Questions about big 3 and adding a cap

[incognyto]

I just grabbed the biggest battery that I thought would fit... ripped the stock tray and battery cover out and extended the hold down clamp a little.... as you may see in the pic... another thing I did was remove the daytime running light's (you may not have if your not in canada) fues from the fuse box so I don't have the damn light's running all the time... and I can turn them off when I get somewhere without haveing to put on the ebrake and restart the car!! I think every little bit of voltage and current will help with my boom
