I don't want more power. I don't want to bridge them. I want to parallel them.
I hope this makes senses.
If it can't be done an explanation would be nice. I had read somewhere someone was thinking of doing it on there 4x100 board. One person seemed to think it would be ok and explained how to do it, but I want to be sure, so if you can explain why it can't be done, that would be great.

Sorry, I can not give a better explanation that has already been posted earlier in this post:

This post is related to Hifimediy amps. Earlier ones are T1 and T2, later ones are T3 and T4
iPhone has about 1V output and T2 takes 1.6Vrms.
It will work with no issue. Just you won't get the full power from the amp.
If at full volume you don't have enough power, you can increase the T2 gain a little.
It's by default 15 V/V.
You could increase the gain to 20 by lowering R1, R4 from 20K to 15K.
see tk2050 datasheet for detailed explanation of Gain calculation. T2 input and feedback stage is according to datasheet.

May I suggest that you try first a simple stereo implementation?
unless you want to build amplified speakers with physical separation of the amps, I expect very little benefit by going dual mono with these amps.
these are pretty common speaker specs. Most of the hifimediy amps will work well. It mostly depends on the power you want to get (how loud you want to play) and if you need or not onboard volume control.
A T2-510 with smps300R for example will be a good match. It you want to play very loud, T4 or T3S with SMPS500RS.
I have another idea. I think I will try a dual mono bi-amp setup, that way I can remove the resistive padding on the tweeter
What's thjis scheme for? I just installed an Nichicon gold of 220uf 50v in T2, and a 470uF 25V, some 100uF 50v for filtering the input also.
Haven't found an R24 in T2, do you think It should be fine like that:

don't be offended melon head, but are you doing any searching for yourself?
More infos ?
He likes to tease us! Actually I was hoping it might be a multi-channel amp. Something like 8 channels of T4 style would be wonderful!
But I'm still curious what this new thing is?

Right, this is a 4x channel/unit amp, and 8x when daisy-chain connect as picture shows. I use sta508 and get 80 Watt per channel. It works as cool as T1.
Looks like I had a semi lucky guess!
So now that you have teased us some more, how about letting us know when it will be available and how much $. And some more details please.
Sounds interesting!
