BOSS Audio Systems KIT10 4 Gauge Amplifier Installation Wiring Kit – A Car Helps You Make Connections and Brings Power to Your Radio, Subwoofers Speakers
The BOSS Audio KIT10 is designed to be an entry-level, highly accessible amp install kit 4 gauge option. While BOSS kits typically utilize Copper Clad Aluminum (CCA), this kit stands out for its generous 20-foot power cable, which is four feet longer than standard 17-foot kits—a huge bonus for running cables in larger vehicles like trucks or SUVs. A notable difference is the use of a gold-plated competition AGU fuse holder. While functional, the AGU style is generally less preferred today than the ANL or Mini ANL styles for sustained high current.
Key features that stand out:
– 20 foot/ 4 gauge red power cable, high quality gold Plated competition agu fuse
– Gold plated agu in-line fuse holder
– 3 foot/ 4 gauge black ground cable
– 16 foot/ 18 gauge Blue remote turn-on wire
– 30 foot 16 gauge speaker wire
– 17 foot high performance RCA interconnect cable
– 6 foot split loom tubing, (20) 4″ Wire ties, (4) rubber grommets
Pros:
– Generous 20-foot power cable length, ideal for larger vehicles.
– Highly budget-friendly price point.
– Includes a large amount of 16-gauge speaker wire (30 feet).
Cons:
– Uses the older AGU style fuse holder, which has a lower melt temperature compared to ANL fuses.
Best for:
Installers of basic systems or budget amplifiers in large vehicles where extra cable length is needed, and maximum power draw is moderate.
Expert Opinion: This kit delivers on value and length. However, if you are planning to push over 800W, consider replacing the AGU fuse holder with a robust ANL unit for better heat dissipation and safety reliability.
Comparison Insights: Finding the Right Power Solution
When selecting the best amp install kit 4 gauge, the decision usually comes down to three main factors: material, fuse type, and completeness.
The fundamental difference lies in the wiring material. OFC (Oxygen Free Copper) provides superior power transfer and lower electrical resistance compared to CCA (Copper Clad Aluminum), which is cheaper but less efficient. For high-demand systems (over 1200W), the Skar SKAR4ANL-OFC is a clear winner because the pure copper minimizes voltage drop and heat generation.
If you opt for CCA to save money, ensure the kit is well-constructed. The RD True 4 Gauge kit is excellent because it cleverly uses Tinned OFC for the critical RCA signal cables, mitigating noise issues often found in cheaper kits.
Fuse protection is also essential for safety. ANL and Mini ANL fuses (found in Skar, DS18, and RD kits) handle higher, sustained current better than the older, competition-style AGU fuse found in the BOSS Audio KIT10. For maximum protection in high-wattage systems, look for the 100A or 120A ANL fuses.
Finally, consider accessories. Kits like the DS18 AK4 and RD True are very complete, including split loom tubing and high-quality terminals, saving you multiple trips to the hardware store.

The Best Budget Installer Kit:
For installers on a strict budget or those needing extra cable length for a truck or SUV, the BOSS Audio Systems KIT10 4 Gauge Amplifier Installation Wiring Kit provides the necessary 20 feet of power cable and a full accessory pack at the most affordable price point.
Frequently Asked Questions About Amp Install Kit 4 Gauge
Is 4 gauge wiring large enough for my amplifier?
A 4 gauge wire is a substantial thickness and is generally sufficient for most single-amplifier installations, typically supporting continuous power output up to 1200–1500 watts, provided the cable is Oxygen Free Copper (OFC) and the run is less than 20 feet. If you are using Copper Clad Aluminum (CCA) material, you should generally limit the power draw to about 1000 watts for safe and efficient power transfer.
What is the primary difference between OFC and CCA kits?
OFC (Oxygen Free Copper) kits use pure copper strands, which offer excellent electrical conductivity and flexibility, leading to significantly less resistance and a lower risk of voltage drop. CCA (Copper Clad Aluminum) kits use an aluminum core coated with a layer of copper. While much cheaper, CCA has higher resistance, meaning it gets hotter and can lead to voltage drops, slightly reducing the amplifier’s overall performance, especially at high power. OFC is always recommended for maximum audio performance and amplifier safety.
How do I choose the right fuse size for my amp install kit 4 gauge?
The fuse size (amperage rating) should always be selected based on your amplifier’s total current draw, not just the gauge of the wire. Consult your amplifier’s manual to determine the required fuse size, or add up the value of all fuses present on the amplifier itself. Never install a fuse that exceeds the maximum rating suggested by the amplifier manufacturer, as this compromises safety.
What does the remote turn-on wire do in an amp install kit 4 gauge?
The remote turn-on wire (usually a thin blue or black wire, typically 18 gauge) carries a low-current signal (usually 12V) from your head unit or ignition switch back to the amplifier. This signal tells the amplifier when to turn on and off, ensuring the amp doesn’t drain your vehicle battery when the car is off.
Is flexibility important when choosing a power wire jacket?
Yes, extreme flexibility is highly important. Power cables often need to be routed through tight factory grommets, under carpets, and along door sills. Kits that advertise “Max-Flex” or “Super Flex” (like the Skar and DS18 options) use soft, pliable PVC jackets and often have a higher strand count, making the installation process significantly easier and reducing the chance of damaging the wiring insulation.
Should I prioritize an ANL or an AGU fuse holder?
In modern installations, you should prioritize the ANL (Automotive Normal Load) fuse holder (or the Mini ANL style). ANL fuses are designed for high amperage applications and dissipate heat more effectively than the older, glass-tube AGU (Amplifier Glass Tube) fuses. The AGU style, such as that found in the BOSS kit, is often best reserved for lower-power or less demanding systems.
