Type of wire use for Big 3 Upgrade??

I had to look into my notes from years gone-by so here's another question. Crimping or Soldering the connection? This comment I would like to know.

Soldering battery connections is a BAD idea. Most people believe that soldering is superior to crimping, but this is not the case. Soldering creates additional resistance at the connection, as well as creating a connection with less current transfer capability. Also, soldering will create its own corrosion due to the inherent flux material.

True or False???

False................

Just look at all the soldered electrical connections in a computer.....
 
hmmm I would also like to see what peoples opinions are. I soldered my ring terminals on. But i never really thought of that comment^^^
 
If you solder it's best to use a Rosin-Core type solder, it cleans the wire as it bonds to it. I will not use anything but Rosin-Core when I am working on client's vehicles.

I believe the factory power/ground wires are 6 gauge, so going to 4, 2 or 0 will have some improvement, the bigger you go the better.

Searched up db link wire on ebay... Same retailer on Amazon is selling this on ebay for cheaper.

you can do eithier one whatever floats your boat im sure crimping them will be just fine soldering them wont do no difference just more of a chance there connectors are not gonna come loose on you crimping after a couple years or so one connector might winggle loose
 
crimp vs solder

Aircraft electrical connections aren't soldered because under certain conditions, when not strain-relieved, vibration can cause cracking of the wire at the rigid solder joint. Weight is probably an issue too.

That said, precautions that apply on aircraft are not always applicable to cars. I always solder, but don't run the solder down the wire past the connector creating a long, rigid, 'stick'. Rosin core solder is fine, you can clean it with alcohol. You'll have zero corrosion issues at the wire/terminal interface using solder.

What is a "Big 3 Upgrade"? Heavier gauge battery wires? Trunking the battery?
 
You want SGX (extra thick cross-linked polyethylene)insulation on the wire, cross-linked polyethylene is the insulation currently recommended by SAE standards for under hood use. Don't upgrade the size of the wire while downgrading the insulation. http://kayjayco.com/tech125CWire.htm

Solder the connections with rosin core solder, much more reliable and better continuity over the long run.

Thanks for the link VERY INFORMATIVE.
