This is not a good idea for heavy gauge power wire that you will be putting a heavy load on. Part of the process of pressure crimping is to pressure fuse all the strands of wire together by expelling the air out of the connector thus eliminating air gaps that will cause arcing within the connector, air promotes pitting and corrosion of the wire in the connector as well as allow pockets that water can sit if it's an exposed connector. Which will cause the connector to fail over timeCrimping large terminals like that I use a hammer and a flat tipped chisel.
Let me clarify, I use the hammer and chisel to partially crimp the terminal so the wire will not fall out when I am soldering it. I do not just crimp any terminal regardless of size. All my connections are soldered.This is not a good idea for heavy gauge power wire that you will be putting a heavy load on.

To be a certified connection you need to use the correct die and connector.
I used to install equipment on -48v DC power systems and have been through lots of classes.
Go to a stereo shop and give them a 12 pack to use the proper crimps and dies, or buy the correct tools for the job you can get a manual greenlee crimper for about 75 bucks, that has dies from 8 awg to 0 awg
i use blue-point cable cutters. i think they are like 30 or 40 bucks. great tools. for stripping i use the same tool to cut through the insulation. for crimping you can go to a stereo shop. they will have either a big set of ratcheting crimpers or a die and hammer style. i always crimp those style connectors then it solder the wire to the connector with a torch and heat shrink the ends. it makes for a really clean and solid setup.Crimping is a bad idea and typically fails over time.
First get your 2ga. at a welding supply. You can cut it with a hack saw if your careful and have a good blade. The outside jacket or insulator can be easily cut and stripped with a razor blade knife.
Get the connecting ends/lugs that have a cup to fit the cable into. Put the lugs (one at a time) in a vice and heat them up with a blow torch and melt the solder into them about 1/2 of the depth of the lug. Once up to temp the solder will pool and then you can slowly dip the stripped ends of the cable into the connector. Hold the cable into the lug until the solder solidifies (about 45-60 seconds).

I build emergency vehicles for a living and thats the exact way we do it at our shop. Although when it comes to crimpers, i prefer crimpers with the little nipple on the end. I've had much better success with that style vs. the racheting crimpers.i use blue-point cable cutters. i think they are like 30 or 40 bucks. great tools. for stripping i use the same tool to cut through the insulation. for crimping you can go to a stereo shop. they will have either a big set of ratcheting crimpers or a die and hammer style. i always crimp those style connectors then it solder the wire to the connector with a torch and heat shrink the ends. it makes for a really clean and solid setup.
as you know i built emergency cars for a while too. secret service, undercover IRS, some specialty police vehicles more along the custom lines. we had to do a lt of vehicles that didnt have any accessories made for them yet.I build emergency vehicles for a living and thats the exact way we do it at our shop.

Use the cable lug that web shot posted, crimp it with a die and hammer (Made specificly for crimping large gauge wires), and then solder the wire to the lug and heat shrink it. Never had a failure yet.
IMHO-this is one method i like i'm NOT an expert, but am a licensed electricianI am getting ready to install a cutout on my Warn XD 9000 and need to cut and crimp new lugs on the 2 AWG positive lead. Need recommendations on tools to cut and crimp.
Ah ha! This explains why you have all those lights on your rig! :bigthumb:I build emergency vehicles for a living and thats the exact way we do it at our shop.

Cutting, something like this: Cable Cutter
Crimping large terminals like that I use a hammer and a flat tipped chisel. If you can you should also solder the terminals. That will ensure you don't get corrosion inside the terminal for the long term.
