Single Supply Audio Amplifier

I am currently designing an audio amplifier using the LM324. I am operating from a single supply of 9 V. Here is the schematic:

Here are the design steps I took:

1. I needed a gain of 100 so G = 1+(100/1) = 101.


2. The input capacitor C1 forms a high pass filter with R1||R2. The lowest frequency is 20 Hz so I chose f=15 Hz and C = \$\frac{1}{2\pi\cdot 5000\cdot15}\$ = 2.12 µF so I chose C1 = 4.7 µF as the closest value.


3. The non-inverting input is biased to V_CC / 2 to allow maximum output swing.



4. C2 is just a normal decoupling capacitor.

After assembling it I am unable to get a decent output from it. Can anyone point out what could be the problem?
