For some of us, having a world-class sound system in our car is a necessity.

Considering that we spend so much time in our vehicles, it makes sense that we would want an immersive listening experience.

However, if you install an aftermarket system inside your car, this can put tremendous strain on the battery.

As such, you may have to replace it to ensure that your sound system can operate at peak efficiency.

Since car audio is hugely important to me, I want to show you some of the best batteries out there for your aftermarket system. If you’re still using the battery that came with your vehicle, then you are in desperate need of an upgrade.

When looking for the right battery, the most important thing to watch out for is the number of cold cranking amps (CCA) and amount of watts it can produce. It’s essential that you find a unit that matches CCA to your speakers RMS wattage to ensure proper syncing of the two.

So, with that in mind, let’s take a look at what these batteries can do for you.

Top 5 Best Car Audio Battery For The Money 2019 Reviews

Starting us off is this auxiliary battery from XS Power. Technically speaking, this model is designed to supplement the power provided from your current starter unit, but it can be repurposed as a replacement for your original battery.


  • CCA: 1000
  • Reserve Capacity: 135 minutes
  • Watts: 2500-3500
  • Warranty: Three years
  • Size: Group 34

However, if you plan on doing that, you will have to buy battery terminals to make it work. Also, the starting power is not going to be as much, since this is considered a “deep cycle” model.


Nonetheless, this battery is perfect for car audio. It works well for systems that use up to 3500 watts, as it can produce up to 3,300 amps. So, if you are planning on going all out with your sound system, this battery will be able to handle it all.

That being said, because it’s designed for such a high output, you shouldn’t get it if you are just doing a minor upgrade. The size and cost of this battery are relatively steep when you compare it to a standard model, so I wouldn’t suggest going this route unless you need this much power.

Also, keep in mind that when doing a full upgrade of your vehicle’s sound system, you have to do the “Big 3” changes. That includes replacing the alternator and upgrading the connectors as well as the capacitors. If you don’t do all of this, then your system will overload your car and cause all kinds of problems.

Overall, this is a durable, high-performance battery that uses absorbed glass mat technology to provide ample electricity to any sound system. It is reliable and built to take on all comers.



Next, I have another high-performance battery that can work well as an auxiliary or primary power unit for your car.


  • CCA: 1700
  • Reserve Capacity: 110 minutes
  • Watts: 2400
  • Warranty: Two years
  • Size: Group 31

As with the XS Power unit above, you will need to purchase terminals if you want to use this as a replacement for your current starter battery.


Nonetheless, this model will provide more than enough electricity for most high-end sound systems.

What I like about this battery is that it has a super low ESR rating, which makes it far more efficient.

With deep cycle models, it’s imperative that you have as little resistance as possible so that they can recover from discharging much faster.

The other thing that I appreciate about this unit is that it is sealed.

This means that you can mount it anywhere and it won’t leak, and it will last much longer than traditional models.

Also, since it uses absorbed glass mat technology, it’s much more efficient than a regular lead-plate battery.

Finally, it is insulated against both heat and vibration.

This is another reason that the battery works well in any mounted position, as you don’t have to worry about environmental damage.

This also makes it an ideal choice for off-road vehicles since it can take a beating without stopping.



As far as battery brands go, none are quite as well respected as Optima. The reason that these models are so incredible is the design and shape of their cells.


  • CCA: 750
  • Reserve Capacity: 120 minutes
  • Watts: 1400
  • Warranty: 36 months
  • Sizes: Group 34

While they are not quite as reliable as absorbed glass mat, they are almost as good, making them far superior to traditional lead plates.

That being said, these models are not 100% sealed, so be careful about avoiding leaks.


What I like about this battery is that it works well as a starter or a deep cycle model.

While it’s not as powerful as a unit that’s designated as a “starter,” it can work on most vehicles without any problems, and you don’t need to buy any extra terminals.

I also like that this model recharges fast and can be depleted over and over again without damaging the internal components.

Additionally, it’s super well insulated against heat and vibration, making it ideal for most off-road vehicles.

Finally, because of the way it’s designed, this battery is perfect for cold weather starts as well, which is better than most of the other batteries on this list.



I’ve already shown you one of the higher end models from Kinetik, but if you aren’t planning on getting a massive sound system for your vehicle, then you will probably want something like this instead.


  • CCA: 600
  • Reserve Capacity: n/a
  • Watts: 600
  • Warranty: One Year
  • Sizes: Group 31

Rather than providing up to 2400 watts for your speakers and radio, this battery can only operate up to 600 watts.


This also means that you won’t necessarily have to go with a “Big Three” upgrade to ensure that your car can handle the extra power.

Overall, the performance of this battery is just as good as the other Kinetic unit, but it provides less energy. It’s entirely sealed to prevent leaks, it has an ultra-low ESR rating, and it is expertly insulated against heat and vibration.

You can mount this battery practically anywhere without any problems. I also like that it uses absorbed glass mat technology since that is much more reliable and durable than lead plates.

Finally, this battery is much less expensive and lighter than the other units we’ve seen. So, if you just want a modest upgrade to your sound system, or you want a simple auxiliary battery to help share the load, this is a perfect addition to your vehicle.



The Odyssey PC680 is an excellent battery for the budget-conscious consumer who is still looking for something with a little bit of a wallop. This battery might not deliver all the power you expect from the higher-end models on the market, but what it lacks there it more than makes up for in other ways.


  • CCA: 170
  • Reserve Capacity: 24 minutes
  • Watts: Up to 1380
  • Warranty: Limited 2 year
  • Size: 7.15 x 3 x 6.65 inches


The Odyssey PC680 is designed to give you long-lasting satisfaction. Boasting a life cycle that can stretch up to 70% longer than most other deep-cycle batteries, you can expect it to be around for a while. 

This battery also recharges faster than most other comparable models. You can expect it to be fully recharged within just a couple of hours.

In addition, this battery is easy to mount, and can be fit into a variety of places. Its non-spillable, rugged construction can handle just about anything you throw at it – in any condition. At 1380 Watts it can also run some good systems out there, but it might struggle for those that really need a lot of power. In that case, the Odyssey PC680 is perfect for adding just a little bit of boost to put your existing system over the edge.



The Mighty Max Viper VP-600, at first glance, looks like a strange addition to this list. It does not boast specs anywhere near the other options, honestly. However, this battery is actually perfect for many audio needs, depending on what you’re looking for.


  • CCA: N/A
  • Reserve Capacity: N/A
  • Watts: 600
  • Warranty: 1 year
  • Size: 7.20 in x 2.99 in x 6.50 in


Let’s be clear: this battery is not meant to replace your vehicle’s existing battery, whether that’s a factory battery or something you put in later. Instead, this battery is perfect for situations where you are looking for a way to boost the power feeding into your amp.

Because it is designed to be leak free and mountable anywhere, the Mighty Max can literally be put where you need it to go, in any space that will hold it. This makes it the perfect way to customize your system and get it looking and running just how you want it.

For a battery with this low of a price, the 600 Watts of power it delivers are certainly worth having, and you can count on the Mighty Max to power all but the most energy-greedy of amps on the market today.

It’s strong and durable, and can stay at maximum performance even under harsh road or weather conditions. Even more, it’s built to be worry- and maintenance-free. Once you get is set up how you want it, you can practically forget it’s even there; no need to worry about leaks or spills.




How many CCA do I need for car audio?

A: CCA is a standard rating that refers to the battery’s ability to run despite cold temperatures. To help you decide on this, a handy rule to follow is to first determine the power draw of your car audio. Then, find a battery with a CCA rating of at least triple this amount.

It may sound like an exaggeration to some. However, keep in mind that it’s much better to have an excess reservoir of battery power than to have a high-demanding amp system that your battery can’t accommodate.

Which is better yellow or redtop battery?

A: Whenever you’re looking for a battery for your car’s audio, you may find that the most common options you have are yellow-top and redtop. Often, you use a redtop battery for a wide variety of car electronics applications, ranging from ignition to lighting. 

If your car uses low-power speakers, amplifiers, and subwoofers, a redtop battery would probably do just fine. However, if your car’s electronics are heavily modified, which means you’ve installed numerous lights and speakers, a yellow-top battery would be better.

The reason behind this is that yellow-top batteries are designed for deep-cycle consumption. While a redtop battery would probably give you more cranking amps, you wouldn’t need this in your car audio. Instead, what you need is better reserve capacity, something only a yellow-top battery could offer.

Do I need two batteries for car audio?

A: If you’re asking whether or not you should have a separate battery for your car audio, then the answer is yes. This is especially true if your car is heavily modified or you want to keep the music on while the engine is off. One battery will supply power to your car’s basic electronics; the other will power your speakers and amplifier.

On the other hand, if your question is whether or not car audio needs two batteries, not including the battery of the car’s electronics, then that depends on your car’s audio system.

The only reason you need two batteries for your car audio is when you have large speakers installed that draw ample power from the battery. This means that there wouldn’t be too much demand for power on a single battery, preventing it from draining rather quickly.

Are AGM batteries good for car audio?

A: If you have looked around for a car audio battery, you probably came across AGM batteries. They are generally more expensive than maintenance-free batteries, but they would be better for your car audio.

AGM batteries are capable of withstanding multiple drains. What’s more, you can recharge them quicker as compared to their maintenance-free counterparts. This makes them a better option for deep-cycle usage.

While AGM batteries will probably cost you more, you can rest easy knowing that their power capabilities are adequate for your sound system.

Do subwoofers drain car batteries?

A: Subwoofers operate at the lowest frequency range and often demand a lot of power from a battery. Because of this, your car battery will eventually drain, no matter what type of subwoofer you install.

That’s why if you have multiple subwoofers inside your vehicle, it’s always a good measure to install a separate battery to power your car audio.

Buyer’s Guide

How does a car audio battery work?

A car audio battery is a good investment for showing off your system, but you have to understand how they work, and when (and when not) to use them. Most people think that if they have a large, powerful system they automatically need a bigger battery, but the real question is whether you will be running it with your engine on, or off. 

If you are running it with the engine on, then a second battery really doesn’t do you much good – all it does is put an extra load on the alternator.

If, however, you want to crank your sound while the engine if off, then your battery needs to be taken into account. 

How many watts is good for a car stereo?

This is actually a very difficult question to answer, as there are a lot of factors to take into account. Generally speaking, though, most high-end car stereos run between 200 and 500 Watts. However, there are a lot of factors that can affect your sound. Impedance, for example, can really make the difference when it comes to subwoofers, and a 500-watt stereo with high sensitivity is going to end up sounding better than a 1,000 watt stereo with a lower sensitivity range.

All in all, it really depends on the entire system that you put together.

Where should I put a second battery for a car stereo?

If you are using a pair of batteries, make sure that they are matched – that is, same manufacturer, same specifications. Typically, one battery will go right where the original battery went, and the other will be in the trunk.
