Selecting the correct amplifier for your subwoofer setup is crucial to achieve the best sound quality and performance. If you have two 800-watt subs, you’ll want an amplifier that can adequately power them without distortion or damage. In this article, we’ll guide you through the process of determining the right size amplifier for your subwoofers.
Understanding Subwoofer Power Handling
Before diving into amplifier selection, it’s essential to understand your subwoofers’ power handling capabilities:
- RMS Power: The RMS (Root Mean Square) power rating of a subwoofer indicates the continuous power it can handle without overheating or causing damage. This is the most critical specification to consider when matching an amplifier.
- Peak Power: The peak power rating represents the maximum power a subwoofer can handle in short bursts. While it’s essential not to exceed this value, it’s the RMS rating that you should primarily focus on.
- Impedance: Subwoofers have impedance ratings, typically measured in ohms (Ω). Common ratings include 2 ohms, 4 ohms, and 8 ohms. Make sure your amplifier is compatible with the impedance of your subwoofers.
Selecting the Right Amplifier
When choosing an amplifier for two 800-watt RMS subwoofers, follow these steps:
- Determine the Total RMS Power: To calculate the total RMS power handling of your subs, simply add the RMS power rating of each subwoofer together. In this case, it would be 800 watts + 800 watts, resulting in a total of 1600 watts RMS.
- Choose an Amplifier with Sufficient RMS Power: Your amplifier should provide enough RMS power to match or slightly exceed the total RMS power handling of your subwoofers. In this scenario, you should look for an amplifier that can deliver at least 1600 watts RMS at the impedance of your subwoofers.
- Consider Impedance Matching: Ensure that the amplifier’s impedance rating matches the impedance of your subwoofers. If your subs are 4 ohms each, a 4-ohm stable amplifier is ideal.
- Account for Efficiency: Keep in mind that amplifier efficiency can vary. Some amplifiers may require more input power to achieve their rated output. To be safe, select an amplifier with slightly more power than your calculated RMS requirement.
- Amplifier Features: Consider the features you need, such as adjustable crossovers, bass boost, and protection circuits. These features can help you fine-tune your system and protect your subwoofers.
- Brands and Models: Research reputable amplifier brands and models known for quality and reliability. User reviews and professional recommendations can provide valuable insights.
Conclusion
Selecting the right amplifier for two 800-watt RMS subwoofers involves understanding the power handling capabilities of your subs and matching them with an amplifier that can deliver sufficient, clean power. Remember that it’s better to slightly overmatch the amplifier’s power rating to ensure headroom and prevent distortion. Carefully review the specifications and features of amplifiers, and consider seeking expert advice if you have any doubts about your selection. With the proper amplifier, you can enjoy deep, powerful bass that complements your car audio system effectively.
