Going a different direction with the next boat audio system so selling my stockpile of D7 amps that I have collected over the years......they don't make these any longer. These are american made hand built amps, what a novel concept. I was going to use 2 4-channels and 1 2-channel and bought the others for spares. Anyway, they are all for sale...$350 each.
Have 5 amps total:
(3) 4 channel 7104's
Specs:
D7104
100W x 4 @ 4 Ohm Stereo
200W x 4 @ 2 Ohm Stereo
400W x 2 Bridged @ 4 Ohms
Symmetrical Topology, Fully Regulated, Triple-Split-Rail Power Supply
Isolated Input Section Utilizing "Quasi-Differential" Instrumentation Amplifier Technology
Third-Order 18dB/Octave Butterworth Crossover Topology
Wide Bandwidth/Low Distortion Symmetrical Gain Output Stage
Gold Plated Copper Circuit Board
High Efficiency Intelligent Thermal Management Protection System
Massive 3-Piece Proprietary Heatsink
Solid Copper High-Current Power Distribution Busbars
S/N Ratio: 102 dB
Frequency Response: 3 Hz - 50 kHz
Dimensions: 24-3/4"L x 10-5/8"W x 3"H
(2) 2 channels 7402's
D7402
400W x 2 @ 4 Ohm Stere
800W x 2 @ 2 Ohm Stereo
1600W Bridged @ 4 Ohms
