Your post was a little hard to read.... (suggest proofreading for better "understandability")

That sounds quite odd...

Do you have a factory stereo?
What type of voltage is your alternator putting out?
I'm assuming you got the right battery...?

It sounds as if there is a faulty ground in the electrical system somewhere. You may want to check the ground from your alternator to the chassis. If it looks corroded or broken, replace it. I would just replace it anyways, for sure sake of better starting power. You could also add a couple ground wires from the chassis to the engine, via the timing belt cover, and the valve cover.
