Nemesis Audio NA-K7500D 7500W @ 1-Ohm Class D 1-Channel Monoblock Car Amplifier Made In Korea Team Series

The Nemesis Audio NA-K7500D is a 1-channel Class D monoblock amplifier built for extreme subwoofer duty, part of the Korea-made Team Series, ready to unleash serious bass with up to 7,500W RMS at 1 ohm.

• 1-Ohm RMS Power: 7,500W x 1 — can deliver peak single-channel output into a 1-ohm load, ideal for very high‑power subwoofers and aggressive bass when wiring single subs for maximum excursion.
• 2-Ohm RMS Power: 4,200W x 1 — strong performance at a slightly higher load, suitable for systems using low-impedance subs with optimized efficiency.
• 4-Ohm RMS Power: 2,100W x 1 — provides solid output for subs wired to a 4-ohm load, balancing power and heat for typical setups.
• 2-Ohm RMS Strappable Power: 15,000W x 1 — when paired or bridged in a 2-ohm configuration, enables substantially higher total system power for multi-sub or high‑demand installations.
• Frequency Response: 10Hz–250Hz — covers deep bass fundamentals up into upper-bass regions, giving subs room to reproduce very low tones while staying controlled at higher bass frequencies.
• Signal to Noise Ratio: 95dB — lower audible noise from the amp, helping bass signals remain clean at high output levels.
• Damping Factor: 400dB — indicates strong control of speaker motion, contributing to tighter bass response under demanding playback.
• Efficiency (4-Ohm 100Hz): 90% — high efficiency reduces heat and improves power usage during prolonged bass bursts.
• Input Sensitivity: 6V–0.2V — defines the voltage range needed from the head unit to reach full output, guiding compatible source equipment choices.
• Subsonic Filter: 10Hz–50Hz @ 24dB/Oct — filters out ultra-low frequencies that can stress subs, protecting components and improving bass clarity.
• Bass Boost: 0–9dB @ 45Hz — user-adjustable boost to tailor bass emphasis to vehicle acoustics and personal taste.
• Low Pass Filter: 35Hz–250Hz @ 24dB — limits high-frequency content reaching the woofer, helping control bass transient response and prevent woofer overexcursion.
• Strappable Connection: 0 Gauge Power & Ground Input — requires heavy-gauge wiring for safe, high-current operation in performance installations.
• Working Voltage: 10V–16V — designed to operate within typical automotive electrical systems, accommodating normal voltage swings in vehicles.
• Made In: Korea — part of the premium Team Series lineage from Nemesis Audio.

Benefits: The NA-K7500D is engineered for premium, high‑power subwoofer systems where extreme output and precise bass control are required. Its 1-ohm capability and 2-ohm strapped option let you scale for a single ultra‑low‑impedance sub or a multi-sub setup, while the integrated subsonic and low‑pass filtering, adjustable bass boost, and high damping factor deliver clean, controlled bass with reduced unwanted noise and distortion. A 0‑gauge power/ground requirement and 10–16V operating range align with typical performance builds, making this amplifier a focused choice for serious bass enthusiasts seeking maximum wattage in a compact, Korea-built package.
