Audio Systems: after market stero in 2001 dodge ram 1500, dodge ram 1500, stock speakers

Question
i have installed a after market radio in my 2001 dodge ram.power is working,but door speakers are not.i have used a compatibale hareness, still nothing. so i wired direct,still nothing.i changed decks,no help.everything is wired to wireing specks.if i hook up the stock radio everything works. is there a ground issue for the stock speakers when converting to after market? please help....

Answer
there is a white wire on the factory harness and and blue wire in your new harness connect them together
that will turn on the INFINITY amplifier and the speakers will work again

also make sure you ground the radio, just like the factory big heavy cable in the back side of the radio
