How about you take it to a local car audio shop and have them crimp it with a heavy duty wire gauge crimper to ensure the connection won't come apart... Then if you'd like you can probably use a torch of some sort to heat 4 gauge enough to solder it But I don't believe its necessary... They might charge you a labor fee but it shouldn't be more than like $5, just my .02

You could also use a tool thats made to crimp 4 gauge wire. Check West Marine or Boats US. The wire sets on the lower half of the crimper and you hit the upper half with a hammer. Costs about $32 USD. Made by Ancor.

Doesnt anyone use a bench vice to do this. Thats always how I crimp on the power cable ends. Then you just solder and your gold.

I actually use a specialized crimper for this. I routinely use 6 g, 4 g, wiring for emergency vehicle applications. We use only copper terminals for ease of crimp and soldering. If we make the cables on the bench, we solder the connectors on them using just a regular propane bottle torch. The connector is held in the vise, I put in a "slug" made of coiled solder in the connector, I heat the copper until the solder melts, hold the heat on it for an additional 3-5 seconds, remove the heat and insert the cable and hold in place. Just make certain the flame stays away from the solder as you do not want to burn the flux. If you do it correctly, you will make a very good connector. Holding the cable in while heating the connector just makes for a messy installation as it will start to melt the insulation off of the cable.

Personally, crimping with hammers, vises, doesn't make for a good connection and looks tacky. Try to achieve a method that pinches the middle, very much like a non-insulated butt connector crimp would do.
