@@beatsandwestside yes for one battery but the other stays in reserve when you turn your key the other battery kicks in and helps it turn youre car on and recharge both batteries
but adding a battery isolator will prevent the sub amp from using power from the main car battery. Its just running from the 2nd battery and charging from the main one. The only benefit from that is you now have a very short length power wire from battery 2 to the amp. Zero extra capacity

He's doing it correctly to.. A lot of people won't ground the secondary battery and it will kill their Alternator" or they"ll Ground it to a capacitor thinking that will work! The best way to do it is already laid out have the amp ran Normal get the "Converters" run the power through them and ground both batteries..Also Kids Learn As they get older like me lol! But Most Deff Hook Up A CrossOver for the bass you'll never go without one again And If Yur Doin 2 Batteries Run the Big 3!! Because you don't even need a second battery if you're just hooking up 2 12s or Two 15s Four 10s to a 1000 to a 2000 watt amp Done it!!
Looks great, great detail. I'm curious, did I miss it, or did you talk about isolation (relay, etc.) between the 2 batteries? Or, did you just run them both straight (both connected, all of the time)?
Great video , I just want to make sure , so we have 2 100amp fuse from the front #1 battery to the #2battery on the trunk right? and one more 100amp fuse from the #2battery to the amp.
This is a very clean and robust installation. One question: Would it be slightly better to connect both the secondary battery and amplifier grounds to the same point? With the two separate grounds using either end of the seat belt bracket, I can see a ground loop forming.
Awesome video, very clear! Couple questions though.. Should the fuse from primary battery to secondary battery match the rating of the fuse from secondary battery to amp? Also, does running two batteries require an upgraded alternator on most vehicles? Thanks
For starters, it depends on how many amps you are pulling as the alternator is charging those batteries. So to answer your question, yes. You alternator will need to charge those batteries, so if your system is bigger than your alternator can support, then eventually it is recommended to upgrade.
Yeah, I hear you about the warranty. I would definitely check on that b4 doing any modifications. I'm not an install professional but upgrading your "big 3" makes a big difference with your voltage. If you can't install like a 300 amp alternator see if you can upgrade the big 3. Which is replacing 3 main cables on your vehicle. The batt ground to the chassis, the chassis to the engine block, & the alternator plus to the batt plus. You'll go from 4 ga to 0/1. Plus a capacitor tends to help as well. I'd say go for 1 farad for every 1K Watts of RMS. I know a little bit but it would be better to talk to a pro. I don't know what you're running but good luck and keep the dB's up 😁
Does the size of the second battery really matter? I have a few smaller car batteries in my garage. I have a Mercedes and the battery from the Benz is huge
That's nice and all but I highly recommend equal amounts of ground wire from the main battery to the second battery. Steel does not conduct as well as copper.
Does it make a difference then if you add a second battery even if your alternator or regulator only allows so much wattage to pass through at stock???or this is jus another method instead of replacing a bigger alt and regulator?
hello I wanted to ask you a question: your second battery has the same amperage as the first motor side? example 70 ah at the front and 70 ah at the rear? Thank you.
I like it. The only thing that concerns me is the stock alternator is going to charge both batteries? I'd at least upgrade that alternator. Am I wrong?
Rob J No you’re right. They should eventually upgrade the battery. But like they said it’s only hooked up to a 5 channel so no need to upgrade the alternator.
The issue I have with this set up is you are not using a amp relay. So if the amp battery is low it will cause the main battery to drain down to equalize. It's not that big of a deal but it will cause your primary battery to fail much faster then if you had a relay. Stinger makes relays for cheap
Battery Isolator is good when you want to listen to the radio while the car is off. This is so that if you listen to the radio for too long, the car will still start. If you only listen while driving or the car is running there is no benefit to it. For me it is useful as I have a van and like to hangout in the van and listen to music without the engine running. If I fall asleep or leave the radio on by accident, I know that the van will still start up when I want to drive away.
@@christopherhaynes8633 With an isolator, where should the 2nd fuse be placed after the one up front? Should it be placed just before the isolator, right after the isolator before the 2nd battery or both?
The batteries will end up drawing off each other and shorten their lifespan. Really bad idea unless you have matching batteries. Usually it’s the smaller battery drawing off your more expensive battery.
I have a Cadillac ATS and my stock battery is already in the trunk. So am I basically just hooking the secondary to the positive and negative up to the stock battery?
i hope youve tested your rear grounding spot for any resistance. thats actually a bad spot to ground. having a rear battery, needs to be grounded to a actual frame or chasis. not a added welded piece of metal. but cool video
I don't have my back battery or amp grounded to the body or frame, just one wire from the battery ground to the amp... I use a deep cycle cell that's just isolated.
There should be a switch between the two batteries that will automatically separate the batteries when the car is switched off to avoid the batteries from discharging each other.Obviously the car battery is older than the one being fitted for the audio set up, so what do you think is going to happen?Rookie mistake
andrew shatlaw he is just showing you how to hook up a second battery not how to to build a battery rack fuse is a very important if you want to know how to do that look up other videos
So, if I understand correctly, there are two wires on the positive on the secondary battery, one from the main battery under the hood and one to the amp, correct?
thank you for the tutorial. question: do i need to run a wire from the alternator to the second battery, or does only the main battery need to be wired directly to the alternator?
Question..... Can I hook up miscellaneous stuff to this 2nd battery without affecting other things like maybe having a power inverter next to the amp for when I need it?
Jeff Deering you don’t always have to. If you’re doing a crazy system you might have to. If you have problems keeping up a charge maybe try an isolator first
what about a battery tie down and base box to prevent any acid spilling or corrosion (especially in case of accident)? Least I would do is a plastic pan and a good tie-down.
Hi guys. Great video. I'm learning everything i need to know to install 2 new amps in my car. (my old amp finally died) My sub amp has 2 zero gauge power and ground hook ups. My mid range amp has one 4 gauge hook up for each. (DD audio M4b and SS4b) I'm running zero gauge and upgrading fuses. My previous installer had run the ground wire all the way from under my engine bay to my 2nd battery in the trunk. Was that a waste of wire? Your video here makes running new zero gauge ground wire from the engine bay to the trunk battery look unnecessary. I would appreciate some reassurance that for my application it's ok to ground closer to the trunk somewhere. thanks.
You'd be better running a ground from battery to battery as long as its gauge is think enough to support the current. Copper is more conductive the steel! Also should eliminate posible grounding issues
Your ground should be same as positive nothing less and I don't see a purpose of bonding both batteries as long as the factory ground tensile wires have been replaced hopefully with the big 3 that should be done before a second battery
@@ns671fr he has them wired in parallel. So that means you still have 12 volts to charge and with most vehicals your producing around 14 volts while running. so they both will charge to 12 volts. But they appear to be different batteries. Thats the only problem. You need two batteries that are the same age and cca.
@@ns671fr check out your connections on your battery and chassis. Unless you have some serious amplifiers in your setup. One good altenator should be plenty.
Yeah battery isolator in between I'm positive that trunk battery is an AGM and need to be separated from a primary lead battery if not there will be problems. but this video is good for the concept just add the isolator between the primary and secondary battery don't forget to fuse the lines.
Great video and explanation… now don’t both batteries have to be the same brand, size, and age and if they are not an isolated need to be in the mix? I’m asking more than anything. I’m all self taught and that is the way I have grasped the concept
Provo Beast Audio Installation couldn’t you potentially lose starting power to turn the engine since no battery isolator? Also how many amps are you drawing for the added system? It’s possible to overload the oem alternator.
For sure. If we are pulling a lot of amps at the amplifier, then it would be necessary to upgrade the alternator. But for now, the factory alternator will do us. If we were to upgrade the amp, add more batteries, our alternator would need an upgrade.
This is just 2 batteries in paralel. Startup would draw power from the second battery and probably blow up the fuse. This is just like putting a bigger battery in your car. No other benefits.
@@hakont.4960 I agree Hakon. and Adrian putting a bigger battery in your car is the goal but they don't sell many that will fit so we get a second. It is parallel but the 2nd is grounded remember.
Ground loop is from poor grounds in general and low quality rca cables. Grounding an amp different from a secondary battery has nothing to do with that. Don’t believe all the “research” you have.
In a Mercedes the battery is in the trunk. Can I ground the second battery to the exact same spot that the main battery is grounded to or should I find a different ground? Thanks
I'd like to know this as well. Most answers I have seen say it should be possible when the batteries are connected positive to positive. I just want to do it the proper way though. Did you find out?
So the power cell is basically hooked up coming from the regular car battery? Wouldn’t the alternator try to charge both of these batteries? Will it kill the battery if the car is off? Thank you , Derek
Question, I'm not gonna have a booming system, but do like turning it up oldschool once in a while. What's the minimum size battery I could put in the trunk
Quick question. Let's say I already have my two amps wired to the main battery thru a Distribution block. If I add a second battery could I just run that battery to the main battery. Will it still supply extra power and work correctly.

@@ns671fr he has them wired in parallel. So that means you still have 12 volts to charge and with most vehicals your producing around 14 volts while running. so they both will charge to 12 volts. But they appear to be different batteries. Thats the only problem. You need two batteries that are the same age and cca.
@@AntDaddy1977 the alternator struggles already with a small capacitor
@@ns671fr check out your connections on your battery and chassis. Unless you have some serious amplifiers in your setup. One good altenator should be plenty.
Do you have a video explaining different kinds of battery's? Say agm under the hood and lithium in the trunk? Using a isolator?
RIGHT!!! I wish they would answer that cuz they left a lot of unanswered questions on the table
Is there any reason to use a capacitor when you're using a second battery?
Not really.
I did this when young ended up with two dead batteries... Not sure what I did wrong. Optima deep cycle in the trunk regular lead acid under the hood?
Nice simple and clean:)
Yeah battery isolator in between I'm positive that trunk battery is an AGM and need to be separated from a primary lead battery if not there will be problems. but this video is good for the concept just add the isolator between the primary and secondary battery don't forget to fuse the lines.
Bro quick question, do you know if you can run different agm batteries together? For example like a yellow top optima agm and an xs power agm?
@@goatedf6180 yes you can.
Great install guys looks really clean oawg from the front to the back of the car would have been best for future exspansion
Don't you need a higher amperage alternator to charge both batteries?
Awesome..I have the HB 2011 thanks for the video also I have the same amps GM-D8601 and GM-D8604!
Great video and explanation… now don’t both batteries have to be the same brand, size, and age and if they are not an isolated need to be in the mix? I’m asking more than anything. I’m all self taught and that is the way I have grasped the concept
See the isolator video for that information!
Loved everything about the video except for the CCA wire. EWWWW
Cool story
The color separation between ground and power too 😅 I'm sure it was corrected later, I hope.....
How do you keep the battery from sliding around easy?
Is it harmful on a stock alternator to run two batteries?
CobraFangRacing could be if your amp is a low amperage alternator .
What about a 95 amp
No its ok no problem
@vnphotovideo proaudio I know I a bit late but I thought so myself. Wouldn't he have needed to add a battery isolator as well??
Don't listen to them. You need to upgrade your alternator.
so we need 2 fuses 1 front and 1 on the back by the new battery??
Clean install. 👍
Can you please let me know what gage wire from battery to battery you use ? Thanks
Wheres the battery isolator?
Do you need a battery isolator ?
up to you, if you are using you system when the car is off, then yes.
Alex Ramirez it's always helpful depending on the size and power..and if it's mostly stock
Provo Beast Audio Installation couldn’t you potentially lose starting power to turn the engine since no battery isolator?
Also how many amps are you drawing for the added system? It’s possible to overload the oem alternator.
For sure. If we are pulling a lot of amps at the amplifier, then it would be necessary to upgrade the alternator. But for now, the factory alternator will do us. If we were to upgrade the amp, add more batteries, our alternator would need an upgrade.
TRUST ME I HAVE BEEN DOWN THAT ROAD IF YOU ADD MOR BATTERYS whats going to charge them baterys not your stock alt good work tho
What kind of rcas are those? Look slick
This is just 2 batteries in paralel. Startup would draw power from the second battery and probably blow up the fuse. This is just like putting a bigger battery in your car. No other benefits.
Two benefits are that battery closest to the amps can feet the amp spikes with less voltage loss and you can fit a bigger total capacity.
@@hakont.4960 I agree Hakon. and Adrian putting a bigger battery in your car is the goal but they don't sell many that will fit so we get a second. It is parallel but the 2nd is grounded remember.
would never pop a fuse. Bigger battery under the hood with larger capacity IS the benefit
Why would you ground amp and battery in different spots? That causes ground loop issues and unwanted interference
At least that's what I researched. I really don't know I just want to get it right the first time
Ground loop is from poor grounds in general and low quality rca cables. Grounding an amp different from a secondary battery has nothing to do with that. Don’t believe all the “research” you have.
@@ProvoBeastAudiocould I just ground the amp to the second battery
$WEET!!!
Should i run a ground from the front battery to the battery in the trunk
I JUST FARTED!!!!!!!!!!
In a Mercedes the battery is in the trunk. Can I ground the second battery to the exact same spot that the main battery is grounded to or should I find a different ground? Thanks
I'd like to know this as well. Most answers I have seen say it should be possible when the batteries are connected positive to positive. I just want to do it the proper way though. Did you find out?
So the power cell is basically hooked up coming from the regular car battery? Wouldn’t the alternator try to charge both of these batteries? Will it kill the battery if the car is off? Thank you ,
Derek
Does the 2nd battery strain more on the alternator and 1st battery? Or does it help reduce its pull on the original?
Hi, how to determine what type of battery or size?
What a great video, man this video rocks!
Why does adding a second battery connected to your main battery supply your amp with more power if
12v + 12v = 12v ?
Ok but do I absolutely need to connect the audio battery to the front battery and charging system?
Do I need to make a connection to the alternator?
How much more ware is on the alternator though 🤔
Question, I'm not gonna have a booming system, but do like turning it up oldschool once in a while. What's the minimum size battery I could put in the trunk
Will that hurt the alternator
I have a 2015 nissan versa im going to try and build an amp rack for my 2 amps i like the back vertical board you made how did you secure it
Where could the short circuit be along the 3rd fuse and the amp? If there’s nothing wrong with the amp? That’s where I’m having problems
I like this set up. Now i want to know how would i add my 15 farad capacitor in a build like this??
Quick question. Let's say I already have my two amps wired to the main battery thru a Distribution block. If I add a second battery could I just run that battery to the main battery. Will it still supply extra power and work correctly.
