Loudintha509 Posted January 25, 2010 Author Report Share Posted January 25, 2010 I already have the wire just wanted to know if it was worth doing. I got a hella good deal a couple days befroe xmas on four hundred foot rolls 2 blue 2 black. i think people who have neg. comments suck. I was not trying to be rude by asking the guy if he seen any builds here. He just never seen anybody run neg fromm front to back. I have just finding out if its worth it.

97SSBlazer Posted January 25, 2010 Report Share Posted January 25, 2010 Doing a run of negative from front to back will give you a better connection than grounding the back to the frame. Like one other person said a ground should not be longer than 3 feet, well if the current only has to travel through a huge wire that is 10ft+, it will still be more efficient than traveling throughout the whole frame THEN to the wire. Bottom line is a direct connection is better than grounding to the frame, but if you do not have the $$ for the wire to do so, just go ahead and ground it to the frame, it still works. That's what i thought. I have seen people drill holes through the sheet metal in their trunks and go straight to the frame. Like I said i have never done it my self so i don't know. I always do the "big 3" and call it good. Most people around MI don't have anything over 2K watts so that maybe why i have never seen it... Quote lower tuning is just hard. I was surprised how loud 145 sounds at 35hz, and how quiet 145 sounds at 50hz. -= 2005 Tahoe LT =-Head unit: Pioneer AVH-X5500BHSSource: iPad Mini in dash Subs: 2 T1 12's Sub Amp: T1500-1bdCPWire: Rockford Fosgate 1/0 awgSignal Cable: MonsterFronts:Stock Bose for now:)Rears: Stock Bose for now:)MIds/High amp: Stock Bose for now:) 2005 Tahoe Build Log: http://www.stevemeadedesigns.com/board/topic/172529-2005-tahoe-my-17th-vehicle/ 2001 Monte Build Log: http://www.stevemeadedesigns.com/board/topic/160030-2001-monte-carlo-my-16th-car-lol/page-2#entry25309381997 Tahoe Build Log: http://www.stevemead...oe-6-15-rf-15s/2001 Impala Build Log: http://www.stevemead...katzkin-inside/ Link to comment Share on other sites More sharing options...
Stephen Posted January 25, 2010 Report Share Posted January 25, 2010 Adding a piece of 1/0 from my alt case to my - battery post and running a 1/0 ground from front to back was the best thing i did for electrical. Quote you can cook bacon shirtless if you're not a pussy...lol not hatin, but am i wrong here it looks as if the amp is not grounded its hooked directly to the battery. it that the way it should be.

mr.p Posted January 25, 2010 Report Share Posted January 25, 2010 the chasis has far more surface area than a single run or two runs of 1/0 will ever have. If you properly ground to the chassis/frame you will not need a ground run. measure your voltage under load at the front and the rear of the vehicle simultaneously and see what it does.

Loudintha509 Posted January 26, 2010 Author Report Share Posted January 26, 2010 Well guys I added another run of pos. and two neg. and It was worth it. I ran one from the batt. and one from the alt mount. When I find my volt meter ill know how big a difference it made. I never got an answer from the guy on this forum so I went and bought three new g31's. Quote I wish every body had beat so I wouldnt have to turn my shit down.

treossi Posted January 26, 2010 Report Share Posted January 26, 2010 i like ground front to rear batts as well as ground the back batteries to the chassis.. the back battery must be grounded in a way that it is connected to a nice chunk of steel.. i hate seeing people ground the rear battery to a 1/8 inch thick.... or thinner.. piece of shitty sheet metal with paint still on it...

Loudintha509 Posted January 26, 2010 Author Report Share Posted January 26, 2010 When I find my meter i will see if it matters. I have a bolt in my frame under the batts. ready for the test. If I dont find it tonight I will go get my brothers. If its the same im taken the wire out. Quote I wish every body had beat so I wouldnt have to turn my shit down.

Blackedout Posted January 26, 2010 Report Share Posted January 26, 2010 I'll agree that the chassis has a lot more surface area, but there are a few things that mess your theory up. 1) Conductivity of copper vs steel. Copper is far more conductive. 2) Welds and spot welds. The chassis of a car is no better than 4 Gauge copper wire... Run a dedicated positive and a dedicated negative. Drop the necessary $50- $80 to do so, throw it into the car and if it doesn't make a difference fuse it and use it as a positive... Either way, the less resistance the better.
