What size mm is the nut on the back side? None of my sockets fit and I don't want to buy a new set or wrong sizes. Also prefer socket vs crescent wrench as the space and wires connected would make a socket easier. Thanks

In all honesty- I don't know. My ex bought them with my personal information and I had to file identity theft. Not to tell you the situation but just don't want you wondering why I never replied back! Hope you find the answers you're looking for!

Will this work with banana plugs?
[ Mally  Jun 05, 2019 ]

Yes it should, I didn't use banana plugs, I just solder the tips

Do you sell one that has 4 connections?
[ Thomas  Jun 20, 2015 ]
1 answer
Why do you need one with 4 connections? I can't see a need to run two amps to a single speaker enclosure, and you can wire the inside of the box in either parallel or series, for a dual voice coil, or a single. If it's something you really need to do, then install two of them...
