Well #1 you must have 16 volt batteries. Cant do it on the stock ones.

#2 you have to have something that will charge at that voltage.

Would two 8 volts in series work?? What about an 8 volt and a 6 volt?? Can I just charge them up right before I run through, on a battery charger??

I don't see why two 8 volt batteries in series wouldn't work.

Some adjustable regulators do 14-18 volt ranges :-)

If you are looking to do 15.9 volts because your amp says it can take up to 16, then do the 8+6 for 14 volts. two 8 volts will, when fully charged, sit higher than 16 volts, and will fry your amp...can you say 4th of July?

Yep...the 8 volts we have on the truck rest at 17.5 volts and on a charger we have had them on as much as 20.1 volts.

Question...y do you want to do this? Also are you sure the amps will handle it? Some amps you will not get a gain from the increased voltage...

The easiest and most permanent way would definitely be to buy Jacobs or Harrison converter, that stays app. at 16V, almost no matter of current draw (except on overload).

If you would go over (theoretical) 12V, you would need also different alternator with much higher voltage than 16V, which can fry (or at least shut off your amp). Cells are not exactly 2V. If they are charged, you will have more than 16V. And if you will go 6V+8V you should buy batteries with identical cells, and new alternator again.

With converter you could enjoy 16V in all conditions, all day long. Not just with separate charger.

And of coarse, you should probably have one alternator for ordinary 12 V battery and one alternator for 16 V car audio battery. I am looking forward to see car with computer running on 16+V. I am not saying, that this is impossible, but is it really worth so much effort?

Just think, for yourself, what is the easiest way: converter or (2 batteries, one additional alternator, extra cables…).

Ducttape: next time buy amp with regulated power supply.

my amps have an unregulated power supply. they have been played on voltages as high as 18V before without a problem. my question is this, can i just charge the 8V and 6V before the competition on a battery charger????? i dont necessarily need to leave the voltage that high for everyday use, just for competitions. will i get the 16V if i just charge them on the battery charger before the competition????? and wire them up to the amps before i run through. i have never added batteries before and i am looking for the most inexpensive way to do it.

ducttape a lot of amps have unreg. power supplies doesn't mean they can take ungoldly anounts of voltage most top out at 16-17vrms

my amp has burped at 17.9V before and did not have any problems. i saw it done by the guy i bought it from. he holds warious world and state records in the MECA SPL league. im not going to play it everyday at this voltage. instead, only when i am competing with it.

what kind of alt do you have? a good one will keep the voltage in the high 13's to low 14's at a few thousand watts. thats plenty for a car amp.

i have an American Bass VFL1000 right now. i compete in MECA SPL and that is the highest powered one i could use and stay in my power class. the guy that sold it to me currently holds the world and state record in that class with it. he is a pro and changed brands so he sold it to me.

also, i have found a battery that is rated at 16V. it has three posts on the top of it. one post is for the ground. the other two are power leads. one of them supplies 12V to the car. the other supplies 16V. will this work to get the voltage i want. also, will my existing alternator charge it since part supplies the 12V power. i currently have the stock alternator in the car. it is the biggest stock alternator i could get.

i have an S-10 blazer. i am looking at the possibility of adding an external voltage regulator to my alternator. will this get the 16V i am looking for to compete with??

high
about the battery- it probably has exrta cells in series with the 12v ones. I dont know how many cells are in them and there voltages. somebody in here will know. but anyways if you measure the voltage between the 16 and 12 it should be 4v.then you could charge the 12v side with like 14.7 (alt output) and the 4v side with (14.7/12) that should charge them equally. find out what for and how those batteries are used. they where built for some purpose.
is the American Bass VFL1000 an amp or alt?
but now you have a stock alt in you car. how many amps is it rated?

ducttape I just asked my boy who sells AB and he says the highest input voltage is 15vrms

If you look in Summit racing catalogs, they have the 16 volt batteries. Drag cars use them because alot of them don't run alternators (due to the tension of a pulley). Now, you will need a way to charge this thing. If you get 3 of these batteries, wire them in series, you will get a "theoretical" 48 volts. 48 volts is what us hydraulic people use to power our stuff. Red's Hydraulics makes battey chargers that are adjustable from 12 up to 72 volts.....think about it

the 16V battery in question is sold by Jegs. it is made by Moroso, and is for race cars. as far as the input voltage on the amp, i have been told and witnessed that it could be burped at 17.8 Volts. i was told it would not hurt it if it was only burped at this voltage. so, with this in mind, would .9V more than the highest "recommended" input voltage really put a strain on the amp????? where did the guy that sell American Bass get his number from?????

as far as my alternator, it is the largest stock alternator i could get on it. i'm not really sure how many amps it pushes out. right now, i only have the one amp(VFL1000) running off of it.

Umm...I REALLY wouldnt put 17.8 volts to an amp. Period. and going over the recommended voltage by just .2 volts can damage it. People dont realize that burping a system is VERY damaging to equipment. (I will probably get alot of feedback for that statement..lol)
If you think about it, you are putting high voltage to an amp..feeding it a hot rca signal, and then pushing hundreds of amps of current out of the output section. If done repeatedly, you will lose an amp or speaker along the way. Ask the guys like Jay Lovelace, Fred Wright and Jeff wright why they carry SOOOO much extra gear with them...trust me, it ain't for no parking lot sale.

Hey what's up Ducttape? Another Nashvillian! I would be careful with the input V because almost 18 V will fry MANY of the amps made today. They are just not made for it. Some will take it though and survive..

Got Bass?

from the product guide that I just went and saw today maximum votage input at lowest gain setting is 16 volts, recomened long term use it 15.5, and then we called AB and they said 15.9 was the max I asked about higher voltages and the tech said that it would go into overload protection mode to prevent the insides from frying. So ducttape I would not suggest running aboue 16 volts, the tech (Jared) said the best is to worry about getting 14.5 vrms

I have a jacobs acuvolt that goes to 16 volts but its only rated at 50 amps. I going to run 8 2300 mtx amps. The mtx tech said they would take 15.8 but i have ran them with the pot turn all the way up like 16.5 volts and they didn't shut off.....my ? is can i use this to charge 16volt batts like 8 of them since its only rated at 50 amps and my alt amps is 140amp...wont the fuse blow and or wont it limit the amps. Is 16.5 volt enough to charge a 16 volt system. Any info from anyone would be much appreciated.

Turbo start also make 3 post 16 volt batts and just plain 2 post batts and they sell the charger to but its really expensive.There in summit too i think and they have there own web site.Shaker and alot of other people use them.
