We now know it's for home use and partying and it's 8ohm.
Give us some more clues.
10W or 100W or 1000W?

Honestly, a power amp for PA use (lots of watts) you would spend more building one than you would just to buy one. The heatsink, transformer and case alone would cost a lot, and then a whole lot more for good (real) output transistors.

Perhaps a Class-D subwoofer amplifier for the woofers, as part of an "active" system?

Here's a short list of some sub amps:

On this type of amplifier, the power is given as if you have a 4 ohm load, so they will produce roughly half as much on an 8 ohm load. Its not a defect--that's just advertisement stuff.

Also, check out products for "Prosound," "PA," and "DJ," in your local market. Those are the products that produce the nightclub sound.
