    Re: Amplifier wire termination suggestions.

    I just take extra care with bare wire and crank down on it. If there's too much exposed I trim a little off and try again. With speaker wire I double it up at the end so the set screw will have twice as much to sink its teeth into. Seems to be way more secure this way.
    Taking a break from car audio to become a better fisherman. It's paying off

I found that the top part of the "wire clamp" (not sure what the technical name is - it's a flat piece of metal that pushes down onto the wires as you tighten them) actually came off completely! This happened on multiple channels. It seems that the ferrules were just a little too "stiff" for the type of connections on the JL amp.

    I guess there is a reason why JL specifically says "bare wires" in the owners manual. :-)

    So I'd be careful with ferrules when certain types of amps!
    I donít have JL amps...but I have to agree with jtrosky here. I use ferrules for anything bigger than 8 AWG; but after that I find that they are just a pain in the ass. Not all the strands will go in (or the ferrule is slightly too big), but the big one for me is that at times the clamp doesnít actually lock the cable into the ferrule enough and the cables come out randomly. In fact because they are in a ferrule itís like they are sitting inside the perfect environment to allow the cables to slide out!

    In my latest install I didnít use any for the speaker terminals. You could solder them to the ferrules I guess...but I just twist the cable and put it where it is supposed to go. No problems and no assing about with goddam ferrules!!

    On runs of 0 AWG power cable etc. though yeah...definitely use ferrules.

    I agree ferrules don't make sense for most input terminals. Those grub screws strip out on soft bare copper half the time, forget about trying to get them to bite onto a metal tube.

    I later realized that the issue with ferrules and my JL amp was that the ferrules with the colored "collars" on them just didn't go into the JL Audio speaker terminals far enough (the JL amp speaker terminals are very "deep"), which is what caused the JL speaker wire "clamps" to come off (too much pressure was put on the front of the clamp instead of the whole clamp). I *could* have fixed that with the ferrules that don't have that colored "collars", but I left well enough alone - I didn't have any issues using bare wire ends. Turns out that the ferrules were a solution in search of a problem. :-)

    I have had the same issue on a few occassions. Really frustrating to have to go back on stuff like this (because of course it happens in the most awkward spots possible!).

    However I have a pile of high quality ferrule terminations that are destined for the bin or GumTree (an Australian local buy/sell site)...what was the other problem you solved with them? :thumbsup:
