    Is this a speaker cable or instrument ??? it had two 1/4” connectors and i tried changing it to speakon on one end … i has very low volume … i then took the 1/4” end and attached to the other speaker cable i had with two speakons (one i took off for the first cable ) and now i get good volume … the original cable that had 2 speakons is 12 gauge … B47F4B7A-A4FB-4DEC-BBF6-9214A60BA660.jpeg 17BF3A22-4AFA-4056-BD5D-EEEA43690A61.jpeg 3FA31601-9CA3-4AF5-B29C-404E67FB9351.jpeg EE5095DF-02A5-476A-AB53-FF40810BB828.jpeg

    Speaker cable, but the plugs you are using are knock-off plugs that are notorious for intermittent problems.

    Suggestion… use genuine Neutrik plugs.

    In the real world this thread would be finished...... but in TB world we'll probably get another 4 or more pages of posts. :roflmao:

    When you open the cable, the wires show you if it is a speaker or instrument cable.

    A speaker wire will have two colors inside the outer jacket. When wiring a speakon cable, look for markings on the connector. [+1] should be the wire from the ¼” tip on the other end, [-1] should be the sleeve. This keeps the phase wiring of the speaker correct.

    This soldered connection is not done well. The red wire joint has black impurities. Even worse though, the upward hump puts the tip too close to the metal cover which is the shield. This can cause a short.

    Also the crimp is on the wires, should be on the sheathing/jacket.

    ok so i had 2 wires a speakon to speakon and a 1/4” to 1/4”
    before soldering i tried removing one of the 1/4” from the 1/4”to1/4” and just add a speakon conector since those are screw ons so … the result really low volume … then proceed to solder a 1/4” tip on the original speakon to speakon cable (the bad solder pic lol) and I had normal volume , later on decided to check it again and with the same cable original speakon one and had low to no volume … switched speaker cables and same … well decided to use a different instrument cable and had normal volume with both speaker cable 1 & 2 … hopefully nothing got damaged in this process … i will fully test everything tonight … but if it works it works right ???

    Well, the OP's question was accurately answered early on, but I'm going to pile on about the quarter-phone plug as well. I'll venture a guess that this has been recently fabricated by a non-professional, and I offer as evidence: the scrap of outer jacket on the floor in the first pic, the poor termination itself, and finally, the absence of the back shell. I think if the back shell were there, this quarter-phone termination would not work. As pictured, it probably will work for a while, but the quarter-phone obviously needs to be re-terminated.

    Edit: I'm glad to see the OP's 'confession' confirms my theory about the non-professional soldering job. I'd highly advise trying to rework this quarter-phone termination, or you'd probably be better off just buying the prefabricated cable that you need. Soldering 16-gauge speaker wire to a quarter-phone is a bit more tricky than some other soldering jobs -- it takes a seasoned hand, IMO.

    I'm highly opinionated and extremely self-assured
    This may be semantic/pedantic, but in my world, if it’s not Neutrik, it’s not SpeakOn. Those other brands are just “locking connectors” that may or may not work.

    Real Neutrik connectors are nearly foolproof. Just make sure you cut back to stranded cable, without any solder.

    Don’t cheap out on vegetables, tires, or speaker connectors. The $$ savings are simply not worth the !*@! headaches.

    Also check your polarity - I would think that white would usually be used as "+" on this cable, but would make no difference if hooked up correctly. Also, check the Speakon for polarity - I have found that these "aftermarket" Speakon connectors are poorly labeled.

    i had all those wires with me … wasn’t really looking for a discount or knock offs … my main concern is the bass amp head and cab not getting damaged … is my first time trying to make stuff up with wires and connectors ….

    Well that quarter-phone termination could very well short out -- that would present a very real risk of damage to your amp. The cab will be fine.

    Buy what you need and steer clear of anything that doesn't actually say Neutrik on the Speakon connector. Did you put that one on that cable? I'm asking because I'm a little surprised to see a counterfeit NL4 on a ProCo cable -- they generally have a pretty good reputation.

    It's definitely a speaker wire. If it doesn't work after you wired a Speakon connector on it, either the connector is not good (as per Agedhorse's input), or you wired it wrong. There are 2 and 4 pole Speakon connectors, so some knowledge of what you're plugging it into, and how to wire it is key - they're not quite as simple as 1/4 inch plugs.

    OP, I’m confused by your references to “instrument cable”. I don’t see any pictured, and you certainly don’t want to use them for amp to speaker wiring. If you were simply switching instrument cables between your guitar and the amp input, that should have no bearing on the speaker cables. However, a bad instrument cable can cause lowered volume and all kinds of other noise that can be heard through the speaker. If the problem is in your instrument cable, you likely didn’t do any harm. If it’s in the speaker cable though, much harm potential.

    so what’s the easiest or best way to know if I did caused harm ?
