lotus Posted March 13, 2012 Author Report Share Posted March 13, 2012 i think the stock wiring is 8awg that leads to the battery postive. i went to a shop and they told me to do the big 3 and connect my 2nd battery would cost around $300... so all i wanted too know was if i used 4awg with nothing else added, would it be safe without any other battery added and would it increase a little efficency. Its only 1500rms and i dont plan on upgrading in this car. im fine with it now but i just want to be at a safe voltage without spending a lot of money. 2010 Cobalt LT Coupe Subs: 2 American bass XFL 12s Amp: Crescendo BC3500D Big 3 in 1/0awg 29hz box stinger volt meter 2nd battery Deka 9a31 pioneer DEH-9400BH Link to comment Share on other sites More sharing options...

I'd save yourself some money and do it yourself, yeah it may be frusterating and annoying to get to certain spots. But at least you learned how to do it yourself while saving yourself 300 bucks with the satisfaction of knowing you did it. As for battery wise.. couldn't tell you man im in the same boat as you trying to find out. Check out my build log: http://www.stevemead...60#entry1958353 Different folks have different strokes.

TheNewbie Posted March 13, 2012 Report Share Posted March 13, 2012 i tried but i have to take the the bumper off to reach the bolt on the alt Well then looks like the bumper has to come off just think about it this way.. there going to go through the same process as you except your doing it most likely slower.. take them (no idea how long it takes for big three.. doing it myself but!) 2 hours, takes you.. 4 hours.. your making 75 bucks by doing it yourself rather than having them do it for 150 bucks an hour. I'd keep trying man. Even if it takes a couple days who cares, last you learned how to do it for next time. Just my 2cents.

TheNewbie Posted March 13, 2012 Report Share Posted March 13, 2012 OP weather you do 2-3 runs of four gauge or a run of 0 gauge is completely up to you, just at least spend a couple days trying to do it yourself before you pay for it, here is a link to help you get it done, and if you have questions well that's what this forums for.

snafu Posted March 13, 2012 Report Share Posted March 13, 2012 Why is everyone so offended when a shop quotes labor? There are MANY qualified installers out there who have a solid grasp of automotive electrical. Some of them have spent years learning the trade and have thousands of dollars in tools to back it up. Personally, if I was tasked with doing this upgrade on your Cobalt, I wouldn't even entertain it for less than they quoted. The link posted is helpful, but is really not applicable to this vehicle.
