.4-.5 is about the lowest you want to go on a stock setup. I run it all day long on a couple of my stock grands. Below ~.45 you will start to get button melt and spring sag.
The collapsed spring is just nature of the beast if you're playing with .3. It did it's job. I've blown a few fuses when my super-sub setup shorted.
The benefit:risk of running .3 on a stock isn't worth it. Unless you are fused and can replace it for a few pennies... Melting $4 springs gets expensive.
My advice: Stock box, stay at .5 or above. ANd if you've modded one... a .5 performs closer to .25-.3 anyways.
do you mean the fuse, when you say modded?
hell i haven't even learned how to make a 10a fuse neg. contact, but if anything, that's where i should start; way back in the Reo micro threads.
I'm a bit concerned that i won't be completely happy with the new spring on Rob's kit, but knowing Rob, it should be a great improvement.
I'm thinking we're getting close.
- under .6 ohms, stock, you're going to have trouble; misfires, pos pin maintenance, spring overheating, collapsing.
Problem is once you get a taste of sub .6 ohms, its hard to settle… and yeah, that's given you are losing some in v drop along the line with stock rig.
