Comparison Insights: Choosing the Right Kicker Kit
When selecting a wiring kit, the difference between the Kicker models often comes down to what components are included.
The Kicker Complete Kits (CK4 and 46CK4) are designed for first-time installers or those who want guaranteed compatibility. They provide everything, including the critical RCA interconnects and speaker wire. If you are building a system from scratch, a complete kit simplifies the process.
In contrast, the Power Kits (PK4 and PKD4) exclude the signal and speaker wire. This is crucial if you already have high-end, specialized RCA cables or if you are only installing an amplifier for a subwoofer. They save you money by focusing solely on current delivery, which is perfect for dedicated sub installs.
If you are running substantial power, always prioritize the OFC (Oxygen-Free Copper) found in the Kicker kits over the CCA (Copper Clad Aluminum) of budget options like Skar Audio. While CCA is cheaper, the reduced conductivity of aluminum requires careful consideration of the wire’s actual copper content and resistance, especially over longer vehicle runs.

Common Questions About Kicker 4 Gauge Amp Kit
Is 4 gauge wire necessary for all aftermarket amplifiers?
Four gauge wire is highly recommended for amplifiers drawing significant power, typically systems rated between 600 watts and 1,000 watts RMS. If your amplifier is rated much lower (e.g., under 400 watts RMS), 8 gauge wire might suffice. However, running a kicker 4 gauge amp kit offers better headroom and future-proofing, ensuring minimal voltage drop even when the amplifier is running at peak capacity.
What is the difference between OFC and CCA wire in these kits?
OFC (Oxygen-Free Copper) wire, used in premium Kicker kits, is made of pure copper, offering the lowest resistance and highest conductivity. CCA (Copper Clad Aluminum) wire, used in budget kits, uses an aluminum core coated with a thin layer of copper. OFC is superior for high-power applications because it transmits current more efficiently and generates less heat.
How do I properly fuse my kicker 4 gauge amp kit?
The fuse holder must be installed within 18 inches of the battery terminal. Kicker typically provides an AFS or ANL fuse holder rated appropriately (often 100A) for the wire gauge and maximum recommended wattage. Never install a fuse rated higher than what your amplifier or the wire itself can safely handle.
Can I run a kicker 4 gauge amp kit under the carpet?
Yes, most people run power wire under the carpet or along the door sills (kick panels). It is crucial, however, to keep the power cable separated from the RCA signal cables to prevent noise and engine whine from interfering with your audio signal. Run power down one side of the vehicle and signal down the other.
What does “Full Spec” wire mean for the Kicker kits?
“Full Spec” (or “True Spec”) wire means that the actual cross-sectional area of the conductive material meets the official American Wire Gauge (AWG) standard for 4 gauge wire. Some cheaper kits may use overly thick insulation to make a smaller gauge wire appear larger. Kicker’s Full Spec wire guarantees the necessary copper content for effective power delivery.
Do I need to buy additional terminals for the wiring kit?
Typically, no. The kicker 4 gauge amp kit is designed to be complete and usually includes the ring terminal needed for the battery connection, the ground terminal, and often spade or butt connectors for the remote wire and speaker wire connections, depending on whether it is a “Complete” or “Power Only” kit.
