What we sell?Gravity Audio G12BD1 Single 12" 1000W Loaded Warzone Competition Series Vented Subwoofer Enclosure Built in Amplifier 4 Ohm with High Premium Wood - 12 Inches - Universal Fit Benefits of Subwoofer Boxes. Optimal subwoofer performance. A subwoofer typically produces sound from the back and front. Without an enclosure, the sound from the back of the speaker would cancel out the frequencies from the front of the speaker. A subwoofer enclosure contains the frequencies at the back of the speaker to create uniformity in sound. Prevent Overheating. Most subwoofer boxes leave enough room around the speaker for air to flow in and out freely. That helps in cooling the subwoofer speakers to prevent overheating and damage to critical components, especially when you are playing loud music. Good aesthetics. Most manufacturers design subwoofers boxes with carpeted exteriors that match most vehicle interiors. The enclosed subwoofers make your car look classy, especially when placed in your trunk. Ported or vented boxes reinforce low bass response. They give a more forceful bass than sealed boxes, regardless of the amplifier wattage. Ported boxes also improve airflow to the subwoofers to prevent overheating especially when playing music for longer periods of time. They are suitable for playing heavy metal and similar types of music when driving.

Product Highlights: A subwoofer is a speaker that's designed to reproduce bass. They cover the lower end range of frequencies. A sub can add a level of power and sound to your music that other speakers cant reproduce. It's one of the necessities to a well-rounded car stereo. Add one of the best car subwoofers to your stereo and you'll wonder how you listened to music without one. Car subwoofers can make or break a new car audio system. We remember the first time we drove away from getting our subwoofer installed, and we really haven’t been able to go back to being without at least one in our car. How to choose the best car subwooferMoney – There are some subs that are budget-friendly and priced at under $200 and less, while others can go a bit higher but provide some more quality and power. How much you have saved up will help determine which direction to go. Are you building your own car sound system? Plan accordingly. Watts of power? Well, we’ll be honest — the bigger isn’t always better. If you’re getting a subwoofer for your car, you’re already getting a lot of power and volume, so there definitely is threshold when it comes to “too much”. We’d recommend staying with 8". If you have the space, I would recommend to get a 8" to have that all around bass. Do you need it enclosed? When it comes to the best car subwoofers, some come without an enclosure (box to hold them in), while others are just the bare sub (we like this sealed or enclosed subs article here). The advantage of buying them bare is being able to make or buy your own enclosure to fit in (especially if you’re looking at adding two subs to your system, you can find an enclosure that fits two very nicely next to each other). We found some that are already enclosed for you while others that are the bare version to give you options. This is huge for a small budget. This is one of the best car subwoofers in the budget-friendly realm and it has great performance. This is a new model by and the power seems to be improved from the previous generation. There is a cone woofer feature that offers accurate bass sound and when you carry the subwoofer, you will notice that it is lightweight. Even better, it offers great quality sound and high sensitivity that is definitely an awesome addition to any car.
