You've asked this before, it was answered, then you answered you wanted to design one yourself. So which is it? Have you looked at the previous designs?

 

yes i designed an 8 watt power amplifier that was my home work task i submitted that now i am free and tell me about sound system that i can use for my desktop pc and car.
i submitted that 8 watt amplifier made on proteus but now i want to make it in real and i want good quality sound like woofer's for my pc and car for that i want to know how to design or else if there are some already made design's because first i was going to purchase but then i thought i should made myself i have 7 days left then again i will get busy if you guys have design tell me i will be thankful

 

Your "8W" amplifier had many problems.
Maybe you should buy amplifier ICs and make a pcb according to the recommended one shown on the datasheet. Or buy amplifier kits.

 

Good answer, AG.
