Hi, im trying to build an amplifier with 2 stages, common collector and common emitter. I biased for midpoint operation in them but i have a gain of only 1, dont know where im going wrong.

R14 is only 8 ohms and this is in parallel with the load resistor R2.

Without it, the gain should be a bit less than 4. ie 800 / 200
