What size amplifier do I need for two 12-inch subwoofers?
The size of the amplifier needed for two 12-inch subwoofers depends on the power rating of the subwoofers and the desired level of sound quality. A general rule of thumb is to choose an amplifier that can provide at least twice the RMS power rating of the subwoofers. For example, if the subwoofers are rated at 200 watts RMS each, you should choose an amplifier that can provide at least 400 watts RMS.
It’s also important to consider the impedance of the subwoofers and the amplifier. Most subwoofers are rated at 4 ohms or 2 ohms, and the amplifier should be able to handle this impedance. You should also consider the gain structure of your system and the type of music you will be playing to determine the required power output. It’s always better to have a bit of headroom in terms of power to ensure that the amplifier can handle sudden peaks in the music.
Can I install two subwoofers in the same enclosure?
It is technically possible to install two subwoofers in the same enclosure, but it’s not always the best idea. Installing two subwoofers in the same enclosure can create a number of problems, including increased air pressure, reduced low-frequency extension, and increased distortion. This is because the two subwoofers are working together to move the same air, which can create a “fighting” effect that degrades sound quality.
If you do decide to install two subwoofers in the same enclosure, make sure that the enclosure is large enough to accommodate the increased air pressure and that the subwoofers are properly aligned to minimize interaction. You should also consider using a different enclosure design, such as a dual-chamber design, to help minimize the negative effects of installing two subwoofers in the same enclosure.
Do I need to upgrade my electrical system to install two subwoofers?
Installing two subwoofers will require more power than a single subwoofer, which means you may need to upgrade your electrical system to handle the increased power demand. This includes the alternator, battery, and wiring. If your electrical system is not capable of handling the increased power demand, you may experience problems such as premature battery drain, alternator failure, and wiring overheating.
