Product Description
Technology and innovation are keystones of Massive Audio and now Massive amplifiers are even smaller with “Nano BiT”. With 3 models to choose from Nano BiT is expected to once again change how consumers view powerful amplifiers with a small footprint. Before now pure digital amplifiers were less desirable due to levels of high distortion on high wattage devices. Massive Audio has developed a new platform that utilizes brand new technology to greatly reduce amplifier size and distortion. This new cutting edge technology means clean high power output in a shell only 1.6” high and 5” wide! All this with OEM auto sensing music remote turn-on speaker level inputs and 12 volt remote out for other devices in the system means it’s time to change the world again!

I just want to add to this since my purchase was based on your review. Thanks btw.
I installed 2 of the bx4′s on Saturday. Using 2 channels for audible psychic full ranges, 2 for Dayton 8in midbass and using internal amp crossovers. KISS right? Lol
The other amp is for rears and bridged mono for focal sub.
I have several test tracks that I’ve used for many years in home and car systems to evaluate dynamics, micro dynamics, impact, power, and control.
These replaced my ARC audio KS series amps. I’ve also used Alpine and jl digital amps in current ride.
For the size, the power is actually very good. The control of sub and midbass really surprised me. My 13in focal is quite efficient but still… how can an amp this size (actually half the amp) control a sub so well? An amp that you can’t fit 4 gauge wire in without trimming half the strands. An amp that has speaker wire terminals that used the smallest alan wrench I had (it comes with nedded tools but I chose not to open accessory package) in my box? Truly amazing
The imaging, which I believe is mostly attributed to install and ta, was as good as with my other amps. I could find nothing missing or anything the massives couldn’t do that my other amps did.
To sum up…. if you want stealthy, efficient amps this is a no brainer.

Well, I have two channels of the BX4 running an IDMAX12 and it sounds really good. I have also ordered another BX4 and a B2 to run my entire system. I will have one BX4 bridged to a pair of HAT L6′s, the other BX4 will run a pair of L4se’s and L1v2′s, and the B2 will run the IDMAX12. Thanks again Massive, these little amps are impressive!
