Comparison and Practical Buying Insights
When you evaluate a potential kicker amp wiring kit, the decision often boils down to power needs and integration requirements.
The most crucial factor is gauge size vs. wattage. If you run over 1000 watts RMS, you absolutely need the heavy-duty 1/0 AWG dual kit (46PKD1) to avoid critical voltage drop and amp overheating. For most single amplifiers pushing 400-800 watts, the 4-AWG kits (46CK4 or CK4) offer the best balance of flexibility and current capacity. The 8-AWG kit (46CK8) is only appropriate for very small systems, typically under 400 watts. Always use the thickest wire you can reasonably install, as copper quality and wire size are non-negotiable for amplifier performance.
If you are replacing your factory head unit with an aftermarket unit, you only need the power/ground/signal kits (46CK4, 46CK8, etc.). However, if you are keeping your factory radio, the 46KISLOC2 is absolutely essential for converting speaker signals into RCA outputs and providing a clean remote turn-on signal. You cannot properly integrate a modern amplifier into a factory system without a quality Line Output Converter (LOC).
Look closely at the Hyper-Flex cabling found in all these Kicker kits. This high-strand-count, flexible wire makes pulling the cable from the battery compartment through the firewall incredibly less frustrating than working with stiff, cheap wire kits.

Selecting the right kicker amp wiring kit depends entirely on the size and complexity of your audio system.
The Power Enthusiast’s Choice: For those running complex, high-current systems (1000W+ RMS or dual amps), the Kicker 46PKD1 1/0AWG Dual Amplifier Power Kit is the only safe and reliable option. It manages high current flow and distribution flawlessly.
The Balanced Performer: For the majority of users installing a quality single amplifier (subwoofer or speaker amp) with excellent components, the Kicker 46CK4 K-Series Complete 4-AWG Amplifier Connection Kit provides the best combination of quality materials, true gauge size, and premium signal delivery (K-Series RCAs).
The System Integrator’s Necessity: Regardless of the power kit you choose, if you are tapping into a factory stereo, the Kicker 46KISLOC2 K-Series Stereo Line-Output Converter must be part of your installation plan. It solves critical signal and turn-on issues that plague factory integration.
Frequently Asked Questions About Kicker Amp Wiring Kit
What is “full spec wire,” and why does Kicker emphasize it?
“Full spec wire,” often referred to as “true gauge” wire, means the cable actually contains the amount of copper conductors required to meet the stated AWG size standard. Many budget kicker amp wiring kit alternatives use Copper-Clad Aluminum (CCA) or use a thicker jacket to mimic a larger gauge, which leads to voltage drop, overheating, and poor amplifier performance. Kicker’s full spec Hyper-Flex wire ensures maximum power delivery.
How do I choose the correct gauge size for my amplifier installation?
The correct wire gauge is determined by two main factors: the total power (RMS wattage) of your amplifier and the distance the wire must travel. For runs under 15 feet: use 8-gauge for systems under 400W, 4-gauge for 400W to 1000W, and 1/0-gauge for anything over 1000W. If your wire run is significantly longer (like in a truck or SUV), consider stepping up one gauge size to compensate for resistance.
Is the remote turn-on wire provided in the Kicker kits automatically functional?
The full power wiring kits (like the 46CK4 or CK8) include a thin blue remote turn-on wire. This wire is only functional if you are installing an aftermarket head unit that provides a 12V remote signal. If you are keeping your factory stereo, you must use a specialized component like the Kicker 46KISLOC2 to generate the necessary remote turn-on voltage signal.
What is the advantage of Hyper-Flex cable over standard cable?
Hyper-Flex is known for its high strand count, meaning the cable is composed of many fine copper strands instead of fewer, thicker ones. This high strand count makes the wire extremely flexible and easy to bend around corners and through tight openings in the vehicle’s chassis, significantly speeding up the amp installation process while maintaining high current capacity.
Can I run two amplifiers off a single 4-gauge kicker amp wiring kit?
While technically possible with a separate distribution block, it is highly discouraged unless the combined RMS wattage of both amplifiers is well under the 4-gauge limit (around 800W RMS). If you are running multiple amplifiers, especially high-power ones, you should use a dedicated solution like the 1/0AWG Dual Amplifier Power Kit (46PKD1) to ensure safety and prevent major voltage sag.
Are Kicker amp wiring kits safe for high-temperature environments?
Yes. Kicker ensures its Hyper-Flex cables have durable, heat-resistant jacketing designed for use in engine bay and interior environments. The kits also include robust AFS or ANL fuse holders, which are essential safety components that protect the wiring and your vehicle’s electrical system from short circuits or major current spikes.
