When designing this amplifier the goal was clear, maximum power in the minimum amount of space. With 300 watts squeezed into the smallest of enclosures, this amp truly has to be heard to believed, so if you're short on space but don't want to sacrifice on sound, this is for you!
High and lowpass filters allow precise control over your sound. With robust housing and well engineered internal components, all in a brilliant compact design, this little gem wont let you down!

[1] How do we correlate the "300W max." and "2 x 30W RMS" power? I thought Max. Power (Pmax) = 2 x Power in RMS (Prms)...
[2] Usually home audio amplifier do not state "low pass filter" or "high pass filter". Why do we need these specs in a car audio amplifier?
[3] Is it good to have a HIGHER or LOWER input impedance? What is the typical input impedance of an audio amplifier?
[4] Does the "Output impedance: 4 to 16 ohms" mean the output impedance of the audio amplifier or the impedance of the connected speaker?
Looking at the rest of the specs, this does not look like a very good amplifier. First of all the power is quite low, comparable with a modern CD player source. The low frequency response is acceptable but dont connect this to a subwoofer.
A random distortion figure is given. I take it it refers to THD+N distortion? Who knows. Anyway it says >0.1% Note the unequality symbol meaning greater than 0.1%! Possibly 0.5% or 1% is what they meant? lol. This is a terrible figure from a modern transistor amplifier.
I would suggest you continue looking for a better amplifier. What system do you have in mind overall?
This could be taken out of context as 'V' changes from amplifier to amplfiier. Take the TDA1562Q operating in class H for example. It uses two switched capacitors to boost its power supply during signal peaks.
Bandwidth is meaningful, for amplfiiers -3dB is the norm, I assumed this is the case here. But who knows seeing how the other specs are inflated.
The specs are improving :-D
But your power supply is intended for a main connection (240V AC)!
You need 10-14 or thereabouts power supply voltage.
I see. What sort of power and peak voltage do you want in your toroidal transformer? Whats connected in the secondary? If this for a step up converter you can tolerate a lot of distortion from your power amplifier.

Found few more as below. What do you think about them? Do you think I can use them for my application as a "variable-frequency variable-amplitude sinusoidal voltage source"? Thanks.

Yeah right, assuming 2*30A fuses in parallel, it's 60A which at 12V is only 720W. All the other specifications are total bollocks, I'm not going to waste my time debunking them.
Got to love car power amplifiers.
1mm, how much power do you require in your transformer and at what primary voltage? Maybe you can get away with a power op-amp? Maybe a few transistors? We have no clue as to what you are trying to do.
