Then maybe you can rig up an op amp front end with complimentary bipolar outputs.
But you'd have to design the circuit. Something along these lines, adapted for your parts.
You'd use two 9V batteries, not one.

That way you can use the TDA2822 as well.

i tried this tda thing and it haves heaps of noise..
Your TDA2822 pcb should have a DIP socket so that you can check the DIP voltages before you plug in the chip. That is normal practice for these little DIY amplifiers. Also there should be a volume control pot on the PCB close to the TDA so noise pickup is minimal. It should get music from the line output of a HiFi or portable player.
You need to provide a schematic or a diagram of your gear so that people can answer questions about it. A photo is not sufficient evidence.

Hi ,noise distortion and more
What is the origin of resistors, capacitors and those other components?
