This is the closest I've gotten to a working amplifier but the output is still too small for my target. Can someone help me???

Here's a basic CE-CD amplifier to get you started: http://everycircuit.com/circuit/5444708609556480

What would you like to accomplish, sshsslfun?

I'm trying to get the output power to be a max of 15 watts, the highest I've gotten is 2.5 Watts. Thanks for the help!

After adding another stage I got the same results as the 1 stage version. So, what I think is happening is that Im forgetting to amplify the signal(Im new to electronics if you can't tell.). Im going to do some trial and error as well as look through examples. Thanks again @sshsslfun

Also something I noticed, the input Wattage is 0.02 Watts and output 0.1 Watts so theres atleast SOME amplification

Yes, what you built is a class AB amplifier. At best you will get near a gain of 1. If you want gain greater than 1 i suggest looking into a Common-Emitter amplifer, then go from there.

Im encountering smaller problems, I'll have to go over my notes again to see what I've got to do.

@sshsslfun You're welcome. If you're looking to push current to a 4ohm load you will likely need a power amp output stage similar to what you built here. So, it's a good start. Keep at it my dude.
