CT Sounds CT-1500.1D Compact Class D Mono Block Amplifier | 1500W RMS

Powerful, compact CT Sounds CT-1500.1D Class D Mono Amplifier

The CT Sounds CT-1500.1D is designed for car audio enthusiasts who want serious subwoofer performance without sacrificing cabin or trunk space. With a 14.4V electrical baseline, it delivers up to 1500 watts RMS at 1 ohm, 850 watts RMS at 2 ohms, and 450 watts RMS at 4 ohms. The amp supports a broad frequency range from sub-bass to bass, spanning 0 to 320 Hz, and includes a dedicated bass knob for on-demand tonal shaping that complements a variety of subwoofer setups and listening preferences.

Uncompromising power in a small footprint

Don’t let the compact chassis fool you. This mono amplifier is built to move air with authority, making it ideal for tight installs in hatchbacks, sedans, or compact trucks while still delivering substantial bass impact. Its footprint is designed to give installers more flexible mounting options without giving up headroom in your sub stage.

• Compact chassis fits tight spaces in most vehicles
• High power at low impedance supports robust subwoofer performance

Efficient, cool-running design

The CT-1500.1D uses a MOSFET pulse width modulated power supply paired with a proprietary heat dissipation design. This combination helps the amplifier stay cooler during extended listening sessions and maintains steady performance across playlists with dynamic bass.

• Efficient Class D operation for reduced heat
• Advanced heat management helps sustain performance

Protection and peace of mind

Built with four-way protection, including high voltage, low voltage, over-current, and high-temperature safeguards. These protections are designed to help prevent unexpected shutdowns and provide reliable operation in varied vehicle electrical conditions.

• High and low voltage protections guard against surge and drop
• Over-current and high-temperature safeguards for ongoing use

Real-world use and benefits

In practice, you may experience crisper bass response, cleaner transients, and better control over subwoofer output. The included bass knob makes real-time adjustments easy, while the 0–320 Hz range keeps the amp focused on bass frequencies for subwoofers. This setup is well-suited for upgrading stock systems or pairing with aftermarket subwoofers where space and power balance matters.
