Digital Amplifiers / D Series
The Interfire D series Class-D digital amplifiers have been proving themselves all across the U.S. especially in all of the competition lanes.
The D series are true 1 ohm stable amplifiers with all the features needed for pushing out the absolute most power per square inch. At only 20 and 12 inches long, D1700.1 gives you 1100W RMS continuous. The D1700.1 featuresa remote controllable bass boost via the included bass boost remote controller. A quick look inside reveals some good craftsmanship, high temperature handling capacitors (105 degrees), over-wrapped torroidial coils, wide trace separate board outputs, gold plated bus bars, intelligent protection circuitry and full Bridge Syncability.

The Interfire D series Class-D digital amplifiers have been proving themselves all across the U.S. especially in all of the competition lanes.
The D series are true 1 ohm stable amplifiers with all the features needed for pushing out the absolute most power per square inch. At only 20 and 12 inches long, the D3000.1 & D1700.1 gives you 2200W and 1100W RMS continuous. Measuring just over 9 inches, the D900.1 delivers 600W RMS continuously Both the D900.1 & the D1700.1 feature a remote controllable bass boost via the included bass boost remote controller. A quick look inside reveals some good craftsmanship, high temperature handling capacitors (105 degrees), over-wrapped torroidial coils, wide trace separate board outputs, gold plated bus bars, intelligent protection circuitry and full Bridge Syncability. Features Class-D Digital Technology High Efficiency PWM Power Supply 4 Gauge Gold Plated Machined Power Terminals High Temperature Power Capacitors (105 degrees C) Gold Plated Bus Bars Overwrapped Torroidial Coils Fully Variable Low-Pass Crossovers Heavy Duty Power Capacitors Super Small Footprint Soft Remote On/Off Circuitry Intelligent Protection: Over Voltage/Thermal/DC Offset/Short Bridge Sync Capable Need External Fuse-minimum 180amp (D3000.1) Over-wrapped torroidial coils, gold plated bus bars, high temperature capacitors, bridge-sync ability and intelligent protection circuitry puts the D series amplifiers in a class of their own.
