When you are running a healthy amount of power to your subwoofers, consider that traditional terminal cups cannot handle much 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.

This bolt system only requires drilling of two 1/4" holes for the 1/4-20 bolts. You use large washers on the inside and outside of the enclosure, spread the clamping force of the bolts out on the material, strengthening the enclosure instead of weakening it with a 3" hole.

I have built many enclosures using these bolts and i can say these handle considerably more power than any terminal cup i have used before.

This kit is only for the bolts, no terminal plates.

This kit includes:

2 1/4-20 bolts 
2 nuts for the bolts

2 wing nuts
4 large washers
4 smaller washers 
2 lock washers

4 Ring Terminals 10-12g size
4 Red and Black heat shrink for speaker wire

Optional: Speaker wire 10 Gauge Copper Red/Black wire (not the same wire seen in pictures from previous installs)

If you specify in the drop down menus to order, I will also include speaker wire for your enclosure. It will be crimped and heat shrunk on each side by me on my tool bench. Available in 5, 10ft , and 20ft lengths. If you need longer than that then please feel free to ask.

Please specify the length of the wire you need. You may also choose no speaker wire for the lowest price.

Thank you for your interest. If you have any questions please email us, or visit my facebook site for Franks Audio Motive. Or you may also find me on the group as well.
