Will AB Power amplifier reduce gain?

I'm suppose to design an amplifier that is able to drive a 8 ohm speaker.
I have designed the 1st stage amplifier using CE Configuration. I need power amplifier to drive the speaker, so that I can implemented it in hardware. But will the gain decrease?
My design:
Icq=4mA Vcc=15V
R1=33k R2=5.6k
Rc=1.8k Re=0.33k
C1=C2=10uF
Ce=100uF

I assume Ce ( 100 uF) is bypass Re (0.33K). The collector voltage is 7.8 volts (15 - 1.8k * 4 ma). V emitter is 1.3 volts, the base voltage is about 2.1 volts. The internal resistance re of the transistor is 26/(4ma) = 6.5 ohms. You're expecting a voltage gain of - 1800/6.5 = -270. The internal resistance will vary with collector current making this a very non linear amplifier. You need to provide negative feedback to reduce the distortion. The power amplifier will reduce gain slightly. By the way the power amplifier is an impedance matching device.
