You can't just randomly throw an extra transistor in there - it needs connecting properly - why not just look at existing circuits like that?.
There's still no proper feedback - which MUST be DC, with lower AC feedback to give AC gain. If you're hoping for 30W your emitter resistors are also too high.
Here's an example of an excellent design, the Leak Stereo 70 - which provided a GOOD 35W in to 8 ohms, at high quality and low distortion - a classic quality design of it's day.
32W into 8 ohms is 45.3V peak-to-peak. Add maybe 6V for losses after you fix your serious losses with the high value emitter resistors and tiny output capacitor. Then the supply must be 51.3V.
But your supply is only 12V so you are lucky to get only 1W into 8 ohms.
