Something that can finally drive these wired in parallel?!

Why would you wire them in parallel to drive with a bridged amplifier? Why shouldn't you use two sets of wires and drive each coil separately?

Honest question, i'm planning a car system.

I was half kidding because I’ve been thinking about using those drivers but their sensitivity stinks. I do mostly active builds but Not for a car so I wouldn’t want one driver to take up 2 channels, and honestly not a monoblock either. A home 2 channel amp that can do 2 ohms on the cheap with good sinad is attractive

Here's a preview of V3 mono internals and back photo.

Nice. Volume bypass ?

There isn't any Volume Pot, so isn't it volume bypass by default then?

Just saw the front panel ) thanks

But where is the trigger input?

It has a permanent place in the "WISH LIST"

It has a permanent place in the "WISH LIST"

and so, seems like "AUTO" is supposed to work with signal sense in the absence of triggered-in!

For me the DC connector is too close to the binding posts, should review this design :

I noticed that when I saw the pics, but then I thought it might be the angle making it appear a bit closer than where it is.
But it is close enough to be slightly worried, specially if someone is doing bare wire or spades than banana plugs.

Maybe, but I would not worry about it. The DC male connector that plugs into the amp chassis socket will have a plastic jacket that will completely cover any exposed metal when plugged in. Also, there isn't really a need to simultaneously connect the speaker wires and the DC power, since the amp should be switched off and disconnected when doing so.

Keep in mind that these sort of binding posts are usually very underwhelming, e.g. too small and flimsy, so using banana jacks instead of screwing the BPs down onto bare wire is probably a far better connection option anyway. This is the parts quality you can expect for such low cost electronics.

Audio sense is a great feature, but needs to be well implemented.
My Boxem amp works great, my old svs subs weren't that great.
Let's see what the beta testers early buyers report.

Anyone here is a beta tester?

We can translate " Class D with bad Sinad" works too lol --)))

Class doesn’t translate into SINAD. You have good and bad implementations.

It was a joke ) I own many amps

Hummm it s not the angle for me.... Check without binding posts

I'm extremely curious! This could be what I've been asking for years... I just need it to be sufficiently non-dependent on the load, with a sinad over 85 and at least 100watts into 8ohm at all frequencies and I'd take 5/6
