Customer Ratings & Reviews

This custom box for the Chevy Avalanche was impossible to find at most of my local car audio shops - and ordering it was literally 4 times Best Buy's price... Saved a bundle, arrived super quick, and sounds GREAT! *Note: these boxes will not let you put the back seats down all the way in an Avalanche to extend the cargo area into the passenger area.

I got this box to add to my 2007 chevy avalanche. I added two kicker SHALLOW 10s. I got a better bass feeling inside the truck than when I had two rockford fosgate in my truck's trunk. I would recommend but don't be cheap add quality 10s subwoofers.

This box fit perfectly in my 2004 Avalanche. I put in a pair of Rockford Fosgate P1 series 10" subs (which this cabinet seemed a perfect fit for!) added in a kicker amp behind the seats and the family his happy once again with the sound of the setup! This is matched with 4 kicker 6.5" speakers to replace the original speakers. Overall the quality of the box is top notch. Had to trim away the carpet around the speaker cutouts. Wanted to make sure I got a good seal. This box rocks!!! If you don't mind giving up the space under the seats and want a great sounding box this is the way to go for the Avalanche.

Ordered the box from BestBuy.com for my first online BBY purchase ever. I've been purchasing in store for over 10 years, but I was skeptical about my online experience. I had been looking for a new sub box for my 04 WBH avalanche since the one that I bought from a shady flea-bay vendor was full of air leaks and made my truck sound EMBARRASSING! So I went and checked all over the internet and low-and-behold BBY sells a reputable name brand subwoofer box company (ATrend) for a killer (less than a hundred bucks) price. The box was shipped and at my house 4 days later - no assembly required. I mounted and drilled in my two 10" Infinity Reference subwoofers and hooked up the amp and viola. The box sits right underneath the backseats and is up-firing. No seat brackets to remove, nothing to mess with in the truck, just drop it in and GO. The box THUMPS in comparison to the trash I had in my tonka truck earlier. Really impressed, it's held up well and I'm very happy with the sound. At the price, you can't beat it - GO FOR IT

looked everywhere on the internet for the right box to put in my 04 Avalanche, come to find out best buy sells the perfect one. if your only mounting 10" subs in your avalanche this box is great, looks great fits like a glove. I installed an Alpine IXA-w404 head unit in my truck (which by the way is awesome for the price, Double den, touch screen, and optional bluetooth, navigation, and rear view camera). I got this box and 2 Alpine type S 10" subs, with the mono 500W Alpine amp Best buy also sells. Now my truck SLAMS for having just two 10" subs, Alpine Rocks. Overall i give this box a 4/5. The only problem i had was when i cranked my system near max I was hearing a rattling noise that i thought was coming from my subs, but come to find out my box was leaking a little bit, and it was the MDF board rattling together, so if you have this problem do what i did and put about 4 screws in the box to pull it together. Im sure it was just probally my box that had this issue. Either way its no reason not to buy this box, because if you have a Avalanche This is the best box you will find for your truck on the web, hands down. (unless you get the midgate box Which is about 3x the price). yea and just to remind you THIS BOX SLAMS HARD. would also recomend to only get shallow install speakers.

i bought the product after i trusted someone to find exact fit for my truck,,got box in the mail in a very timely manner. this box match my rug very pleaseing to my eyes....install speakers very..woul recommend this product to others
