This enclosure was engineered by Skar Audio specifically for the subwoofer that is loaded in it, ensuring perfect sound and compatibility.

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.

Haven’t even broken in the sub yet!! It’s great , best I’ve had yet. So far it’s amazing. Great for suvs It’s fun trying to get it into a mustang lol couldn’t do it so I put it In the back seat , big box and sub !

Without ever playing the sub the actual box stinks

I played the sub for maybe 5 minutes with the gain properly adjusted and haven’t used it since. Just letting the box sit in my car over night makes the car smell awful. The sub has not been in use, it’s not a cooked coil. It’s the actual enclosure itself that smells awful so now I’m 200$+ out and can’t do anything about this

Great loaded enclosure

Ported box is large and hasn’t been broken in yet but at this point I am seeing huge flex in my roof, windows and windshield! I have this speaker in the backseat of a Nissan Frontier and it sounds amazing! I’m only running 500rms to it and it is rated for 600rms. I can’t wait to upgrade amps and get the full potential out out of this sub!! I was running a Sundown sa12 in a ported box and this Skar 15 blows it away effortlessly! Will be loading a video soon!
