Product Overview
Bring substantial mono-channel power to a high-output car audio system with the Ruthless Audio 4500.1 monoblock amplifier. It delivers up to 4,500W RMS at 1Ω and is rated stable down to 0.5Ω, with electrical upgrades required for 0.5Ω operation.
Key Features & Benefits
- Three RMS power ratings: Choose the load that suits your system, with ratings listed at 1Ω, 2Ω, and 4Ω at 14.4V.
- Strappable design: Pair two 4500.1 amplifiers in a 1Ω strapped configuration for a dual-amplifier build.
- 1/0 AWG power inputs: Full-size power and ground terminals support the amplifier’s high-current installation requirements.
- Tiffany-style locking RCA inputs: The locking connections help keep RCA cables secured at the amplifier.
- Low-frequency controls: A 10Hz–250Hz frequency response and 0°–180° phase control support subwoofer integration.
- Compact height, substantial footprint: Check the listed dimensions to plan space for this 25-1/8-inch-long amplifier.

Why Choose This Product?
The 4500.1 offers distinct RMS ratings across 1Ω, 2Ω, and 4Ω loads, helping you compare amplifier output with your planned subwoofer load. Its strappable design also supports a two-amplifier configuration, with the pair operating at 1Ω when strapped.
For subwoofer pairing, the product details recommend high-power competition subwoofers rated for 2,000W RMS or more. They also describe dual 2Ω subwoofers wired in parallel for a 1Ω load, or dual 1Ω subs in parallel for a 0.5Ω load.
Installation & Compatibility Notes
This amplifier has a high current demand. The installation guidance recommends a high-output alternator rated at 200A or greater, a Big 3 wiring upgrade using 1/0 AWG cable, and sufficient AGM or lithium battery reserve. Use a dedicated 1/0 AWG power and ground run from the battery to the amplifier.
Running at 0.5Ω without the recommended electrical upgrades risks voltage sag and thermal shutdown, and may void 0.5Ω warranty coverage. Plan mounting space around the listed dimensions. The product details also recommend using a DSP or active crossover to set low-pass and subsonic filters before the amplifier input.
Frequently Asked Questions
