Best splice connectors for new CD player?

[froglady99]

I recently bought a new CD player for my 2003 Explorer XLT. The new CD player has its own wiring harness, and I bought one that will plug into my car. But I'm having the hardest time figuring out which splice connectors would be best. I've read all sorts of articles and stuff online, but it seems like just when I think I've decided which connector to use, I find an article saying all the reasons why I shouldn't use it.

I've never spliced wires before, and I just want to make sure I get them connected well enough that they won't come apart anytime soon. Where I live, the temperature regularly gets well below 0, and if it's that cold, there's no way I'll be out there trying to fix my CD player wires.

The connectors I already have are Scotchlock, heat shrink butt connectors, and the kind you twist on (the kind that looks like a tiny toothpaste cap).

If you could tell me what connectors you used that worked, maybe that would help me decide which would be best.

For stereos, I've seen used and have used these:

Not from this place, but they look the same.

The best way is solder wire and cover with heat shrink tube. Good mechanical connection, good insulation, minimal size.

I solder when it's more of a permanent connection.
If you decide to put in a different stereo later and you soldered the connection, you now have to cut the wires back farther, which gives you less wire

From his description it appears that he is splicing two connectors together to make a harness adaptor. I would consider this a permanent connection.
Since this has to cram in the dash behind the radio less bulk is better.
