The enclosure features a unique kerf port design, allowing for extreme levels of bass output.

First off, who ships from St. Petersburg, Florida to Chandler, AZ; overnight, for free??? Let me answer that for you, SKAR!
I placed my order at approximately 6:30pm on a Sunday. When I arrived home from work at approximately 6pm the next day Monday. The box was at my door step. I could not believe it!
I also took full advantage of their Black Friday pricing. I don’t believe I could have found a better deal for what I received anywhere else.

I purchased the SDR-1X12D2, TX69, & TX65.
In laymans terms, a 12” Sub in a ported box. 2-6x9’s and 2-6.5’s from SKAR. I mated it all with the Rockford Fosgate Punch P1000X5 1000 Watt, 5-Channel Amplifier. I also went with the Alpine ILX-W650 Digital Multimedia, 7-Inch Screen Mechless Bluetooth Car Receiver.

To say this system sounds good would be an understatement. It all went in a 2006 Chevrolet Monte Carlo Super Sport.

I’ve been putting systems together since 1995. This is my first ported subwoofer box, and it sounds amazing. Everything from SKAR is doing what it should. Highs are high. The Bass is Low. The mids tie them together.

I have about a 35 minute commute to work 5 days a week. 95% of the drive is on the freeway. I pretty much ride with the volume on max all of the time. With the widows down, and the roof open at highway speeds. The music is still loud and clear.

I’m am very glad I did my research and strayed away from all Rockford Fosgate. I’m still a Fosgate fan. However, these SKAR speakers should not be doubted. They are the truth!

Amazing Subwoofer

I would buy this subwoofer again and again and again. More than enough power with the ported box. Installed in my Ford Flex.


I paired this with the Skar RP-800.1D amplifier and I am thoroughly impressed. The scary part is I only just got it installed and have not set the bass knob past halfway. The bass is sufficiently heavy but not overbearing, a great fit for my stock head unit. This setup was installed in my 2017 Mustang and I start laughing out of joy every time the bass hits, I think the price is great as well. Don’t hesitate on buying this setup, it might go out of stock because I can definitely see Skar becoming the biggest name in car audio. Awesome stuff Skar audio.

12 inch sub and amp package

I have got to tell you I am so happy with my purchase. This set up hits so hard and looks and feels amazing. I have always wanted skar just from hearing them and I finally got one. I have a Dodge Durango and this thing sounds amazing. Waaaaaay worth the money and I look forward to getting a bigger amp and a evl 12 in the future. I highly recommend this package. And for the price you can not go wrong. They take the guess work out and send you what you need to be fully satisfied. Thank you skar. My Xmas just got better


This is bs it started messing(I have a 1200w ajar amp hooked up and wired professionally) up and I pull it from the housing to check and find pieces of metal left inside with the speaker that coulda caused it to mess up its parts of a razor blade and a smaller piece in the coils this is horrible business
