Skar Audio engineered the SDR-1X12D2 single 12-inch loaded vented subwoofer enclosure as a simplified option to add a competition-grade subwoofer system, without the guesswork involved in designing it from scratch. This loaded enclosure features one of our extremely popular SDR-12 D2 1,200 watt max power subwoofers, which arrives pre-loaded and wired up inside of a custom single 12" ported enclosure. The enclosure features a unique kerf port design, allowing for extreme levels of bass output. Furthermore, the enclosure is finished in premium grade black carpet for a sleek appearance and features the Skar Audio logo in white on the top surface of the box.


This enclosure was engineered by Skar Audio specifically for the subwoofer that is loaded in it, ensuring perfect sound and compatibility. Every subwoofer is different, and it is so critical when buying a subwoofer to ensure that the subwoofer and enclosure are an ideal match, or you will lose sound quality and output. With this loaded subwoofer enclosure model, all of those concerns are eliminated, making it easier than ever to add powerful aftermarket bass to your vehicle.


The subwoofer comes pre-wired and loaded inside of the enclosure allowing for an easy and hassle free installation. The dual 2-ohm subwoofer is wired up inside of the enclosure so that the final impedance load is configured for 1-ohm at the terminals. Peak Power: 1,200 Watts, RMS Power: 600 Watts.

Feel The Music

Prompt shipping. Arrived in a box that had wooden protection on the inside so the speaker does not get damaged during shipping. The speaker box itself is a work of art. It is durable with top class constriction. The sound quality is excellent. It hits hard and low. My music now has a visceral experience, I can feel the low bass resonating throughout the cabin. I love to put my friends in the car and watch the expression on their faces when the bass line comes in, that alone is priceless.I would highly recommend this product and continue to buy from Skar Audio.

Arrived on time

Subwoofer arrived on time and in good condition,hooked it up and it sounds amazing. I'll order from here again.

Fast shipping;awesome product

Very fast shipping. Subwoofer was everything my boyfriend wanted and more. Very very loud. Great bass. Sounds great!

Best Bang (literally) for your buck!

Ordering process was fast and seamless. Customer service was also extremely helpful in identifying the correct sub and enclosure to complete an existing setup (amp, wiring, etc). The sub arrived quickly and in great shape. Packaging was extremely well designed to protect the item. Setup and calibration took some time, but once dialed in, the sub's performance was much more than expected. Nearing the end of the recommended 20 hour break-in period where I will re-calibrate the setup and finally listen to its full potential. From what I have noticed so far, this system will perform much better than previous systems, for a far more reasonable price. Excellent product!

Good quality at great cost

I’ve waited a bit before posting a review for this product, about 6 weeks, it has held up to the hype that I was given about Skar products. I play it daily not up all the way but I have beat on the subwoofer frequently pushing it to further than I was comfortable with and it has held up. I have it paired with their RP-1500.1 D. The subwoofer is wired to 2 or 4 ohms I forget which. The shop that installed it did this to not overpower the subwoofer. The only reason I did not give 5 stars is because the SQ is not the best in my opinion but I think my purchase is worth every penny it is very loud people don’t believe that there is only one woofer in my trunk. I would recommend this product and skar audio to anyone looking for something nice that isn’t going to break the bank.
