The Down4Sound TEEMFIDEEN KAY monoblock amplifier is engineered for extreme bass systems that demand relentless, controlled power. Rated at 15,000 watts RMS at 1 OHM, this amplifier delivers massive output with the stability and efficiency required for high-demand daily systems, long demo sessions, and competition-level builds.

Built around a high-speed MOSFET power supply and a high-purity copper PCB, the TEEMFIDEEN KAY maintains low distortion under heavy load while providing the headroom needed to push large subwoofer arrays hard and clean. Advanced tuning controls, onboard protection, and a feature-rich wired remote make this amplifier as functional as it is powerful.

When strapped, two TEEMFIDEEN KAY amplifiers are capable of delivering up to 30,000 watts RMS at 1 OHM, making it a serious solution for full-scale bass builds with properly designed electrical systems.

Power Advisory – Electrical System Requirements

The TEEMFIDEEN KAY is a high-output amplifier that requires a properly designed electrical system for safe and reliable operation. The specifications below apply to TEEMFIDEEN KAY amplifiers only. Any additional amplifiers must be supported with independent alternator and battery capacity.

Minimum Electrical Requirements – One Amplifier (Daily Music Use)

Single Alternator Setup (Not Ideal)

• One 370A–400A high-output alternator

• Idle output no less than 180A–220A

• Not recommended for demos or extended high-power sessions

• Battery bank must absorb peak transients during voltage drop

Dual Alternator Setup (Recommended)

• Two 320A–350A high-output alternators

• Combined output of 600A–700A at cruising RPM

• Minimum 400A combined at idle

• External regulation recommended for stable charging between 14.4V–15.5V

Electrical Requirements – Two Amplifiers (Strapped – 30,000W RMS)

Minimum Charging Solution

• Three 320A–350A high-output alternators

• Combined output of 960A–1050A

Preferred Charging Solution

• Four high-output alternators rated 320A or higher

• Total charging capacity of 1200A–1300A

• Does not include headroom for additional amplifiers or accessories

Recommended Lithium Battery Capacity

One Amplifier (15,000W RMS)

• 120Ah–160Ah total lithium capacity

• Typical configurations:

  • 6S3P to 6S4P (LTO 40Ah)

  • 4S3P (LiFePO₄)

• Common cell type: Yinlong 66160H

Two Amplifiers (30,000W RMS)

• 240Ah–300Ah total lithium capacity

• Typical configurations:

  • 6S6P to 6S8P (LTO 40Ah)

  • 4S6P to 4S8P (LiFePO₄)

• Common cell types: Yinlong, C-Max NMC modules, large-format prismatic LiFePO₄

Important Notes

• Specifications apply to TEEMFIDEEN KAY amplifiers only

• Each amplifier is fused for up to 1120A peak current draw

• Power and ground cables must be sized for full current load

• Battery banks must support sustained music playback, not just SPL bursts

• Maintain stable system voltage for optimal amplifier and lithium performance

• Balancers or BMS systems are required for safe, even cell voltage

• Professional installation with proper grounding, fusing, and cable routing is strongly recommended
