I wasn't but I would suggest a larger wire gauge. Here is a link you may find useful: http://www.the12volt.com/info/recwirsz.asp

im using the monster cable 500 watt amp kit 4 awg

and 8 awg for the amp to sub

upgrade the grounds the big three and you'll most likely be a-ok

The ground wire is even more important than the powerwire

Larger gauge wire will help. If I were putting a system like that in I would also use a capacitor (roughly 1Farad for every 1000 Watts of system power rating). I have used them before placed as close as possible to the amp and they do work. The capacitor provides large amounts of instantaneous power and recharges itself when not in demand so it is not continously using current as said in an earlier post.


btw....never cross terminals with screw driver by accident....very painful!!

im planning to upgrade my speakers later down on the road so should i get 1 or 2 farad and what brand do you guys recommend...thx for all the info guys

It really depends on the power rating of the amplifier you use. A good rule of thumb is 1 Farad for every 1000 Watts.

you dont need a capacitor, dont waist your money on a capacitor.

get a yellow top optima and do the "Big three"
that will fix your problem.


here you go:

it show you, and explains how to do a Big three

thats what you need. not a capacitor.

has anyone here done the big three to the g37 yet

armen818

Its simple, just follow the link

well i did read the forum but i dont want to be the first one to do it to our car i would rather wait for someone who did it already and pst up some pic as to where they put there ground and so on..kinda scared to do it if im the first one dont want to mess anything up haha because im not no pro at car audio

Capacitors maintain charges for nanosecond and need to be replenished after large transients. Upgraded alternator is the way to go.

What amp and how long is the run is the question?

I'm almost positive that "Big 3" is the same as a "grounding wire kit" which you'll see many have done.

Can anyone else verify?

Betty's Garage grounding kits upgrade two of the "Big 3" (battery negative to chassis and chassis to engine block on each side) in either 8 AWG or 4 AWG. It doesn't have a connection from the alternator positive to battery positive. It would be a difficult install on this car that most would not want to do as DIY. If anyone wants the alternator + to battery + cable to complete the "Big 3", I'll be glad to fabricate one for you if you get an accurate length measurement.

I too am a believer that a capacitor is a waste of money, but plenty of professionals believe in them. I don't. I personally think better grounding, a beefier alternator, and second battery are MUCH better solutions. I don't want to run a second battery and our alternators produce sufficient output IMO, so grounding kit it the way to go for me.

Thanks for your clarification BB.
