calling and getting my module.

Thanks for all the help everyone.
