Our battery box was sized for a Group 24 battery which is a very common battery size. It is also larger than the stock sized battery and puts out more cold cranking amps. You can use the stock battery; you just need to wedge something in the box so it doesn’t move around.

Wire, this is very important. We recommend getting nothing smaller than 4-gauge wire. We have used 1 O/T wire. 17 feet total. A good place to buy this is at a local welding store. The Ends have been crimped with battery terminals and headshrinked.

Removing the old battery is one of the first steps. Here are a few of the parts that were left over from the install.

It is said that putting the battery in the rear makes a better weight distribution.

After the box is mounted you will begin to run the wire. I tucked it in the rear interior panels. Then popped the right carpet trim piece off and feed the wire all the way to the firewall.

Something nice about the crx, there are 3 plastic tabs shown in this picture, you can easily set the wire in the tabs, which holds it nicely in place.

After you run the wire through the firewall you will need to cut it and install some type of distribution block. This block has 4 outputs of 8 gauge wires. 1 goes directly to the fuse box, and the 2 others where spliced
