ELECTRICAL & INSTALLATION

At this power level, upgraded electrical support is required for reliable full-output operation. Use properly sized OFC power and ground wiring, solid low-resistance grounds, correct fusing, and enough charging and battery reserve to keep voltage stable under load.

Warranty coverage does not include operation below 11V. If you are running the 5000.2 hard at 1 ohm per channel, the charging system and reserve capacity need to be designed around that demand. A Big 3 upgrade and high-output charging are strongly recommended.

FREQUENTLY ASKED QUESTIONS

Is the 5000.2 really 1-ohm stable per channel?

Yes. The standard 1-year manufacturer defect warranty covers operation down to 1 ohm per channel when Ruthless warranty conditions are met.

How much power does it actually make?

The factory rating is 2,500W × 2 at 1 ohm. Certified dyno testing measured 5,477W combined at 1 ohm, with dynamic testing reaching 6,094W combined under the test conditions shown above.

Can I use it for mids and highs?

Yes. The 5000.2 is designed as a high-output 2-channel amplifier and can be used for demanding stereo speaker systems as long as the drivers, crossover strategy, gain structure, and final impedance are appropriate.

FULL SPECIFICATIONS

ELECTRICAL & INSTALLATION

The 10000.1 requires a serious electrical system. For full-output use, plan around high-output charging, a complete Big 3 upgrade, substantial AGM or lithium reserve, short low-resistance grounds, and properly sized OFC wiring. The amplifier uses three positive power runs; for warranty compliance, each positive run must be protected by a fuse rated at no more than 350A.

Do not let system voltage fall below 11V. Low-voltage operation is not covered under warranty. The electrical system should be built with enough capacity and reserve to keep voltage stable under the intended load.

For 0.5-ohm operation, verify the final impedance of the complete subwoofer and voice-coil configuration before connecting the amplifier. Wiring below the covered load is not warrantable.

FREQUENTLY ASKED QUESTIONS

Is the 10000.1 warrantied at 0.5 ohm?

Yes. The standard 1-year manufacturer defect warranty covers operation down to 0.5 ohm when all installation and operating requirements are met.

Why does the 10000.1 use triple power and grounds?

At this output level, current delivery is critical. Multiple 1/0 AWG connections reduce bottlenecks and distribute current through several large conductors instead of relying on a single feed.

Can I run it on stock electrical?

No if the goal is anything close to full rated output. This amplifier should be treated as part of a complete high-output electrical system, not as a stand-alone upgrade.

What is the difference between Black and Red?

Finish only. Both color options use the same Ruthless 10000.1 amplifier platform and performance specifications.

What can void warranty coverage?

Warranty does not cover vibration damage, wire or debris inside the amplifier, wiring below the covered impedance, external RCA damage, excessive clipping, or operation below 11V. Full warranty terms apply.

EXTENDED WARRANTY

No – Standard Warranty (1 Year)
Includes the standard 1-year manufacturer defect warranty, including covered operation down to 0.5 ohm when all warranty requirements are met.

Yes – Extended Warranty (2 Years Total)
Adds 1 additional year of manufacturer defect warranty coverage for 2 years total.

AMPLIFIER & WIRING RECOMMENDATIONS

Use quality OFC power and ground wiring with proper fusing and a short, low-resistance ground. A correctly installed 4 AWG kit is a strong choice for many 800.4 Micro installations. Keep RCA and signal wiring separated from high-current power runs.

For bridged operation, use a minimum 4-ohm bridged load. Standard warranty coverage is down to 2 ohms per channel in stereo operation when all warranty requirements are met.

Give the heatsink room to breathe in enclosed installations. Operation below 11V, excessive clipping, and wiring below the covered impedance are not covered under warranty.

FREQUENTLY ASKED QUESTIONS

Is the 800.4 Micro warrantied at 2 ohms per channel?

Yes. The standard 1-year manufacturer defect warranty covers operation down to 2 ohms per channel when Ruthless warranty requirements are met.

Can I bridge the 800.4 Micro?

Yes. Channels can be bridged in pairs for a 2-channel configuration. Keep the bridged load at 4 ohms or higher.

How is it different from the full-size 800.4?

The Micro version is built around packaging efficiency: a much smaller chassis with 200W × 4 at 2 ohms. The full-size 800.4 produces 220W × 4 and adds the larger Korean platform, Tiffany-style RCA inputs, clip-light function, and wider x10 crossover controls.

Is it good for a stealth install?

Yes. At only 9.25 inches long and 2.2 inches tall, it can fit in locations where a traditional full-size amplifier cannot.

What can void warranty coverage?

Warranty does not cover vibration damage, wire or debris inside the amplifier, wiring below the covered impedance, external RCA damage, excessive clipping, or operation below 11V. Full warranty terms apply.
