Big 3 Wiring Question

[jgruberman 10+ year member]

I know you're supposed to wire the big 3 over the stock wiring and not remove any of the stock cables.

BUT... can I wire the cables in completely different locations? The ground is very hard to get to on the engine block, but there are other screw holes on the top more accessible. Can I use any grounding point, or does it need to be the SAME point as the existing ground?

a lot of the times the best grounding points are not the factory locations. personally I'd get a DMM and check the resistance at a few points and choose the ones with the least resistance.

So I can leave the factory locations, and ground my 1/0 wire to other locations? I already have 1/0 power to the amps.

yes, if you have a DMM check to see what spots give you the least resistance so you know that it's a good ground.

Adding this latest question to your last "big 3" thread would've been stupid. Congratulations on making a spectacular decision.

If you check that thread, you'll see that yet again, you've made a sarcastic *** of yourself //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif . Didn't get any responses, so I figured I'd post in the main forum for quicker responses. And before you go comparing the timestamp of the first post of this thread to my last post of the original one... I didn't wait very long, no. But I got quicker response with a new thread than I did posting to the old one.

if you check grounds for resistance - use a 10 ohm resistor in series to operate in the range of the DMM. measure the resistor first, then measure the ground resistance (disconnected from battery), then subtract the two.
