How To Crimp 4awg already in a Car

Ok today I noticed that my orignal 4awg crimp on my power connector to my wifes brutus was starting to get loose, even though I used a hefty hammer on the orignal install to crimp it

So how do I now make the crimp more secure, I cant take the wire out of the car to put a new connector on it, Im not spending 200 bucks on a 4awg crimper, so what are my options?

Should I get a inexpensive solder iron and rely on the solder to hold it and handle the power?
Can I use a C-Clamp to crush it down?

Other Suggestions?

Thanks All

I would solder the terminals on, I have 2 4guage power wires running from the front to back and I soldered all of the terminals and have not had any probles mith them.

Cram the wires together, use a torch to heat them up then cram about a foot of solder in there and you'll be set.

solder it, or they do make cripers for 4 ga.. and i've never heard of them being 200, i had one that i spent like 22 bucks on (it said it only went to 6  but it did 4 no prob, the klein ones do it, i would prolly just crimp the hell out of it and solder it tho)

You got a part number and a place I can get one?

perhaps you could even take it to an install bay and get them to do it with the correct crimpers, which apply several tons of pressure and then fill it with a LOT of solder. The cheap handheld ones aren't that great. You need several tons do to it properly.

I thought of that but to 2 closest shops dont crimp or solder connections that big, they do the same as me just pound the hell out of it with a sledgehammer

Im going to home depot to pick up a torch and to radioshack to get some solder, that should take care of the problem

If you've ever seen my posts about using bolt cutters....

What you need is leverage, and bolt cutters will do just that.  If the cutter is old and worn out all the better.  I wouldn't attempt to solder without crimping first because you won't get a good electrical connection.

the klein ones are a "amtkl1006" 17.89 from AM distributors (tax id needed) they will do a pretty good job, like i said they aren't ment specifically for 4 ga, but they do it good with a little bit of effort, then you just solder a bit and it's perfect

am's number is 8883451300

I got it done, used some vice grips in fact broke them.. luckly they were craftsman so I got a brand new pair, then I torched the hell out of them and loaded it up with solder, these connectors are never going to come off again

Thanks all

this is what i use when i'm in your situation.  you can either use a hamer or some kind of vice to power the crimper. it's a lot cheaper than a crimping tool that comes with all the dies and whatnot.  i found this one for 30 dollars.  i know snap-on makes one too.

Stinger also makes a great accessory for connecting 4g (part# scoup4) msrp $6.00 or 1/0g (part# scoup0) msrp $7.50.  These are basically barrel connectors with allen heads.  You might want to through some electrical tape around the terminal for extra protection against wear. Then slip on a some heat shrink tubing and you should be set.

here's a crimper for large awg wire for 35 bones, plus shipping.
