Rockford Fosgate T1500-1bdCP Power 1,500 Watt Class-bd Constant Power Amplifier

With the Power T400-2, you get a lot for your money, considering the ‘Power’ series of amplifiers are Rockford Fosgate’s flagship offerings. From high-quality connectors (to reduce quality degradation at the connection) to the wrap-around heat sink with dynamic thermal management technology to reduce distortion-causing hot spots on the amplifier body, it’s clear that the designers at Rockford Fosgate sweated the details.

Power levels range from 120 watts RMS to 2 channels at 4 ohms, 200 watts RMS to 2 channels at 2 ohms, and up to 400 watts RMS in bridged mode at 4 ohms. The circuitry of this amplifier uses advanced algorithms to prevent distortion and interference, and the differential input design ensures that the signals do not cross-contaminate. This is a highly capable, reliable amplifier that reveals no significant flaws, as one would expect from a flagship product from a manufacturer like Rockford Fosgate.
