When you are running a healthy amount of power to your subwoofers, you need a terminal system that is capable of handling that power!

Traditional terminal cups cannot handle a lot power due to the cheap and thin materials. They also require drilling a large 2 or 3" hole to then be mounted by a few screws. These screws and large mounting holes can also weaken the enclosure especially if the screws get removed and replaced (R&R) a few times

My plate system only requires drilling of two 1/4" holes for the 1/4-20 bolts. You use large washers on the inside of the enclosure, and the ABS plate on the outside with another large washer to spread the clamping force out, strengthening the enclosure instead of weakening it with a 3" hole. You can R&R it as many times as needed and it will never weaken the enclosure. 

I have built many enclosures using this plate system and i can say these handle considerably more power than any terminal cup i have used before. I rarely use any other method these days..
