    Crimp tool for 4 AWG and larger power wire

    Hey Guys,

    I'd like to re-do my power wiring, and I have a couple buddies with upcoming car audio projects.

    Therefore, I wouldn't mind investing in a decent crimper (I'm not a fan of soldering large power connections). I'm obviously just a hobbyist, and I wouldn't use it THAT often, but I like having decent tools. I'd probably be willing to spend a hundo or two if it's actually worth it.

    Is my best bet simply one of the cheap hammer-type deals, or is it worth paying more for a more serious tool?

    Thanks,
    Matt

    Do you have a bench vise? That will clamp harder than any hand tool.

    I bought one of these Hydraulic crimpers from Harbor Freight: Hydraulic Wire Crimping Tool
    I was surprised at how good of a job it did. One word of caution though...I had to carry my first one back because one of the rings was twisted so it leaked oil, so make sure to open and inspect it before leaving the store.

    Didn't know Harbor Freight had those. Need to stop by and get a set.

    Been using one of these for years.



    Works pretty good. Results can be unpredictable.

    I've been impressed with the HF crimper, you just need to make sure the ring terminals you are using isn't over-sized or else it won't fit between the anvils. It makes clean hex-shaped crimps, but when I did mine, I went a step further and added solder.

    Over Achiever!! I'm glad you mentioned this crimper as it's a must have for the money.

    The hydraulic crimper is the way to go.... I just solder. I've seen the cutaway of one of those crimps, it's damn impressive.

    I don't like soldering that stuff. First, my "high quality" Stinger power cable's jacket caught on fire. I will never recommend anything other than welding cable from here on out due to that. Welding cable doesn't catch on fire.

    Real crimps with a REAL tool. Hammered crimps are not good crimps IMO.
    Just because you don't understand the data doesn't mean it's not relevant.
