also maybe add another (or bigger) earthing cable from battery to the chassis... if your now grounding two amps (each one with 4G wire) dont forget your battery still has the single 4G connection to the chassis... to keep it all even id either upgrade to a single 2G (or even 0G) earth from battery to chassis, or add atleast another 4G...
This is how it is earthed atm, is this the best way? If not where should I ground it?

These are the only other bolts I can find near the side cushion. 1 holds the seat belt, the other holds the side cushion in place.
*EDIT* I only have 1 4g earth running from my capacitor. I have 2 8g earth wires from each amp running to the cap.
yeah thats fine being earther there... but i would still upgrade at the other end....
its like making a three lane highway from canberra to sydney... then just before you get to sydney, making it only 1 lane for the last 50kms.... yes all the cars will still get through, but no where near as many as you could if it continued as three lanes...
if you get what im saying? :confused:
I cant believe what BS this is and that reasonably intelligent people here like you guys fall for it. I mean .2 ov a volt is going to make zero impact on the car no matter what you want to believe. Its a placebo FFS.
0.2v increase at 600-700rpm by just adding one 2G cable is a massive increase electrically... it might not sound like much, but when everything in the euro uses power to run, it can make a very big difference... and i only measured voltage, im sure that the alternater would now be running alot better aswell, meaning it can take a higher current draw...Quote:

stock car uses 4G cable to run all electrical systems...
if you then add another two 4G cables to run two high power amplifiers... youre still only pulling all that power thru the one earth cable..
it needs to be upgraded...
