    This IC chip was designed specifically for use in power boosting applications in automobiles. It is self protecting against short circuits and thermal problems.In the bridge configuration shown it will deliver 20 watts of power into a 2 ohm speaker operating at 14.4 volts.

    No way.
    Build a larger more complicated circuit for the 250W.

    For a sub you'll need a lot of power and it'll almost certainly be cheaper to buy a ready made one.

    Sort of?, they are POWER operational amplifiers, but specifically intended for audio use.

    no way!!!

    you cant get any more power on that IC

    its characteristic is the same as LM2005T

    20 watts bridge connection

    for a 250 watts, you can only attain this power by using higher supply voltage such as +/-35 volts

    :)

    Oh I think we can squeeze 250 watts out of that circuit.... say IHF ratings at 1kc. for 1 microsecond.

    The TDA2005 isn't a hi-fi amp, it is a car radio amp. Its distortion is typically 0.3% (1% max) as a 2-channel stereo amp, up to 6W RMS per channel into 2 ohm speakers and a 14.4V supply.
    If you want very low distortion then use a hi-fi amp IC. They need a supply voltage much higher than a car battery and drive 8 ohm speakers.

    High End Audio Amplifier

    Is there anyone interest with creating new Hi-End Audio Amplifier thread?
    I've initiate it, but I've no access to do it.

    I'll help to start it with my 7th version K32 that been fixed in dec2005.
    And also analyze old halcro schematic.
