I'm hoping the SKAR SDR-D8 will fit. The box came in 2 days after I ordered it. I was pleased at how fast. The box itself looks to be a good buy and is sturdy. It will be put to use soon. Toro R6 to push them 😈

Speaker didn't fit had to trim the holes then the screws wouldn't tighten just kept turning you get what you pay for i guess

Bought for 2011 crew cab and fit under seats without seat lift and box made it to my house day after purchase, but it was a little beat up due to no extra packaging in the cardboard not even plastic. I can’t complain to much more tho just wanted a box to put svr 8s in and they will do the job so for the price it’s worth it

First and foremost it looks nice. That said and considering the price you get what you pay for everything about the construction of this box is off. The mdf is too thin for 4 8" subs and the port isn't correct for this size of air volume, other than that the box fits nicely in my 2015 chevy highcountry. But you might want to consider upgrading if your on a budget. I only bought this because it looked cool lol but your best bet is side port and two 8" subwoofers. For testing I put them in my jeep wrangler rubicon and they do pound hard but just use some gasket or silicone around the subs. Good luck with yours!
