I used 14 gauge speaker wire to connect my amp and PS. But it doesn't want to stay in the onboard connectors. The instructions just say to use the largest wire that can fit, not what type. Is there something better? Or do I just need a better screwdriver?

Thank you,
Duane

The wire seems fine, it's just your connection that's the problem. Solder each wire end to an inch or two length of 14 or 16 gauge SOLID copper wire (as in Romex style house wiring wire), and use the solid wire (perhaps trim as needed) on the connectors. Put electrical tape or preferrably shrink-wrap tubing over the solder joint.

I just use a tinned wire end....the solder fills the 'gaps' in the stranding & if the connector is the screw-down type, the solder deforms making a "bowl" in the wire formed by the screw tip, often 'hooking' the wire in the appliance.

Thanks guys, these are board mounted screwdown terminals. I don't have a pic handy but I think they are quite standard. They seem to have a metal spring/plate that holds the wire in place. Then the set screw pushes on that. I think that solid or tinned wire will work just fine. I have lots of romex. Is there any difference aside from flexability? (I'm sure I spelled that wrong.)

The spell-checker thinks that it's - flexibility.

One thing about solder-tinning stranded wire & screw terminals is that the solder with time will cold-flow and allow the screw to loosen.

Whit I do is strip back about 1/8inch or more of the insulation and solder-tin. Then I strip back another 1/2inch of insulation to go under the screw.
