Hi guys ,can you help make recommendation on a budget-friendly 100W-200W home hi-fi amp which is happy driving 3 Ohms.
I need one to drive a pair of Alon IV. I don't mind a DIY or any off shelf solution as long as it's works.

For what you want and the loudspeaker company advises 200W not 100W I would suggest a mosfet power amp they are pretty un-burstable
at low impedance's.
It must have a very powerful power supply, weedy ones will not do but you mention--"budget friendly " that's not easy unless you DIY .
The speakers you have cost a lot and looking at the design & crossover which is non standard normal small power amps are not for you - big-beefy with big heat-sinks unless you buy other than class A /AB1.

I like the idea of DIY. Is there anything in the DIY category that fits. I currently have a parasound Hca 1000 that I am thinking of using for now. Any opinions?.
Looks like the specs of the Parasound would suite the bill.
200W into 4 ohms is good .
45amps peak says the power supply will cope BUT do NOT run it at FULL output as 2 ohms will damage the amp and 3 ohm speakers can hit that in places .
The manufacturer warns about this ---do NOT use in bridged mode --only ONE pair of speakers allowed to be connected .
Heed those warning and it will work --ignore them and I take no responsibility for any "burnout .

which of the DIY amps would you think would be a better fit , pass lab or honey badger or ?.
i want to squeeze the best performance out of the alon IV.

For the amount of power you want 200W out of the two you have provided Passlabs X250 fits the bill , Honey Badger is 150W.
A demo model in Reno Hi-Fi is selling for $7000 , this is anything but "budget friendly " though.
Reliable big power amps cost in hardware you could build but it still wont be cheap for the parts including a massive mains transformer .

back to square one, parasound seems to have vanished from the storeroom(not used in years) . A friend is offering to sell me a bose 1800. I feel its an overkill and might harm the Alon IV. Any thoughts or advise ?
Not recommended below 4 ohms --a bit high distortion at near full output --current/wattage increases at low loudspeaker impedance .
Kindly explain,do you mean the Bose is not recommended. Or settings below 4 ohms are not recommended
In the PDF of the specifications it is not recommended for use below 4 ohms .
When a manufacturer specifies a range of output impedance,s
of an amplifier it is for the safety and long term well being of that piece of equipment.
In this case the wattage increases significantly at a lowering of the impedance ,in many cases this is a good thing but at 3 ohms the current drawn would cause problems in the power supply and output .
If you look at a graph of a 3 ohm loudspeaker you will find it even dives down to 2 ohms at certain frequencies at that impedance if sustained can certainly cause a design that increases in drawn current at lower impedance's that isn't designed for it to fail.
Many power amps are limited that amp isn't .
You can buy it ,its your choice but if you plan to use the full
wattage then,as I said problems will arise .
You can completely ignore my post its a free country but I am going by the manufacturers recommendations .
