Still working...
|
Time owned: 6 to 12 months

Almost a year later, this amplifier is still working in my mobile. However, I am unable to get full output using the "recommended" wire gauge and length for full output as stated in the manual.
Using 8-gauge wire at 11.5 feet, driving with 25 watts, I only get 140 watts on a dummy load with 13.8 volts in.
After doing some checks, I found that the amp appears to absorb 15% of your input power, regardless if it is ON or OFF. This seems to explain why the amplifier does only a 140 watts in 25 watts of drive.
Attaching a good watt meter directly to my radio, it measures exactly 25 watts. Attaching the Mirage amp (turned off), it drops to 21 watts. Doing it again at full radio output, it measures 72 watts (Icom V-8000). However, placing the amp in-line reduces it down to 61 watts on the output side of the amp.
Any thoughts as to why this happens would be appreciated.
