Zx2guy19 Posted July 12, 2015 Report Share Posted July 12, 2015 Hey everyone, relocating the battery on my 240 today. I have a high quality 4 gauge wire (fine strand) that's just the amount I need. I'm reading a lot on forums of most people using 0, 1 or 2. It's a Bosch gel battery, 740 CCA. Overall question: is a high quality, fine strand 4 gauge wire acceptable for a battery wire to the trunk? Quote Link to comment Share on other sites More sharing options...
Cordell Posted July 12, 2015 Report Share Posted July 12, 2015 Size of the battery has nothing to do with what size wire you need, it's all about how big of a load will be on the other end of that wire. I am not an engineer nor do I want to help you calculate the proper size, but I would not skimp here. Bigger is better in this situation. Even if the wire is "just big enough" running a larger wire helps keep voltage drop to a minimum and will just make everthing electrical on the car work better, ie more reliable and consistant.

Zx2guy19 Posted July 12, 2015 Author Report Share Posted July 12, 2015 I meant just the amount I need as far as I length (I used it on last car but that doesn't make it right). I'll go to lowes and get a bigger wire, no biggie. Better safe than sorry. Quote Link to comment Share on other sites More sharing options...
BIGGU Posted July 12, 2015 Report Share Posted July 12, 2015 on my SC for the longest time I used 4 gauge for a long time but I did eventually switch it out for 0 gauge. Quote Link to comment Share on other sites More sharing options...
Geeesammy Posted July 12, 2015 Report Share Posted July 12, 2015 I debated it on my car, waiting untilt this winter but I would say at a minimum very high quality 2ga wire with great connectors. I'm using 0ga Mil-Spec just to be safe as as some sheathing to ensure it doesn't rub through Quote Link to comment Share on other sites More sharing options...
spankis Posted July 12, 2015 Report Share Posted July 12, 2015 I need to replace a few cables on my truck where the crappy lead factory terminals are failing. Reading up on replacements, there is a big debate between crimped on or soldered on terminals. Any thoughts on what's best? Quote Link to comment Share on other sites More sharing options...

Reading up on replacements, there is a big debate between crimped on or soldered on terminals. Any thoughts on what's best? I've always been against soldering as it usually becomes very brittle. If you get a good set of crimps and then heat shrink over that it holds up very well in my opinion. Quote Link to comment Share on other sites More sharing options...

Zx2guy19 Posted July 12, 2015 Author Report Share Posted July 12, 2015 I used 4 gauge. The car has been sitting for 2 years and I wanted to hear it run today. I'll probably upgrade it this winter, but I couldn't find any place open that anything better in a high quality wire. That said, the car started right up and sounds great. I used a 6 port power block by Raptor Audio to split all the front wiring into the back. I have to get a battery box but otherwise, it's ready to tow to IPS.
