Customer Reviews
My F-150 sounds amazing!
I got the custom fit sub box for my Ford F-150 and it's incredible! The bass is so tight and clear now. I can't believe the difference it made. My truck sounds like a concert hall! I'm telling everyone about Groundshaker. I will definitely be buying from them again!
Consistent quality, happy repeat customer
This was my third purchase from Groundshaker, this time a shallow mount enclosure. Just like my previous orders, the quality was consistent. The birch wood enclosure was well-made and sturdy, just as I've come to expect. Shipping was prompt, arriving in about 5 days to Denver, which is typical for them. They've always been reliable, and their products hold up over time. It's why I keep coming back when I need a new box.
Good box, fast shipping
I ordered a 10 inch speaker box. It arrived quickly. The quality was good for the price. Fit my sub perfectly. No issues.
Great value on a quality box
As a first-time buyer, I was looking for the best deal. I signed up for the newsletter and got 10% off my first order, which was a nice bonus. I bought an underseat enclosure for my Tacoma. The price was competitive even before the discount, and with it, it felt like a real steal. Shipping was free, which also saved me a good chunk of money. The enclosure itself seems well-built and fits perfectly. For the money spent, I feel like I got excellent value. Definitely a worthwhile purchase.
Decent enclosure, minor issue
I bought a ported 10 inch enclosure. The build quality was solid for the price, and it certainly improved my car's audio. Shipping took 7 days to get to me, which was a bit longer than I hoped but still within reason. I also noticed a very small scuff on one corner of the carpet, nothing major but it was there. Customer service was responsive when I inquired about tracking. Overall, it's a good product for the price point, but they could probably improve their packaging slightly to avoid any small cosmetic issues.

Anyone know if they do free shipping often? Or like, is there a code for that floating around?
Do their enclosures come with the terminal cups pre-installed, or do I need to buy those separately?
Hey guys, thinking about grabbing a custom box for my F-150. How long does shipping usually take, especially if I'm in like, Florida?
What's the deal with returns? Say I order a box and it doesn't quite fit, can I send it back easily?
Hey, does Groundshaker offer any kind of discount for military members? My brother is looking for a new setup.
planning to buy a box during tax refund season. Do they usually run a sale then?
Can I use more than one coupon code at checkout? Like, if I have a newsletter signup code and a holiday one?
Thinking of getting a box for my Tacoma. Anyone compare these to like, Fox Box or Subthump? Wondering about quality differences.
