Bought a new (second hand) cd player, its an alpine slippy screen one with alpine 6 disk changed, plugged it all into the iso plug today, when cd is playing it only comes out of my 6x9's and there is no volume control simply on or of (0 being off - 1+ being on) but when its on radio all speakers work and and volume control is back, also when cd is playing i can make beeping noises when playing with the controls etc and the bleepy noises come from all speakers and is controlable by volume, so what is it?! Problem with changer???
Any help asap greatly appreciated
