These boxes are great
Received the box really quick I installed over the weekend sounds great and looks really nice in my truck
So I haven't had the chance to install everything yet but based on my 1st impressions, the box looks fantastic. My only main complaint is that the spring terminals are kinda cheap. The inside part that connects to the subs is the flimsy tabs style while the outside that connects to the amp is the spring terminals. I would've much rather had front and back both be spring terminals, or both be the nut and bolt style. Might end up replacing them with better ones before installing
The inside connection can be made in several ways. The speaker wire can be soldered to the metal tab or you can crimp a ring terminal to your speaker wire and use the nut to bolt it to the back side. I prefer the ring terminal method. Either way is capable of flowing more power than any sub that fits in this sub box can handle.
