chesthertZ Posted December 30, 2007 Author Report Share Posted December 30, 2007 Can be any colour you like as long as it's equal or larger size than your power cable, my earths are blue . Also make the earth as short as possible. How long is it? i have about 30cm left, i dont know how many that inches that is for you yanks. anyway if i change the earth that running from the amp to the body of the car, do i need to change the one thats running from my battery to my car body?

Charger Posted December 30, 2007 Report Share Posted December 30, 2007 Yes upgrading the battery earth cable is also crucial. As mentioned earlier your circuit is on as strong as its weakest link. And infact the circuit does not just include your amp's wires but also the wires coming off the battery. No matter how great your massive amp power cables are and if you have perfect earths up back, if you have a single crappy 8awg factory earth coming off the battery it will be the weakest link in your system rendering all those upgrades near useless . I had five 0awg earths coming off my front battery when I upgraded.

Charger Posted December 30, 2007 Report Share Posted December 30, 2007 How much power, in RMS are you running per amp, and how many runs of speaker cable come from each amp. Could you get a picture of the cable you are using?

Torres Posted December 30, 2007 Report Share Posted December 30, 2007 yes...i still stand by my statement i have 3k going through my 8ga wire, so you're still probably in the safe ballpark. oh and by speakers i meant the woofers. my bad Quote Link to comment Share on other sites More sharing options...
