The power supply is cut by the most efficient MOSFETs available from the best manufacturer, International Rectifier (USA). They support 640A each, 175°C and there are 12 of them. We used 6 transformers to distribute the load and the temperature.Â
The energy storage at the power supply output is provided by 23 Elna capacitors, with low resistance and ultra fast. They withstand 105°C, but never exceed 60°C even after 5 days at full output! On the power stage, we used MOSFETs from International Rectifier which support 280A each.
To verify the correct operating balance of the RFL4001D, we monitored it with a $35,000 thermal racing camera. This allowed us to monitor the temperature of each component and the width / thickness of each track on the PCB. It's been a painstaking job, but the MTX RFL4001D performs much better than our wildest dreams. The RFL4001D is the highest performing amp ever built by MTX.

Please note: This high powered competition amplifier should be installed by a professional car audio store, with supporting power upgrades completed on your vehicle such as the ‘big three’, 2-3 matching/new batteries, high quality dual 0 gauge wiring and earthing. The final impedance of the subwoofer/s can not be below 1 OHM with a single amplifier or 2 OHM with 2 amplifiers strapped. If in doubt, talk to a professional. Warranty and repairs are honoured when these requirements are fulfilled in line with Australian Consumer Law.Â
