3 D3100s Under Hood of Tahoe or Escalade?

[Captain Stupid]

Hey all. So, I'm thinking that putting 3 D3100s under the hood of a Tahoe/Escalade is a do-able task. Just wanted to see if anyone has pics they can post of how they mounted the batteries on the passenger side. I already have the first D3100 mounted under hood in the stock location. Pic below. I think I already have an idea of how I want to do it, but I'd love to see if others have done something I may not have thought of before I start cutting and welding.

Below is a pic of the passenger side under hood. I am certain I can get a second D3100 up next to the firewall if I move my radiator overflow forward about an inch if I lay it on it's side and make a bracket strong enough to withstand the weight. I am thinking the third D3100 will go where the air filter inlet is now. I'll just need to shorten the tube a bit and move the air cleaner out of the way.

So, any ideas and pics of your mounting technique would be appreciated.

I have a 06 yukon ( same as your esky) and have a d3400 on the passenger side using a factory tray and hold down. Its a pretty tight fit already and almost sure a 3100 will not fit.

Pics?

You're right that the D3100 won't fit with the factory mount and hold-down. To fit the D3100 I'll have to fab up my own brackets, lay the battery on it's side, and move the radiator overflow forward about an inch. I've already checked all that, just looking to see who else has done it and how they built the support.

I cant find any pics of the setup. I'll take some tomorrow and post them. All you have to do is get a battery tray and hold down for a H.D. suburban. Cost is like 40$.

Why can't you put the other 2 bats in the rear?

Might be better in the rear having the batts closer to the amps

Believe it or not, I actually drag race my Escy. NHRA does not allow batteries of any type inside the vehicle unless they are in a sealed, vented box, or behind a sealed firewall. Also, I tow my REAL race car with the truck, so between the sub box and the tongue weight of the trailer, I'm trying to keep from putting more weight in the rear.

Pic racing with the old 22" wheels on it....

I still dont think the 3100 will fit there even with a modified tray and laying it on its side. Its about 3" longer then the 3400 and the 3400 barely clears the hood due to the "slope" of the hood. But you never know, try it and let us know

That's pretty cool, do you race with subs in or do you take them out with the box?

Maybe there is just a subtle difference between the Yukon and Escalade in how the hood is shaped there? Dunno. I should have taken a pic when I test fit it in there. Couldn't leave the battery there, though, because I wasn't able to secure it at the moment. It fits for sure, just need to fab up something custom. I know I can't be the first one to do this?
