BHG Watt Meter

I've got an earlier version of this Watt meter (15K) and it's a great unit. It easily allows you to find your lowest impedence so that you know you're not gonna damage your amplifier. It also lets you see the real time power numbers so you know exactly how hard you're pushing your amplifier. I also like to use it to test out amplifiers that I buy or repair to make sure they are working properly.

My only complaint is that it can't remember which screen mode it was in when you restart your vehicle. I like to see the Apparent Power, which is Raw power (Volts times Amps or VA mode), but whenever you cycle the system off and back on, it reverts back to the default screen, which is corrected power. This mode adds in the Power Factor which is a correction percentage and results in a reduced power number. Because the Power Factor can vary quite a bit, I think the Apparent Power mode is more realistic for people to use.

Without a doubt, this unit is way cheaper than the $450 AMM-1. I think that unit is more aimed at shop owners who are constantly moving it from vehicle to vehicle.

The Basshead Garage Watt meter is aimed more at the consumer who wants to install it and leave it in their vehicle so it's always there and running.

I definitely recommend it.

Pics are of me testing out an amp rated 300w at 4 ohm. It did really well.

well

i had to see what the hype was all about. they got it shipped the next day but with usps out of florida took over a week to get here. no fault of big jeffs at all. the unit itself is already cracked..i cant say it wasnt my fault because i didnt look that close at it from the get go. the meter reads slow but i can keep up with the ohm load at least. i tested against my volt meter and amp clamp and its within 15% and reads to the low side. every test i did this meter was lower power than what my volt meter and amp clamp read. cool lil screen to watch though...ooohhh....flashy lights!
