Will this work with banana plugs?
[ Mally  Jun 05, 2019 ]
1 answer
Yes it should, I didn't use banana plugs, I just solder the tips
[ Nelson  Jun 07, 2019 ]
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...
