Understanding Amplifier and Subwoofer Specifications
To bridge two subwoofers safely and effectively, you need to understand the specifications of your amplifier and subwoofer. Here are some key specifications to look out for:
- RMS Power Output: This is the continuous power output of the amplifier, measured in watts.
- Peak Power Output: This is the maximum power output of the amplifier, measured in watts.
- Impedance: This is the resistance of the subwoofer, measured in ohms.
- Sensitivity: This is the efficiency of the subwoofer, measured in decibels.
Calculating the Combined Power Output
To calculate the combined power output of the two amplifiers, you can use the following formula:
Combined Power Output = (Amplifier 1 RMS Power Output + Amplifier 2 RMS Power Output) x 2
For example, if Amplifier 1 has an RMS power output of 200 watts and Amplifier 2 has an RMS power output of 200 watts, the combined power output would be:
Combined Power Output = (200 + 200) x 2 = 800 watts
