This feels like kind of a stupid question, but like the title implies, I'm doing the Big 3 on my GS400 and am wondering if anyone can point me towards the engine block ground(s) location that I should be upgrading?

I've done this on other cars before but am not finding the ground wires in the GS when I take a look around, pics would be awesome but a description of where to find them would be very helpful as well.

 

So, like a homemade grounding kit? I've wondered about this myself...

 

Pretty much, the big 3 usually consists of using larger gauge wires in addition to or replacing the factory battery to chassis ground, alternator to battery power wire, and engine block to chassis ground(s). The factory wiring is very restrictive when you're running an audio system.

 

Anybody out there?

 

i need to do this on my gs430.....im lazy and time is sparse for me. i wanted to buy a premade kit but cant find one

 

I got the Apexi Versa edition grounding kit for my GS300....my engine block ground was somewhere in the back of the engine...underneath the engine cover.

 

just find any bolt on your block and use it. It doesnt matter what you use, as long as its on the block. Many people (including I) use the mounting bolt of the alternator housing as one of them and yea theres usually a ground from the firewall to the block.

 

i had it on my acura, i liked it and it looked nice. always wanted the HKS one though

see remember that email i sent you....you should be making us some.

 

kyle u ever do yours? i started mine in post # 54 with a few pics, i followed close to 2 of the oem ones. waiting on my alternator to finish the last one

thanks but IF u had scrolled to post above yours you would see i already started making mine, plus daizen doesn't have one for the gs430 just the gs400 and couldn't even find the actual part # for the gs nor a price nor a price for it

 

Kyle, I did something similar in my old GS.

get some 4 gauge and do it yourself not hard at all if you have tools

 

Thanks for the replies, I'd forgotten about this thread! I used a few of the pictures in the thread(s) Dave linked to as a starting point, found it after Frankdorns mention of grounding kits led me that direction for a guide. Gotta order a few more ring terminals to finish things off to my satisfaction.

 

no 4 gauge....use 0 gauge

where u ordering from kyle?
