Broke_Audio_Addict Posted August 25, 2015 Report Posted August 25, 2015 i like that option but would there be anything simplier ? Run a negative wire from the front to the rear battery and ground your amps at the rear battery. That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.
sundownaudio Posted August 25, 2015 Author Report Posted August 25, 2015 Use a dmm and measure the resistance between that point and the front battery. My guess is it's high which is no good. If however the resistance is real low you are fine. so i use the multimeter and put the probes one on the ground spot and the next on the negative terminal of the battery ? what reading would be considered as too high and low enough to be suitable ?

Broke_Audio_Addict Posted August 25, 2015 Report Posted August 25, 2015 From that spot to the negative on the front battery since that's where it wants to return too. .5 ohm or less but as low as possible is what you want. If it's over .5 ohm it's no good. That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.

dolarbilz Posted August 26, 2015 Report Posted August 26, 2015 how should i go about rectifying this ? best options ? personally I like one of these welded to a good spot http://www.knukonceptz.com/mobile-audio/installation-accessories/set-screw-terminals/sp/set-screw-40-gauge-ring-terminal-ground-lug/ You can weld aluminum to steel?

MotorCityFats13 Posted August 26, 2015 Report Posted August 26, 2015 the path of least resistance from battery to where you ground through the frame/body is only equal to a 4awg wire at best... it gets worse with the new silent metal that ford is using.... if you use a power wire larger than 4awg then it is best to add a matching ground path.... jl audio had an article on this but I cant find the post online anymore.... doug from soundman had a link to it on his forum 2 years ago and it was a good eye opening read!
jbeez Posted August 26, 2015 Report Posted August 26, 2015 There is a great post with a video on the boards already here: http://www.stevemeadedesigns.com/board/topic/147995-ground-to-the-chassis-or-run-a-ground-cable-ce-auto-electric-supply-partners-with-damore-engineering-to-answer-video-on-pg-5/
