Has anyone had good experience with the Massive P65X coax speakers in the fairing? The specs look promising.
The NVX VADM4 amp is on sale for about $150, anyone run fairing and lowers off this amp?

Have not used those speakers, but have that amp, it's a good amp and very small. That amp will interfere with FM reception if that matters to you. I don't think that amp has enough power to run 4 of those speakers. Rated at 75W per channel puts out closer to 100W per channel. Those speakers are going to probably need 125-150W each.

If you got close to 100 watts out of the BLX4 amp you got lucky. The 2 that I tested so far didnt even get close to 85 watts in stereo and 210 watts bridged. That was with 14.5volts DC going to the amps and they are rated at 120 and 480 at 14.4.

I think it's a China thing more than anything but this last batch of "Holiday Special" amps that Massive sold at half price are coming in quite a bit under spec. And Massive Tech Sup is playing dumb.
Same deal does with others. I stopped buying the NVX Chinese stuff as well. One amp is above spec and the next 3 are dirty as hell.
Just depends on what day of the week these sweat shops decide to implement quality control. Or whether the Brand owners force quality control standards that are expected.

As u can tell, I'm way cold on China for many many many reasons. Test all that Chinese shix immediately after coming out of the box and send that shix back if it's not within a reasonable margins of advertised spec ASAP. And hopefully this group does a very good job vetting these products and sharing QC info day in and out.

So the million dollar question is what companies deliver a consistent product and what ones don't?

I was referring to the NVX VADM4 amp. Sorry for the confusion. Are you also testing a TX48?

Are you still running there tx48? Not that I would buy from them again. But yea that's bs. I agree they need to make it right.
Yeah I still have it in play but I must have gotten mine from the sweat shop on the other end of town. It's not beating spec but it's at least within a reasonable margin of error.

But my sled is under construction and this Massive TX48 is coming off the sled as a China QC boycott if nothing else.

Lots and lots of product options have come available over the last couple of years, but very few of these products are consistently good quality products.

I’ve been trying to tune my brand new TX48. Did some more testing last night. With my bike running, battery testing at 14.3 and using DD1, I got 144watts regular and 598watts bridged of max clean signal.

I should be getting 200w and 800w. So much below rated specs.

I have emailed tech support. Waiting for a reply.

That NVX is hit or miss brother. Depends on whether Ling Ling, ****, Chen, or Yang builds it.

How do you test for clean signal? Can I do it with my oscilloscope multi meter ?
