I just installed my subs in my G and was wondering if anyone knew the voltage coming out of the stock head unit? I am trying to set the gain on my amp and knowing this would make it a lot easier. I have tried searching and haven't had any luck.

 

Use a voltmeter and measure it

Telcoman

 

Where would I measure it?

 

Can anyone without a grounding kit measure their voltage?

I'd like to know as well. I want to compare how well my diy grounding kit is doing. I didn't feel a noticeable difference in shifting through my 5AT gears as some have claimed there would be

 

In my experience the "better shifting" is a placebo effect. I though it felt faster too but after looking at some videos I took, it was still shifting at an average of .6s.
