How to set up arduino uno with 4 x 12v dc motors

Hey everyone, I need quite a bit of help on this one. I was trying to create a car that would use four 12v dc motors and an Arduino uno r3. I'm new to electronics and I just wanted to start with something like this.

Parts I have:

h-bridges
12v lead acid battery
wires
breadboard
Arduino Uno rev 3
12v d/c motors

I'm trying to limit it to these parts I set up something like this (minus the "radio box", that was cut out):

The black chips in the middle are the h-bridge chips. And instead of the 9v battery, I'm using a 12v battery.

The code is irrelevant right now, I just want to make sure my electronic set up is accurate. If you see anything wrong, PLEASE let me know! Thanks in advance.

Hi Grandmaster,
please take extreme care when using a lead acid battery, they can output a huge current if shorted.

I'm quite careful! Which is why I'm making this post just in case I'm doing something wrong!

I still need help guys...
