If you’ve made the leap to upgrade your car audio system with two 600-watt subwoofers, you might be wondering: what size amp do I need to optimize their performance? This question is crucial to achieving that earth-shattering bass you crave, and the right amplifier will ensure you get the best sound quality without damaging your equipment. In this comprehensive guide, we’ll explore the essential factors that determine the size of the amplifier you need, the types of amplifiers available, and how to properly match your subs with the optimal amp.
Understanding Subwoofer Specifications
Before diving into amp selection, it’s essential to grasp your subwoofers’ technical specifications. Each 600-watt subwoofer can handle a maximum of 600 watts RMS (Root Mean Square), which denotes continuous power. However, understanding how much power your amplifier should deliver requires some further investigation.
RMS vs. Peak Power Ratings
It’s important to distinguish between RMS power and peak power ratings:
- RMS Power: This represents the continuous power a subwoofer can handle over time without damage. For two 600-watt subs, their total RMS rating is 1200 watts.
- Peak Power: This indicates the maximum power the subwoofer can take for short bursts, which is often significantly higher than RMS. For instance, a 600-watt sub may have a peak rating of 1200 watts or more.
For high-performance audio, always focus on the RMS number, as this rating tells you how much consistent power your amp needs to provide without risk of overload.
Calculating the Required Amplifier Power
To securely power your two 600-watt subwoofers, you should look for an amplifier capable of delivering at least the same amount of RMS power as your subs when combined. In this case, you need an amplifier with:
RMS Output of at least 1200 watts
However, it’s a common practice to use an amplifier with slightly more power than the subwoofers can handle. This allows for some headroom, ensuring the amp doesn’t work at full capacity all the time, which can lead to distortion or damage.
Choosing the Right Amplifier Type
When it comes to amplifiers, you’ll typically find two types to choose from:
- Monoblock Amplifiers: These are designed to power a single subwoofer but can also be used for multiple subs, depending on their output power. A monoblock amp is ideal for subwoofers, offering high power in a compact design.
- Multi-Channel Amplifiers: These can power multiple channels of speakers and subs and are beneficial for comprehensive car audio systems. However, you should ensure that the amp’s output meets the needs of your subs.
For two 600-watt subs, a monoblock amplifier is typically recommended for dedicated power delivery and easier setup.
Matching Impedance
Another crucial aspect of selecting an amplifier involves matching the impedance of your subwoofers with that of the amp. The common subwoofer impedance values are:
- 2 Ohms
- 4 Ohms
Subwoofers can come in various configurations, and their impedance can significantly affect how much power your amplifier will deliver. For instance, a monoblock amplifier delivering 1200 watts at 1 ohm can be significantly beneficial when paired with a suitable sub setup.
Wiring Configurations
The way you wire your subs can affect your amplifier options. Here are some configurations you may encounter:
Series Wiring
This setup will increase impedance, leading to lower power output. For two 4-ohm subs wired in series, the total impedance would be 8 ohms. While this is safer for your amplifier, it reduces overall output.
Parallel Wiring
Opposite to series wiring, connecting subs in parallel will halve the impedance, increasing your overall output. For two 4-ohm subs wired in parallel, you’ll achieve a total impedance of 2 ohms, allowing for maximum power from an amplifier compatible with lower impedances.
Importance of Amp Quality
Not all amplifiers are created equal, with differences in design affecting sound output quality and durability. When selecting an amplifier for your subwoofers, consider:
Brand Reputation and Reviews
Always research brands with a proven track record in the car audio industry. Look for amplifiers that have consistent positive reviews for sound quality, durability, and effective customer service.

Built-in Crossovers
Crossovers are filters that send the appropriate frequencies to your subs, preventing them from straying into unacceptable ranges, thus improving sound clarity. Some amplifiers come with built-in adjustable crossovers, which allow you to tailor the output to your personal preference.
Signal-to-Noise Ratio
This measurement indicates how much background noise is present in the audio signal. A higher signal-to-noise ratio means clearer sound, improving your overall listening experience.
Remote Bass Control
Some amplifiers come with a remote control that allows you to adjust the bass levels while driving. This feature can be incredibly handy, letting you adapt to various music styles or environments.
Final Recommendations
Choosing the right amplifier to power your two 600-watt subwoofers requires careful consideration of several factors, from RMS power output to impedance matching and additional features. Here are a few recommendations worth exploring for optimal performance:
| Amplifier Model | RMS Power Output | Impedance |

Make your choice wisely, and you’ll find yourself enjoying an auditory experience that shakes the foundations of your ride and satisfies your craving for bass!
What size amplifier do I need for two 600 watt subs?
To power two 600 watt subwoofers efficiently, you should look for an amplifier that can deliver a combined power output of at least 1200 watts RMS. It’s crucial to ensure that the amp you choose can handle the impedance of the subs you are using, typically either 2 ohms or 4 ohms, depending on how they are wired. Most manufacturers provide guidelines about the recommended amp size for optimal performance.
Choosing an amplifier that matches or slightly exceeds the total RMS rating of your subs ensures that you won’t underpower them, which can lead to distortion and damage, or overpower them, which can cause the subs to blow. Make sure also to consider the amplifier’s efficiency and how well it converts the power from the battery or power source into audio output, as this can significantly impact performance.
Should I go for a mono or multi-channel amplifier?
For powering subwoofers, a mono amplifier is usually the best choice. Mono amplifiers are designed specifically to drive subwoofers and can deliver the high power and low frequency needed for deep bass. They provide a simple yet effective solution for achieving optimal performance with your subs.
In contrast, multi-channel amplifiers can be more complex as they are designed to power multiple speakers or channels. While they can work with subs, mono amplifiers are typically more efficient and can concentrate power on the specific demands of your bass music without dividing the output across channels.
What impedance should I look for in an amplifier for my subs?
The impedance of your amplifier should match the impedance of your subwoofers in their final configuration. If you have two 4-ohm subwoofers wired in parallel, for instance, your amplifier should be rated to handle a 2-ohm load. On the other hand, if they are wired in series, your total impedance will be 8 ohms, so you would want an amp rated for that load.
Selecting an amplifier with a matching impedance load is crucial for maximizing your system’s performance. Using an amplifier that can’t handle the impedance can lead to overheating and potential damage, while choosing one that matches ensures efficient power transfer and clearer sound quality.
How do I determine the RMS power rating of an amplifier?
The RMS power rating of an amplifier represents the continuous power it can deliver to a speaker without distortion or clipping. To determine this rating, check the amplifier’s specifications provided by the manufacturer, which often detail the RMS output for various impedance loads.
When choosing your amplifier, ensure that its RMS power rating aligns appropriately with your subwoofers’ specifications. As a rule of thumb, pick an amp with a RMS rating that is equal to or about 75% to 100% of the total RMS rating of your subs for optimal performance without the risk of damage.
Can I use a car amp for home subwoofers?
While it is possible to use a car amplifier for home subwoofers, it requires some considerations regarding power supply and impedance matching. Car amplifiers are designed to operate on a 12-volt electrical system, which may necessitate a power supply conversion for home use.
