Sky High Car Audio, 1/0 AWG, 350A Big 3 Upgrade Kit
The one-step “Big 3” upgrade kit
If your aftermarket audio system is putting a strain on the rest of your car’s electronics, you might want to upgrade your factory wiring. Rated to 350 amps, this “Big Three” electrical upgrade package will boost your electrical system’s performance by allowing the maximum current to flow easily from your alternator, greatly improving the system’s ground connection to your vehicle’s chassis.
Sky High Car Audio kit includes heavy-duty 1/0-gauge oxygen-free copper cables that replace your vehicle’s battery ground-to-chassis wire, the chassis-to-engine block wire, and the alternator charge output wire. Another bonus is that the ring terminals are already crimped to the wires, so you won’t have to replace the stock grounds unless you want to improve them or double up.
Please note, each end of the cable has a pre-installed copper ring terminal and heatshrink.
Step 1 Connect one of the two ground cables between the battery
and a solid chassis ground. This cable can either replace the
existing ground, or can be used in addition to the existing ground
Step 2 Connect the second of the two ground cables between the
alternator ground stud and the chassis. If a ground stud is not
available, using one of the rear alternator mounting bolts will also
work the same.
Step 3 Connect the remaining power cable between the alternator
and the battery, and keep clear of moving engine components and
extreme heat items like the radiator, valve covers and exhaust
Step 4 Safely tie up and secure each individual cable with the
zip ties and cable clamps (Not included)
