TOPSTRONGGEAR 4 Gauge 25ft Black and 25ft Red Power/Ground Wire 4 True AWG Power Wire-True Spec and Soft Touch Cable (Black&Red)
Grade A- CCA Power Wire-Our CCA contains 30% copper,which is closer to OFC and more cost-effective.
This 25-foot cable comes in two colors, red and black. It's made of 4-gauge wire, which is thicker than most 25-foot cables, and it's soft to the touch, so it's less likely to tangle. The wire is CCA (copper clad aluminum), which presents a good conductor for power transfer. The insulation is thicker than most wires, so it's less likely to chafe against your aircraft. The wire is shielded, so you won't have to worry about interference. This cable is less expensive than the 10-gauge wire we recommended in our budget pick, and it's slightly thicker, so it's worth the extra money if you don't need as much wire.

ROCKRIX 4 Gauge 25ft Black and 25ft RED Audio Car Power Ground Soft Touch Wire Cable
Perfect for Radio, Home Theatre, Automotive, Stereo, Robotics and R/C applications
This cable is a home run. It delivers the precise amount of power that your car needs, with no hint of distortion. It's flexible, durable, and looks great. The wire is thick enough to resist arcing, and it's slim enough that it won't get in the way. It's also incredibly durable, with a robust metal connector that resists wear and tear. The cable is 25 feet long (about 8 feet longer than our previous pick), and it has a 4-gauge internal wire. The 4-gauge wire provides enough power transfer for just about any car, especially older cars, and the 25-foot cable length provides enough slack to accommodate most installs. It's particularly great for people with vehicles with older wiring that hasn't had much power transferred over the years. The cable has a solid metal connector, the rubber jacket is flexible, and the cable is 25 feet long, making it perfect for most cars.

InstallGear 1/0 Gauge Red 25ft Power/Ground True Wire Spec and Soft Touch Cable
SOFT TOUCH JACKET - The jacket on our cable is designed with the installer in mind. The flexibility of this jacket allows for easy routing and has a low memory.
The 1/0 gauge wire from InstallGear is slightly thicker than our former pick, the Monoprice 25-foot 1/0 gauge wire, and it's also more flexible and kink-resistant. The wire from this pick is coated with heavy PVC jacketing, which makes it easier to work with. The wire is easy to work with and crimps neatly. The wire colors make it easy to distinguish between the power and grounds.

ROCKRIX 8 Gauge 25ft Black and 25ft RED Audio Car Power Ground Soft Touch Wire Cable Set
Perfect for Radio, Home Theatre, Automotive, Stereo, Robotics and R/C applications
The ROCKRIX 8 Gauge 25ft Black and 25ft RED Car Audio Power Ground Soft Touch Wire Cable Set is a terrific choice for setting up a car audio system or for upgrading your vehicle's sound system. While it's more expensive than some similar cables, it's worth the money. The cable is long enough for most in-car applications, and the plugs on both ends are sturdy enough to hold up to regular use. The wire is thin enough (about 3.5mm in diameter) that it's barely noticeable, and it's flexible enough that it bends easily to fit any space. In fact, the more flexible the cable, the easier it is to install. The soft PVC jacket makes this cable a great choice for both indoor and outdoor use. It allows for greater flexibility, and the cable is waterproof, so there's no need to worry about it getting wet or damaged. The cable comes with two non-polarized plugs on both ends, so if you want to use the cable to connect to a stereo or other device with a polarized plug, you'll need to purchase an adapter. The cables are color coded, so it's easy to tell which wire is which. The cable is too thin to be suitable for heavy-duty power applications, but it's perfect for use with home audio equipment.

SoundBox Connected 0 Gauge Amplifier Red/Black Power/Ground Wire Set
Wire is Set to International Wire Gauge Standards (NOT AWG)
The SoundBox Connected 0 Gauge Red/Black Amplifier Power/Ground Wire Set offers plenty of value and flexibility, particularly for the amateur musician or DJ. These 50-foot long cables come with two 1/0 gauge power/ground cables, one red and one black. These cables are ultraflexible and heat tested, so they're less likely to break during performance. The wire jacket is CCA (copper clad aluminum), which is more durable than standard PVC wire and is more resistant to corrosion. These cables are also precut and prestripped, so they're easy to install. The connectors on both cables are durable, and the hooks that hold the cables together are sturdy. These cables are designed to work with Soundbox Connected 0 Gauge Fuse Holders, which are listed separately.

InstallGear 8 Gauge 25ft Black and 25ft Red Wire Power/Ground True Spec and Soft Touch Cable
SOFT TOUCH JACKET - The jacket on our cable is designed with the installer in mind. The flexibility of this jacket allows for easy routing and has a low memory.
InstallGear's 25ft 8 gauge power/ground wire is our favorite budget option. It's flexible, durable, and easy to install, and it comes in 25ft lengths, which means you won't have to stretch it, and it won't kink up. The 25ft red wire is, well, red, and is easier to see than the 25ft black wire. The wires are also the two cheapest options we tested, and both are 8 gauge. The red and black wires are each 25ft long, and each costs just $13.99. If you're still wondering whether it's worth spending the extra money for the 16 gauge wire, our theory is that the difference in wire quality is relatively small, and in most cases, it will affect sound quality and performance only slightly. The 16 gauge wire is thicker, and it will provide slightly better performance, but it's not cheap, either, costing $25 for 25ft.

SoundBox Connected 4 Gauge Black Amplifier Amp Wire Power/Ground 100 Feet Superflex Cable 100' Spool
Grade A- CCA Power Wire

SoundBox 0 Gauge Blue Amplifier Wire Power/Ground 1/0 Ga Amp Cable
Wire is Set to International Wire Gauge Standards (NOT AWG)
The SoundBox 0 Gauge Amp Cable is pre-crimped, pre-wired, and pre-stripped with a blue jacket. This 25-foot cable runs directly from the battery to your car amplifier. The amp cable is 1/0 gauge, and the gauge size determines how much power the cable can safely carry. The 1/0 gauge cable can carry up to 150 watts of power, so it's enough to run your amplifier and speakers at the same time. The amp cable is long enough to run from the dashboard to the driver's side of the car, and the jacket is flexible, so it's easy to run the cable through your dash or under the hood. The amp cable is 25 feet long, which is long enough for most cases. The amplifier and speakers will need to be placed far enough from the amplifier to avoid interference, and the amp cable will usually need to be connected to your car's power/ground wire, which will either be connected to the battery or to the alternator. The amp cable is long enough for most applications, but keep in mind that the amp cable can only carry so much power, so you may need to connect multiple amp cables together to reach your car's power/ground wire. The SoundBox 1/0 Gauge Amp Cable is a good option for those on a budget, and the cable is flexible, so it's easy to work with.

The cable is not designed to be hooked up to amplifiers, but it's compatible with most amps.
