Blurred Vision Audio Diamond Series DS-18K.1D (18000RMS) 1 Ohm (Open Box)

⚡ The Blurred Vision Audio Diamond Series DS-18K.1D is a monoblock (single-channel) Class D amplifier, designed for extremely high-power applications. It’s capable of delivering up to 18,000+watts RMS at 1 ohm, which is incredibly high and clearly aimed at competition-level SPL (sound pressure level) setups rather than everyday listening. The amplifier uses compact “Small Footprint Technology”, making it easier to install in tight spaces despite its massive power output.

Features

Full Range EQ: Separate adjustments for Bass, Mid Bass, Mid High, plus Level, HPF, and LPF.

Voltage display & clipping indicators: Useful for monitoring performance.

Dual Inputs & Quad Fuse Block: Supports flexible wiring setups.

Fans & compact design: Efficient cooling in a small chassis.

Applications: Can drive subs, woofers, drivers, and even tweeters if needed.

Installation Tips

1. Turn off amplifier before connecting or disconnecting cables to prevent damage.

2. Avoid noise interference: Keep power and signal wires away from ignition and starter circuits.

3. Use 100% copper wires and high-quality connectors to maintain sound fidelity.

4. Fuse protection: Place the fuse within 12 inches of the battery.

5. Load caution: Designed for music speaker loads; resistive load tests are not recommended.

Pros

Extremely high RMS power in a compact design.

Efficient Class D operation (85–95%).

Full frequency response allows multi-use (sub + full range).

Robust protection features: voltage display, clipping indicators, and built-in cooling.

Comes with all wiring essentials: dual inputs, fuse block, fuses, and bass knob.

Things to Watch

Insane power: This is 18kW RMS at 1Ω—most car electrical systems cannot safely supply this without serious upgrades (multiple batteries, high-output alternator, thick wiring).

Realistic power delivery: Manufacturers often rate Class D amps at peak RMS; real-world output may be lower, especially at higher frequencies.

Installation difficulty: Requires expertise in SPL wiring, high-current fusing, and careful heat management.

Best Use Case

This amplifier is built for car audio competitions with multiple high-power subwoofers. It’s overkill for casual listening or normal vehicles without major electrical system upgrades. Ideal setups might include:

Professional competition vehicles with high-capacity batteries and alternators.

Systems where compact space is needed but extreme power is desired.

Warranty 

 Running this amplifier below recommend ratings will likely blow mosfets and burn the board. No warranty will be given when the board is burnt NO EXCEPTIONS. 

Product defect Warranty

Period is 1 year from the date of purchase. If you burn the amplifier’s mosfet, or burn the amplifiers board we know this is from either improper voltage, improper wiring, or playing while clipping which can result in burning the PCB board which is not covered under warranty. NO EXCEPTIONS.
