YouWouldKnow Posted February 12, 2017 Report Posted February 12, 2017 I've hard this multiple times but it doesn't really make sense to me. Why would you want to keep your ground short? Either way you are connecting the ground to a metal piece in your car that flows to the front of your car and completes the curcuit right?.. plus wouldn't the best ground be to ground your amp to your batteries negative terminal, so lets say your battery is in the front of your car then that ground wire would be like 10 feet to get to the back of the car and connect to the amp

Wasteland_Audio Posted February 12, 2017 Report Posted February 12, 2017 Shorter wires = lower resistance = higher efficiency. There are a lot of people on here that know a lot more than me about all this but this is the basic principle. As white just said, electricity follows the path of least resistance. So the longer your wire, the more the power source needs to work to get it to the end of said wire. Hope this helps!

Okay sorry I am just confused because resistance (R) = V/I and wouldn't you have more current flow with a thick copper wire then with an aluminum frame of a car, plus the resistivity of copper is less than that of aluminum... maybe is it because R = rL/a and since an aluminum body has a higher cross sectional area then you would have a smaller resistance since its inversely proportional and all

Sorry trust me I am not, I am just trying to figure everything out before I install a new system and the best knowledge I have found has been from forums like this... I have a 2011 toyota corolla
06RTCharger Posted February 12, 2017 Report Posted February 12, 2017 Maybe if u think of the chassis as a big ass 4/0 wire, it'll make more sense. Generally a Front to Back single run of 1/0 would be less efficient than using a short run to chassis. But If u were going to use multiple runs of 1/0, then maybe Front to Back runs would be more efficient than using chassis. I guess the idea is u want to use the biggest conductor available for ur situation. Is ur wire a bigger conductor than ur chassis? Most times chassis will be a bigger/more efficent conductor due to its metal mass. Thats my noob perspective anyway. Hope it makes sense.
