- Supplemental batteries, as explained in this video, arre used in addition with other primary batteries for the ability of keeping extra power. It is important to knwo when it is the right time for you to install an extra battery, as well as knowing how to properly install it. It is important to understand the relationship between the battery and alternator when considering adding that battery.
In this video, Jp gives us a quick rundown on a frequently asked question, what is a supplemental battery? He also answers when it is you will need one!

JP, I know some of us might find the info redundant, but I personally love that you haven't forgot that new faces are joining us bassheads every day, little videos like this are what they need to keep down on the heartbreak that can come from trial and error!!!! Keep up the great work man!!!
It helps in my setup in my ride A HUGE HELP ON POWER ON DEMAND AND FUSED DOWN 5 AGU FUSES. P.S SAFETY FIRST BASSHEADS...........
Love my Sundown subwoofers! definitely have a supplemental battery hooked up to alternator and car battery
Great video JP. Always making the down4sound difference. 👍🏾👍🏾
I had no clue how to hook them up. I thought they get connected to your main battery so this was super helpful
I'm new and this is a big help I have been seeing second batterys on builds lately
Does a lithium require anything extra? Like to keep it from overcharging the battery or demanding too much from the alt? I just bought a battery isolator and have a 150amp alternator. I’m about to buy a secondary battery and I’d prefer to buy a lithium but don’t want to upgrade the alt just yet. I saw that a 100ah lithium’s recommended charge is 50 amps. I’m looking at getting a 100ah lithium or a similar size XS AGM. Any input would be great!
Several questions, big 3 to XS Power AGM battery under the hood, then dual grounds and hots from alternator to two connected D4S LTO 6.0, Then hookup all amps to the D4S LTO. Am I correct? Also for a 10,000 watt system, Taramp MD 8K 2ohm running two Zv6’s bridged to1ohm and a 2K Phoenix Gold on mids and highs, will two D4S LTO 6.0 be enough with a 250 hp alternator? Thanks for your reply.
How would this info change for a hybrid vehicle? There has to be a way to improve the sound in hybrid vehicles.
Hi, I have this 390A alternator. And if I got 2 D4S LTO 6.0 batteries in the trunk is it enough to power an Incriminator IX6.1 Reserve amplifier?
So I am pushing 3,400 watts if I upgrade my battery should I upgrade my alternator to a 240 amp alternator .. I am trying to stop dimming lights and yes I have done the big three upgrade any thoughts on this would be awesome thank you..
Alternator to supplemental battery, but how does it connect to the amps and what about the wiring from the starter battery?
Jp love you vids but have a question do you ship to southafrica?
Audi a7. Do i need alternator upgrade or add a battery?
By adding a battery does that put more stress on your alternator?
I run both batteries parallel with an isolator. I'm confused about what you said about hooking both to the alternator. I have the big 3 done, 2 platinum AGM batteries with stinger isolator, factory 130 amp alternator, skv2 1500.1 amp, 2 evl 12s. Every wire is 1 awg ofc. I know my power isn't impressive but I've never done this before and hooked this up myself in an 09 maxima. Boss head unit too. I'm new to this and always wanted a system. I do want to install a high output alternator but the only one I can find that seems somewhat reliable is JS alternators. I can't up the amp till I do that. It is hitting pretty good and voltage never drops below 13.3 since adding the second battery and isolator. Btw, I'm dying to hear a system like the Tahoe. Never heard anything like that before. Thanks for all your videos and help. They've helped me along the way.
Your doing it the right way running parallel with isolator. It's the same thing he's saying of the alternator. Because your primary battery is already connected to alternator in order to charge. So you charging it in parallel with the primary battery. Make sure you have a fuse from positive battery to other positive battery at least a 200 amp fuse 😊
So I got another dumb question. Can your supplemental battery be too big? Not in actual size but can I put an xs series d3400 on a 2000w rms system?
I think what folks are asking is which is better. Running your power wire from the rear battery to the front battery or directly to the alt? I run individual wires from alt to each battery but ive been curious if that is better or to connect both batteries together and then connect to alt?
Someone please answer
I believe it depends on the alternator. Sometimes you can only run power from front battery to back battery then to amplifier.
Doesn’t matter. If the batteries are wired in parallel, theylll get charged equally. There’s no scientific answer to whether it’s better if directly wired to alt.
@@ATownPyro that’s the thing. I have each battery with it own individual 12v wire ran to alt but I don’t have my rear battery wired directly to front battery
@@wetdookie3808 it is still getting the same power either way you look at it..
Most people run them directly battery to battery.
You probably got your answer already considering this was 11 months ago.
I'm have a positive going to each of my batteries straight from alt .is that good too? I noticed you always say to wire them in line.
That's fine! Tomato - tomata!
If I have a 800w rms system and I have a xs750 and a less than a month old acid battery...can I not add the xs battery to the car as an auxiliary?
Hey, I want to hook up a 1500-watt Kicker amp to a 2015 Toyota Camry, do I need a supplemental battery for only 1500 watts?
🔴How often should i charge my xs power agm battery for my car audio system
You should also talk about bigger cables from battery - to the ground, ground to engine. And Battery + to charger and starter. At one time these was called 3 point update.
You mean like this? th-cam.com/video/bm2f0UMQGj0/w-d-xo.html
@@THELIFEOFPRICE Yes sir, but you should have more ground than positive in engine bay, or gasoline and new diesels could ground them with critical engine grounds.Extra ground for chassie and frame is not an bad idea (floating chassie)

Thanks for your reply.
Ok, what if the second battery is not in your daily driven vehicle ( weekend only ) and you keep the second battery charged. Is there still a need to hookup to the alt ?
Want ti upgrade my alternator but don’t know which will fit. I have a 2002 Toyota 4Runner.
I assume if one goes to an alternator company's website they may have some way for you to ask about it.
I get it needs hooke up to the alt, but do you need a separate wire from the alt to the back or can you just run it in parallel with the main underhood battery? Example alt to main battery, main battery to supplemental battery.
Yes at least an 8 gauge wire all the way back just for charging
Supplemental 🔋 does NOT need wired to alt independently, just to the main battery & then that circuit is completed by the wiring already in place between the factory battery & alt.
Although, you would want to upgrade those wires to gain efficiency! Aka, BIG 3!
Also, preferably upgrade your alt, cause it's now working harder! 💪
I have dual runs 1/0 guage kicker ofc power ground 2/0 nvx brand big 3 have a kenwood 8405 has 60 amp fusing for mids and highs and taramps smart 3k on 2 12 evl skar running around 1.5 ohm how many amp hours do i need currently have xs d2600 and Duracell platinum h7 agm so i got about 130 135 ah also have 250 amp aftermarket amp in my 07 scion tc shouldnt the factory 100 amp alternator fuse pop with having a 250 amp alt now? When im going 2/3 tilt i go from 13.4 volts to 12.4 i dont have dimming lights just wanting to have more than plenty amp hours so i dont drop so hard cause i do see like 11.8 volts also if im going hard on certain bass notes are harsher than others
So the batteries are in parallel?
So from alt (+&-) to primary battery, then from primary battery to supplemental batteries and then from supplement (+&-) back to alt? Or wiring from alt to primary to supplemental?
Great Question, It Sounded Like He Said That! 🤔
Other than upgrading your alt & the wires running to /from it, you do NOT need to run additional wiring from your alt to your new supplemental battery!
Run your 12v + wire from your main 🔋 to your trunk / supplemental 🔋 & put a fuse at both ends.
Ground your supplemental 🔋 in your trunk.
You can install a battery isolator if you want, but that's optional.
JP the goat
So I can't run 2 of the 6.0 in the back by themselves off my 2nd alt, they have to be connected to a agm atleast
So my headlights are dimming, my voltage is dropping below 12.5 when trying to go full tilt. Big 3 already done with 0g. High output alternator is my next step?
1 Sundown Audio X v2 15
4k @ 1ohm
4k amp with stock alt should drop to 10 Volts easy so you need a autotek or mechman alt and a titan 8 in the back and titan 8 under the hood so you can either spend 1500$ and have good safe lithium or build a big headway bank that does alot of power but doesn't last for 400$
Can’t I jus run a positive off the main battery to my back ones and ground it to the frame ? The front battery is hooked to the alternator
That's what I'm currently doing. No big 3 either
My setup in my car is like that and with the BIG 3 and 5 AGU fuses though out my power runs AKA SAFETY FIRST..........
@@________GHOST________ ok sweet I was making sure I didn’t do anything wrong
Unibody with cars are held together with spot welds and adhesive, its not as strong of a ground compared to bolting the ground to the frame rail on a truck. Running the ground wire from the front battery to the rear battery just insures that you are getting 100% of the potential of the current flow
@@andyrajkumar6138 that’s where a bunch of people mess up and it does make a huge difference I believe anyways.
I just learned something 😅
can anyone help me out with what secondary battery to choose i'm trying to decide between an xs power D975 and the Sundown audio sps 1500 both are $220 but the xs has 35 ah and the sundown has 47ah and the xs has a max amp rating of 2100 amps and the sundown 1500 amps (not sure if max rating means much considering it doesnt when it comes to amplifiers) but i cant find much at all on the internet about any sundown batteries and i think it might be the way to go because of the ah it has but i know xs has a rep for being really good in car audio secondary batteries and it has quite a bit higher max amp rating, it's also 10 lbs lighter. The setup i'm running is 2 skar evl's and i plan on getting the nvx xad14 3000 watt rms full bridge amp to power em.
I'm new to Car audio, but not new to Lithium ion, or Lifpo4 batteries etc. What I find interesting is no one ever mentions that having a car alternator connected to a lithium battery without any type of low voltage or high voltage cut off or BMS (battery management system) is dangerous. If people are going to connect a lithium battery especially one that is not meant to run off a vehicles electrical system ( I know they make some drop ins but they have a BMS built in for protection) "newbies" may not know that there is a difference when it comes to those types of batteries. I made this comment because in your video you have an 8AH lithium battery next to an alternator and made no mention of how to safely use these types of batteries in conjunction. I understand it was a Q and A that you answered, but the answer is not as simple as you made it out to be.
Can you get another battery without getting the alternator or should you just get a alternator by itself first to see if it helps
Or would the isolator be another option if you just get the battery?
Alt first... Re-evaluate... Then 🔋, if needed.
Hey what do I charger my LTO 6.0 Battery to before I install it in my car. But one thing is that I can't charge my battery right now. Because down4sound never sent my charger in my order. I'm still waiting for it. And still no response from them. All I got told is it eill be here. But I've been waiting for it and do far no email saying here is your oder tracking number. So beware before ordering your merchandise. 1:11
Yooo!
Bro my dad told me about you, you were his friend when y'all was younger, his name is Gary Wayne Manus & his wife/gf name is Heather Thomas/Manus
I just got the dual alt bracket this thing is nice.. can I hook two different amp alts together together, ones a 270 and one is a 400… or do I need to keep them separate from each other
Curious to know the same.
I'm pretty positive you can run them off the same pulley system so long as you have no slipping (belt slipping) or anything, I was under the impression the only thing you would need to be careful of is having a 14v charging system mixed with a 16 or 19v charging system, you cannot run those together but even then I think its on the same pulleys being turned by the same engine, that's all they're mounted up there for anyway, to be turned by the engine rpms, I believe they just simply run the power wires from each alt separately as needed if they are seperate charging systems... I'm not 100% sure tho im all youtube taught / whatever experience i do myself lmfao
@@zanechristiansen well my thing is I’m sure the 400 amp is gonna charge around 14.8 or so after it’s hot the one I have now is still running off the computer at 14.4 which I’m changing over to the pigtail so I can wire them both together and not be controlled by the computer but still I didn’t know if one is charging at less voltage then the other one would that hurt anything or would it just balance out… I actually asked on one of mechmans videos to see what they say about it also hopefully they get back soon
@@chrisfiske oh yea I guess I didn't even think of that lol.. I wouldn't risk it. it may be a few "points" of a difference off, but I think over time that would over work the "bigger" "stronger" whatever, alternator you know, I'd definitely want them both charging the same, but like i said, I'm all youtube taught anyway lol so I'd definitely want someone elses advice if I were you lol
So mechman replied back and said stack em up it didn’t matter so for anyone wondering that, you can stack whatever you want to together as long as it’s all the same voltage alternators as in all 12v or 16v…
So run from the alternator not the main battery? Someone help me. I thought it was off the main battery.
Main battery
Jp. You need to hear my truck. I have four 4518rs. shit is ridiculous..
I like the “How not to be a Hater” part of this video. 2:15
I want to know where one of those little batteries hold my $5,000 Watt amplifier from sundown can you let me know
For a few seconds that’s it. It’s good for a burp that’s it.
So do you run another wire from the second battery to the alternator?
Will a high output alternator damage your stock battery on a daily driver ?
No
What I'd like to know is which is a better move; replacing the factory alternator (might have bad brushes) and adding a big 3 with it, or do i have a friend custom fabricate a alternator bracket and add my custom high output 320 amp Apex a voltage regulator and a bigger belt and just charge directly to my supplemental deep cycle from it to completely bipass the stock alternator and battery?
If you want the higher charging voltage like 15+ volts then add the second alternator dedicated to only the high voltage. The stock alternator would then charge only the 12 volt battery and to run the car electronics
It more hassle to run higher voltage since you need high voltage batteries and amplifiers
does d4s reply?
These videos are me replying 🙂
@@THELIFEOFPRICE anything on pcm controlled alts ? I got a h/o alt in my 2010 Malibu with 2 back batteries running a taramps mf 5k my start up voltage is 14.7-.8 but after driving it goes down and floats at 14 how can I fix this ?
Yes, until you need help! 😂
I got your battery and that shit is bussinnnn
