Tchernov 0 AWG Power Cable Review: The Main Feed for High-Current Systems
Updated: Oct 6
The Tchernov 0 AWG power cable is the thickest size in Tchernov Cable's Standard DC Power line, a single-conductor cable for high-current 12–24 V DC wiring. Its multi-stranded conductor measures 53.50 mm² and sits inside a 17 mm NPVC jacket. The 2026 Indian catalogue lists it at an MRP of ₹1,59,990 for a bulk quantity of unstated length. It's the main feed for a large multi-amplifier system, a big subwoofer monoblock or a Big 3 charging upgrade, not the cable for one compact amplifier. You can see the listing on our Tchernov Standard DC Power 0 AWG product page.
At a glance
About two and a half times the conductor area of the 4 AWG version, so far less voltage is lost over a long battery-to-boot run.
At 17 mm across, it needs 0 AWG lugs, a large firewall grommet and careful routing.
Owner reviews are scarce: the only discussion we found covers the 4 AWG and 8 AWG sizes and is about sizing, not build quality.
The MRP covers a bulk length the catalogue doesn't state, so confirm it with us before ordering.

Figures come from Tchernov Cable's Standard DC Power page and the 2026 Indian catalogue. The catalogue gives no current rating, no jacket temperature rating and no conductor metallurgy beyond the BRC label, and it doesn't say how long the bulk quantity is. Tchernov is a Russian brand, but this cable's listed country of origin is Belarus.
Where a 0 AWG main feed belongs
In a car audio system, a cable this size carries the combined current of every amplifier from the battery to the back of the car. It runs from a fuse beside the battery to a fused distribution block near the amplifiers, with smaller branches to each amplifier and an equally heavy ground lead from the block to bare chassis metal.
To judge whether you need it, estimate the current: divide an amplifier's total rated RMS output by its efficiency (commonly around 80% for Class D at full power, 50–60% for Class AB), then by the supply voltage. JL Audio's RD1500/1 monoblock makes 1,500 W RMS into 2 Ω, which works out at roughly 140 A, close to the 150 A fuse JL specifies. Add a JL Audio VX600/6i for the speakers, fused at 50 A, and combined peaks approach 200 A. Music averages far less, but deep bass notes come close.
Voltage drop, heat and run length
Voltage lost along a cable is current multiplied by resistance. A copper conductor of 53.50 mm² measures roughly 0.32 milliohm per metre at room temperature, so a 5.5 m run, typical of battery-to-boot routing in a large SUV, loses about 0.35 V at 200 A. The same current through 4 AWG would lose nearly 0.9 V and turn around 175 W into heat.
That matters because amplifier output follows supply voltage: JL rates the RD1500/1 at 1,500 W into 2 Ω at 14.4 V but 1,200 W at 12.5 V. At idle in city traffic, with the AC compressor, blower and radiator fans running, system voltage can sit well below the 14 V-plus you see on the highway. A thick feed can't fix that, but it stops the cable adding to it. Heat counts too: copper's resistance rises about 0.4% per degree Celsius, so a boot at 50 °C in May adds roughly a tenth to those losses.
The Big 3 upgrade
The Big 3 replaces or supplements three factory cables: alternator positive to battery positive, battery negative to the body, and engine block to the body. Heavier cables cut resistance in the charging path, so more of the alternator's output reaches the battery and amplifiers. 0 AWG is a common choice because it comfortably exceeds the factory leads in most cars. The upgrade doesn't make the alternator produce more current; it wastes less of what it already makes.
Two cautions apply to modern cars. Many have a battery sensor on the negative terminal that the engine computer uses to manage charging; every ground path must keep passing through it, so new grounds attach on its chassis side, never straight to the battery post. The new alternator lead also needs its own fuse near the battery, rated above the alternator's maximum output. Ask us to look at your charging system first, and we'll tell you whether the Big 3 is worth doing on your car.
What owners and reviewers say about the Tchernov 0 AWG power cable
Independent reviews of this exact size are scarce: when we checked in October 2026, we found none we could verify. The nearest thing is a January 2017 thread on the Russian car-audio forum Auto-HiFi.ru, which covers the 8 AWG and 4 AWG sizes of the same line rather than this 0 AWG cable. A buyer whose amplifiers drew roughly 180 A in total asked which of those two would do; a member advised going up to 2 AWG instead, and the buyer found the heavier gauge expensive for his wiring budget. It's sizing advice, and it says nothing about how the cable is built.
Beyond that, the only verifiable material is Tchernov's own promotional description: suitable for any mobile set-up, four common sizes, two colours, and NPVC insulation it says is widely used in the medical industry. If you've run this cable in your car, we'd like to hear how it held up.
0 AWG, 4 AWG or 8 AWG: choosing within the Standard line
The Tchernov 4 AWG power cable (21.50 mm², 10.2 mm, on spools) is the right feed for one mid-sized amplifier. The Tchernov 8 AWG power cable (8.50 mm², 7.4 mm) suits small amplifiers and branch runs from a distribution block. The 0 AWG conductor has more than six times the area of the 8 AWG, and that metal is what you pay for in weight and routing effort.
Prices are harder to compare than they look. The catalogue lists ₹1,59,990 for the 0 AWG bulk quantity, ₹2,19,990 for a 4 AWG spool and ₹1,49,990 for an 8 AWG spool, but states no lengths, so the figures say nothing about cost per metre. A 2 AWG size (35.00 mm², 12.5 mm) exists in the line but has no Indian MRP. The Standard series also includes Standard 2.0 speaker wire and the Standard Coaxial IC RCA interconnect.
Who should buy it, and who shouldn't
It makes sense if your amplifiers' fuse ratings add up to well over 100 A, your route is long, as in a seven-seater SUV, or you're doing the Big 3 alongside a high-power build. It's also a sensible main feed if you'll add amplifiers later, since pulling a second cable through the firewall is more work than buying headroom once.
Skip it if you run one amplifier fused at 50–80 A: 4 AWG handles that with far easier routing. And if your headlamps already dim on bass notes at idle with the AC on, a thicker cable won't cure it. The battery or alternator is the limit there.
Installation notes for Indian cars
Fit the main fuse or circuit breaker within about 45 cm (18 inches) of the battery's positive terminal, sized to protect the cable rather than to match the amplifiers, and fuse each branch separately at the distribution block. Zapco's manual for its Z-CB100F capacitor bank gives the same 18-inch rule.
Use 0 AWG lugs and a proper crimping tool; a lug squeezed shut with pliers loosens over broken roads and runs hot. In set-screw terminals, a ferrule stops the fine strands splaying. A 17 mm cable resists tight bends, so plan the route first: a large grommet through the firewall, clear of exhaust heat, seat rails and sharp edges, and down the opposite side of the car from the RCA cables to limit noise pickup. Scrape the ground point to bare metal and seal it against monsoon rust. VA3 Car Studio in Ghaziabad installs main feeds, distribution blocks and the Big 3.
Price and where to buy
The 2026 Indian catalogue gives the Tchernov 0 AWG power cable an MRP of ₹1,59,990, supplied in bulk, without stating the length. Ask us to confirm it, and tell us your car and amplifiers so we can work out how many metres your route needs. VA3 Car Studio often sells below MRP; check the current offer on our Tchernov 0 AWG cable listing. It's genuine Tchernov Cable, distributed in India by Supreme Audiotek.
The bottom line
This cable is for systems that genuinely draw big current: large monoblocks, several amplifiers on one feed, or a Big 3 upgrade. Its 53.50 mm² conductor keeps losses small even on long SUV runs. Owner feedback is thin and the bulk length is unstated, so confirm that before buying. For a single mid-power amplifier, the 4 AWG version is the smarter spend.
Tchernov 0 AWG power cable FAQ
Do I need the Tchernov 0 AWG power cable for a single amplifier?
Usually not. A single amplifier fused at 50–80 A runs well on 4 AWG over a typical car-length route. 0 AWG earns its place once combined draw passes roughly 120 A, or when the route is unusually long.
Can I use 0 AWG cable for the Big 3 upgrade?
Yes, it is a common choice for all three Big 3 runs because it exceeds most factory charging cables. Fuse the new alternator lead near the battery, and if your car has a battery sensor on the negative terminal, keep every ground path running through it.
How much cable does the MRP cover?
The 2026 Indian catalogue doesn't state the length behind the ₹1,59,990 MRP. Ask VA3 Car Studio to confirm it before ordering, and measure your intended route with a piece of string first.
