Details

The CT Sounds CT1X8 is a single 8-inch empty car subwoofer box engineered for maximum bass response and low-frequency reproduction. The kerf-style port, universal fit, poly-filled lined internal walls, and 7.37” cutout diameter make this pre-fabricated 8” subwoofer enclosure compatible with a wide variety of subwoofer brands on the market. Its kerf-style port, typically only seen in custom enclosures, will “unhide” the missing bass in your system and have your subwoofer playing deeper and more accurately.

The CT1X8 subwoofer box was constructed using some of the most advanced joinery practices - dado joints connect the exterior left/right wood pieces to the exterior back/top/bottom wood pieces by a groove, and miter joints connect the corners of the box by cutting the wood at a 45-degree angle. These joinery practices ensure maximum surface contact and eliminate any concern for vibration. Additionally, the recessed side panels further enhance the air-tight, vibration-free construction design.

To finish the equation, the subwoofer box is wrapped in a premium-grade black carpet with a flush-mounted black terminal cup. The terminal cup features 8-gauge push-terminals labeled with red & black stickers identifying positive and negative connections. Internally, the subwoofer box comes with 12-gauge speaker wires that are pre-soldered to the terminal cup creating a true plug-n-play product offering.

The best budget prefab enclosure

I test and review subs for fun. Any of the CT boxes are great but especially the 8". I have back to backed them with the skar boxes and they are just better. I did a 137.2db with a DD608F in a sedan on 1000 watts.

Solid Enclosure!

Purchased this enclosure for a single 8 inch Tropo and it sounds amazing. Paired it with a CT Sounds 1000.d running at 4 ohms. Kept stock speakers. Sounds nice on my wife’s daily driver. May consider a small 4 channel amp on the future.

Solid 8" enclosure. No "regerts"!

CT1X8 // Single 8” Kerf Port Universal Car Subwoofer Box. I dropped a TROPO-8 // 400 Watts RMS 8 Inch Car Subwoofer in this enclosure and put it in the back drivers seat of my 2020 Dodge challenger and use it with the bass knob. This combination works great. The bass that comes out of it sounds great. Awesome well built enclosure.

Best 8" prefab box out there

I test, review, buy and sell car audio. This is the best 8" prefab on the market for for the money. The other box in the photo is the same box but 10". Makes the custom alpine Type R sound great.
