Face it, an overstuffed cabin makes even the swiftest road trip feel as slow as molasses. Even if we had supersonic cars to whiz us coast-to-coast in hours instead of days, we'd still need to stow our super-sized load of stuff. Well, with the Thule Sonic Cargo Box riding up top, your gear stays out of the way and you look like you're traveling at the speed of sound—even if you're cruising the speed limit.
Featuring an Aeronose and an angle-cut back, your Thule Sonic Rooftop Cargo Box slips right through the wind—silent and sleek. What's more, the AcuTight Mounting system installs to most factory or aftermarket racks and makes a distinct “click" once secured. And, thanks to the dual side opening box design, packing and unpacking is a breeze from either side of your ride. Plus, the oversize SecureLock keeps your valuables safe and is easy to use even with gloves.
If you need a lot of room or just a little extra space, the Thule Sonic Roof Cargo Box has you covered. Available in 4 sizes ranging from petite to the gargantuan, there's one for every road trip. And, it's available in your choice of black of silver to accent your topside style. Best yet, Thule builds it from advanced ABS, coats it with a high-gloss automotive finish and backs it with a Lifetime Warranty.

First - I Love AutoAnything. I always get incredible customer service reps, and I always get a good product, delivered quickly. They have my business for life. Second - Received the Thule Sonic right before a long road trip from NC to IL and back. Couldn't have been happier to have it. Although it feels somewhat flimsy when it is open, it is very sturdy when shut. The grips that hold the box down have built-in tension break, so you don't have to wonder if it's too loose/tight. Once secured it absolutely will not move or slide. We purchased the Medium, and had plenty of space inside. My only concern is that the closing mechanisms don't always line up exactly (probably due to cargo, etc), so a few times I had to work at getting the latch points to line up correctly in order for the lock to engage. If the lock doesn't engage you can't get your key out! Also - in an effort to protect the case during shipping, Thule places 'stick-on' foam padding all around the edges of the cargo box, which is a good thing for the most part. Problem is that if your shipper stores the box on its side, those foam pad will put pressure on the case. Outcome - the left side of our case (around the lock) is slightly bent inward, leaving a slight openeing between the lid at the base. We did get a little water in the case during a hard rain...I'm assuming because of this gap. This wasn't a product defect, rather an outcome of bad shipping probably. That said - once secured to your roof, you'll barely be able to tell it's there, as it has almost no noticeable noise while driving. We had to take our garage door opener off the visor in fear that we'd forget it was up there! Again - phenomenal product, and phenomenal company.

After careful research of rooftop cargo boxes, manufactured by others, I have decided on Thule box, based on previous experience with similar boxes. Smooth and efficient delivery by motor freight carrier with no shipping charges. Good looking box, easy to mount on existing roof top cross bars and easy access from both sides. I am happy with this purchase.

I looked at every available cargo box on the market I think. I watched YouTube videos, read online reviews from professionals and users. I'm sure I over did it. I debated as to whether or not the Sonic box was worth the extra money to get its dual-side opening feature or slick surface. What I can say is that this box looks like a premium accessory, not a bargain basement "appliance" to put stuff in. I found I really did appreciate being able to access cargo from both sides as well.

We have a 2011 Town and Country, and use it for sleeping. We needed a little more room for our food and for our ice chest and portable stove.

I have only used it once, but thus far I am satisfied. Managed to fit sleeping bags and pads for three, two camping chairs, plus a couple of personal bags and some small odds and ends. Sturdy construction (once closed and locked). No major effect on gas mileage. Relatively quiet (notable noise, but can still have a normal conversation in side). Note: If you're a jump right in without the instructions kind of person, remember that you can only open one side at a time. I recommend this box!
