Having a world-class sound system in our car is necessary for some of us.

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

However, installing an aftermarket system inside your car can put tremendous strain on the regular battery.

As such, you may have to replace it with a more powerful battery 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 dedicated car audio battery that came with your vehicle, then you are in desperate need of an upgrade.

When looking for the correct battery, the most important thing to watch out for is the number of cold cranking amps (CCA) and the number of watts it can produce. You must 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 consider expert input and look at what these batteries can do for you.

Car Audio Battery FAQs

1. How many CCAs 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 in determining your car audio’s power draw. 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.

2. Which is better yellow or red-top 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.

A redtop battery would probably do just fine if your car uses low-power speakers, amplifiers, and subwoofers. 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 design is 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, you need better reserve capacity, something only a yellow-top battery could offer.

3. 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 case is valid if your car is heavily modified or you want to keep the music on while the engine is off. One battery will supply your car’s basic electronics; the separate battery 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.

You only need two batteries for your car audio when you have prominent speakers installed that draw ample power from the battery. There wouldn’t be too much demand for energy on a single battery, preventing it from draining rather quickly.

4. 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 than their maintenance-free counterparts, making them a better option for deep-cycle usage.

While AGM batteries will probably cost you more, you can rest easy knowing that their electrical features are adequate for your sound system. Simply put, this is a quality battery.

5. 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.

Car Audio Battery Buyer’s Guide

1. How does a car audio battery work?

A: A car audio battery is a good investment for showing off your system and having a good audio experience, but you must understand how they work and when (and when not) to use them. Most people think that if they have an extensive, robust 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 machine on, then a second battery 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 is off, then your battery needs to be taken into account.

2. What factors do I consider before making a car audio battery purchase?

A: To ensure your car audio battery purchase is worth it, you’ll want to look at several factors.

Be mindful of how much you’re spending; you are on the right track if your stereo is cheaper than a capacitor.

It’s better to get a quality stereo system right away instead of using this alternative method. Even if capacitors give much-needed bursts of power, they consume so much space.

Next, look for a battery that won’t drain right away, even when listening to music when you are parked.

Remember that regular batteries will give you a maximum of one hour, but a good car audio battery designed to last makes a big difference.

3. What are the various car audio batteries from which I can choose my next purchase?

A: Below are the types of car audio batteries, complete with information on function and advantages.

AGM Battery

This article cites this battery many times. This car audio battery, also known as absorbed glass, utilizes up-to-date cell technology unparalleled compared to older types.

AGM batteries require no maintenance, for one, making it a primary choice, alongside its being sealed and functioning like a gel battery.

However, keep in mind that many still employ lead-acid to minimize costs.

On top of these advantages, AGM batteries hold a considerable advantage over lead-acid batteries.

Their sealed construction paves the way for more usage, sans the dangers of being spilled.

Lead-Acid Battery

Car owners who look for cheap audio battery options purchase these commonly chosen batteries also known as flooded lead-acid batteries.

These batteries work through constant topping off distilled water.

Distilled water prohibits the battery from being damaged while remaining unsealed.

However, this battery and its older technology have slowly lost their popularity from the old days because they often result in spillage.

Gel-Cell Battery

Finally, gel-cel batteries complete this list of car audio batteries. These batteries utilize water instead of electrolyte gel.

Because these batteries use electrolyte gel, its users can enjoy many benefits. For one, these also require minimal maintenance and remain sealed.

The gel’s vibration resistance also bodes well with the sealed battery, ensuring that spill does not happen.

4. How many watts is suitable for a car stereo?

A: There are a lot of factors to take into account when it comes to audio equipment. 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 make a difference when it comes to subwoofers. A 500-watt stereo with high sensitivity will end up sounding better than a 1,000 watt stereo with a lower sensitivity range.

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

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

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

6. Lastly, what other considerations do I make concerning my use of car audio batteries?

A: Consider three primary factors: maintenance, price, and size.

Having hassle-free maintenance saves you from wasting resources, effort, and time. In that case, consider prioritizing maintenance-free batteries for your next purchase.

After all, maintaining upkeep is challenging, with some batteries requiring maintenance every year. Note that mount batteries not entirely sealed might be challenging to do.

Next, price matters. Overpaying is unnecessary. Just make sure you get the power you need. Check compatibility with your car, too.

At the same time, don’t be too cheap that you end up bringing home a defective car audio battery, which might not last a long time anyway and might end up disappointing you.

Finally, consider proper sizing. How the battery fits and connects to your car is crucial. 

If you can, check with your car manufacturer and buy one that matches your vehicle perfectly.
