Soundstream TXP1-18000D Tarantula XP 7,000W RMS Monoblock Amplifier

Product Overview

The Soundstream TXP1-18000D Tarantula Xtreme Power amplifier uses a full-bridge Class D design to drive a demanding subwoofer setup. Its single-channel layout concentrates output on bass rather than dividing it among door speakers.

Key Features & Benefits

• Full-bridge Class D monoblock design for subwoofer systems.
• 7,000 watts RMS at 1 ohm; 3,600 watts RMS at 2 ohms.
• 1,800 watts RMS at 4 ohms.

Technical Specifications

• 1,800 watts RMS × 1 at 4 ohms
• 3,600 watts RMS × 1 at 2 ohms
• 7,000 watts RMS × 1 at 1 ohm
• 18,000 watts maximum power; this is not the continuous RMS rating

Why Choose This Product?

The TXP1.18000D is a starting point for a dedicated subwoofer channel, where channel arrangement and output at the actual connected load matter more than a headline maximum-power number. Compare the ratings above with the continuous requirements of the speakers you plan to use. Keeping those decisions together helps avoid buying an amplifier that is powerful on paper but wrong for the installation. For this model, the listed feature set includes Full-bridge Class D monoblock design for subwoofer systems. Check how that feature fits your intended system rather than substituting specifications from a similar model.

Installation & Compatibility Notes

Choose subwoofers and voice-coil wiring that present a supported final impedance. Compare RMS power at that load, and plan the vehicle’s charging system, power wiring, fusing and grounding for the installation. This is an amplifier for a properly engineered high-output system, not a substitute for adequate electrical support.

Plan the power and ground paths, circuit protection and mounting location before connecting the amplifier. Leave the controls accessible, protect wiring where it passes through panels and allow ventilation around the chassis. Set input sensitivity to the source signal rather than treating the gain control as extra volume.

Frequently Asked Questions

What continuous output is listed for the TXP1.18000D?

7,000 watts RMS at 1 ohm; 3,600 watts RMS at 2 ohms. Match the connected load to the stated rating and distinguish continuous RMS output from maximum power.

How should I choose speakers for the TXP1.18000D?

Match the amplifier’s documented RMS rating and supported load to the combined speaker wiring. Do not assume a bridged or lower-impedance configuration is supported unless it is explicitly specified for this model.

Does the TXP1.18000D need a gain setup after installation?

Yes. Set the input sensitivity to the source’s clean output and then set the filtering for the connected drivers. Gain is a matching adjustment, not additional rated amplifier power.
