John Green –
Well, now I know how many watts my amp is putting out, how much voltage is going there, and how much box rise im getting.
Im very satisfied with this device! –
The difference with term pro lab magnum and this BHG-WM is about 200watts. And this reading depends on the range of watts it has to read. Like the lower the reading, the higher the accuracy.
Rosmeri –
Well can’t even use it…. it’s missing the connectors for the meter didn’t even get them…
Doc Loggins –
I absolutely luv this BHG-WM. Easy install. Easy to read and operate.
Abril_Ortega –
The concept is awesome but the material was vinyl plastic 3d printed material which when mounted, the vibration from Bass caused unit to blick on an off with pause, then cracked an split at mounting feet . Sadly disappointed..
Customer –
Does not show the correct wattage or ohm load.very inaccurate.extremely disappointed
