Based on customer reviews

Very high‑output, clean sub amp that often exceeds its rated RMS

Delivers massive, often-underrated power with clean SQ and efficient cooling—excellent for driving subwoofers loudly; just ensure your subs and tuning can handle the output.

44 reviews5.0/5 averageUpdated Mar 15, 2026

What buyers praise

  • Very high output—multiple reviewers report it meets or exceeds the listed RMS
  • Produces loud, deep bass across 10–15" sub setups

What to watch for

  • Powerful output can be overkill for smaller subs—match sub RMS and set gains/tuning appropriately to avoid overpowering
Overview

The Power T1000-1bdCP is a 1,000 Watt class mono Class-BD amplifier that uses a Constant Power configuration to deliver up to 25% more power across impedance loads and is optimized for subwoofers.

Best for

  • High-power car subwoofer systems
  • Single-channel (mono) vehicle audio installations
  • Setups needing consistent power across varying impedance loads

Key points

  • 1,000 Watt class mono amplifier
  • Constant Power configuration — delivers up to 25% more power across all impedance loads
  • Frequency response optimized exclusively for use with subwoofers
  • Class-BD topology
  • Technologies: CTA-2006 Compliant, Balanced Differential Inputs, TO-247 MOSFETs, MEHSA3, Punch Bass EQ, DSM, Engineered In The USA

Fit and use

Designed as a single-channel amplifier for vehicle subwoofer applications. Use where a dedicated, high-power mono amplifier is required and where frequency response optimized for low-frequency reproduction is desired.

What to know

This amplifier is rated as a 1,000 Watt class unit and uses Constant Power to increase output across impedance loads; actual system performance depends on speaker selection, enclosure, wiring, and overall system design. Measurements follow CTA-2006 compliance where specified.
