Soundstream TXP1.18000D TXP1‑18000D | 18000 Watt 1Ω Stable Monoblock Class D Amp

For competitors who don't settle for average, Soundstream presents the Tarantula XTREME POWER Series — the ultimate SPL-class amplifier built for those who demand unrelenting output from their audio setup. The TXP1‑18000D is a monoblock Class D amplifier with a staggering 18,000 watts peak and 7,000 watts RMS @1 ohm, crafted to support serious competition-grade subwoofer systems. With a compact footprint and heavy-duty build, it fits performance into tight installs without compromising raw power delivery.

At the core of the TXP1‑18000D is a silicon steel alloy transformer, designed to outperform traditional toroidal cores by delivering higher current more efficiently. This translates into stronger sub-bass output with less strain on your vehicle's electrical system. Smart protection features include direct short, thermal, and overload protection; a dash-mounted gain control knob; dual cooling fans; and LED circuit board lighting. Variable 12 dB/oct crossovers (high-pass, low-pass, and subsonic filters) and 0 dB to 12 dB bass boost at 50 Hz allow for tailored subwoofer tuning. Its 1 ohm stable output ensures steady power to demanding subwoofer setups.

Built for competitive installs, this amplifier features military-grade PCB construction and high-level and low-level RCA inputs (200 mV–6 V). Whether you're entering SPL lanes or just want to shake the block with low-end fury, the TXP1‑18000D delivers raw output paired with smart, heat-conscious design.
