The Star Power 1500 amplifier is a single channel Mono amplifier designed to run at a 1 ohm load and is rated to produce 1500 Watts or more at 14.4V.

Star Power amplifiers are designed to offer better than rated power output capabilities along with the maximum possible reliability. These amplifiers will meet or beat their rated specifications

Star Power amplifiers can be linked together (strapped) so that 2 amplifiers can be combined to run as a single amplifier.

Standard version features include:
0 AWG Power and Ground terminal blocks (Dual for Star Power 5000)
Tiffany style RCA connections
Remote gain control knob
Clipping indicator (located on the amplifier and the remote gain control)
Protection indicator (located on the amplifier)
Thermal/Over Current/Speaker Short/Speaker DC protection circuits
Pink colored Double-sided epoxy PCB
Pink power LEDs
Custom tooled star heatsink
Reversible logo panel
