Can I wire RGB LED flex ribbon with cat5?

I made 4 custom light boxes using rgb led flex ribbon, can I power and wire these using cat5 cable or is that too thin for 6 amp 12v power supply these things are going to?

the longest run from one box to the powersupply will be 20 feet

any ideas anyone? what Im stuck on is can I pass enough electricity through 2 of the cat5 wires to power these things?

I don't know about this. I tried using phone cable (Cat3?) but it seems like the wires are too thin. Connected that way, I get no light at all. Connected directly, I'm getting some flickering like there's a weak connection. But I'm using a 12v 2a wall brick, so maybe not enough amps for the LED?

I work for and we have used cat5 to send 12v power down many times before and over 20 meters without any problems.
Use heavy audio-connectors and some mains cable rated for 10A (or 15A if you can't get 10).
6A is a lot of "juice" - you need a lot more metal in the cable.

I've seen this done too. Many contractors are doing it this way. You would be best off trying to use 24V LED strip as it uses less current than 12V. I've seen it done with 20 metres of 24V RGB total 144W or 6 amps and it worked fine.

do you really have 6Amps worth of lights in each box? that would be 32' of RGB strip light per box and that would only be on the black wire (+) the other R, G, B, wires would only have 2amps on them

Ok these will be RGB Light boxes not permanent I wanted to use telephone wiring jacks to do quick connects and disconnects of the boxes off the wall if I should ever need to.......... guess I cant use telephone wire then either....... basically it has 3 wires for color and one wire for electric.... which go back to a controller box which is powered by a 6 am power supply....
