Connecting two 1200-watt subwoofers to your car's audio system will put a significant load on your battery. To ensure that your battery can provide enough power, you may need to upgrade to a higher-capacity battery or install an additional battery.
It is also important to make sure that your car's electrical system is capable of handling the increased power draw from the subwoofers and amplifier. You may need to upgrade your alternator or install a power capacitor to prevent your car's electrical system from being overloaded.
If you are not sure how to properly install and connect your subwoofers and amplifier, it is best to consult with a qualified car audio installer.
