design your own circuit . see these link **broken link removed**

Use new ICs from NI,Maxim etc

The amplifier is trivial, just aim for enough power down to subsonic frequencies (very large coupling capacitors). The problem is with the loudspeaker, you just can't cheat on the physics, you need to move a lot of air, so long throw voice coils/large diameter cones and very substantial cabinets both in volume and rigidity.
Many so called "bass boxes" actually produce most of their audible power at twice the audio frequency due to high distortion and a cabinet cut off which won't allow the cone to move at the fundamental frequencies.

Has made one on test, based on TDA 1562


but after LME49830 all other not want to take in hands
