Add-A-Battery Kits
We’ve been in and around car audio since 1984. Since then, we’ve never seen an easy way to correctly add an auxiliary battery. So, we developed two such kits. Either makes this a snap and takes all the guesswork out of this.
Doing It Right Requires:
-
- Proper electrical protection for both the primary and auxiliary batteries
- Correct grounding of the auxiliary battery
- Proper sheathing and mounting for running the cable underneath the vehicle
- Multiple large cables connect easily to the auxiliary battery
- Providing a low resistance return path for high current amplifiers
As with all of our kits, our Add-A-Battery Kits include the very best components available. Each kit is incredibly well thought out and installation is a breeze – no crimping or soldering required!
Which Kit Do You Need?
Select the kit based on the current output rating of your alternator. The 2 AWG kit is ideal for installations with alternators making up to 225A. The 1/0 AWG kit is ideal for installations with alternators making up to 300A.

The Best Cable
We use the very best cable we can get our hands on – our own! It meets full American Wire Gauge (AWG) specification, is Pure Oxygen Free Copper (OFC), and tinned for corrosion resistance. Other companies use Copper Clad Aluminum (CCA) cable in an effort to reduce cost. CCA has 30-40% greater resistance per foot than OFC, so while it may be cheaper, it also comes at the expense of performance.
Specifically, our OFC cable has the following strand count:
- 2/0 AWG Cable – 5,929 strands!
- 1/0 AWG Cable – 4,704 strands!
- 2 AWG Cable – 2,989 strands!
- 4 AWG Cable – 1,862 strands!
- 8 AWG Cable – 735 strands!
The fine-strand construction and soft jacket offer excellent flexibility, far superior to standard battery cable and better than the best welding cable!
The Best Parts
All eyelets and battery terminals are installed via our crimping press and insulated with the thickest adhesive lined heat shrink available. This super-thick adhesive-lined heat shrink tubing prevents battery acid or oxidation from entering the connection itself.
Additionally, we include a complete assortment of Grade 5 Hardware with each kit. You’ll have every single thing you need to get the job done right the first time. We guarantee it!
Step By Step Full Color Instructions
Each kit includes complete step by step instructions in full color so that your installation goes smoothly! They’re super easy to install and require only common hand tools to install them.
