Need help with audio setup

**I do not know if this is the correct place to post this, so please forgive me if this is in the wrong place.**

 

Here is my situation:

I currently have two(2) Audio Source 8 ohm 100 watt bookshelf speakers, an Audio Source 8 ohm 100 watt center channel speaker (got this and the two bookshelf speaker for $20 at a thrift shop, basically brand new), and an Acoustic Audio 8 inch active sub-woofer with line level inputs. I currently have the two bookshelf speakers running off of a really old RCA amplifier with the sub in line between the amp and the speakers. This is connected to my TV for media consumption. The RCA amp is big, bulky, and just about to die, and I am also changing up my setup. I know that getting an A/V receiver would most likely be the best option, but I don't have the space or money for a good one at this point in time. What I want to know is how can I get all three speakers, and the sub-woofer running from my TV for under $100, preferably with an amp/receiver that is pretty small. 

 

I myself have come to the conclusion that with my constraints this is probably not possible. What I have come up with is using this amp board and an old laptop power supply to build my own amp and just use the two bookshelf speakers and the sub-woofer in line. 

 

What are your thoughts?

You won't get a multi channel amp/receiver for under $100 and if you get a stereo amp/receiver it will cancel the center channel but you can find stereo amp/receivers for under $100 on accessoriesforless.

Thanks. I will take a look at this.
