Non-functioning cd player

Ok...I got a 95 Honda Civic hatch DX, Battery went dead, got it jumped then CD player wouldnt work. Well i took it out and the 12V constant was loose so i hooked it back up and the cd player magically worked...well i went out later to try again and the cd player then didnt work...so i tested all of the wires, checked all fuses and it seems that the 12v battery constant has nothing goin to it.....so.....how do i get around to replacing, and if I cant do it myself, anyone have a guesstimate on how much it would cost to get rewired

what kind of cd player do u have?
And if ur having trouble with the battery or the battery light comes on, its probebly ur alternator that's messed up. (not recharging)
However, if its not that, u could go to the car audio shop and have them rewire it for about 50 dollars more or less.
