Our Plug & Play Quad-Connector allows a single driver to power 4
pieces of Cool Neon wire, plug in another and you can now power 7
pieces of Cool Neon wire. Plug in 5 quad-connectors and make 16 wires
glow, plug in 50 Quad-connectors to make 160 wires glow, and so on, and
so on. They are compatible with all of our plug and play connectors: wire side
connectors, driver side connectors, extensions, and quad-connectors.

Quad connectors are super useful, you do not have to use all outputs. You don't have at solder at all. And the lead wires in the Quad-connectors are out thinnest gauge found on any plug and play connector, cutting down on bulk even more!
