Cd Stacker Help

[J-MuN]

wat do u mean by "that allows you to use rca cables linking from speaker wires"?

and a wild shot but what stacker are u using?... factory like the head unit?...

[clikz]

Are you using the rca adaptor? where you use your rear speakers to connect in place of rca connectors that you don't have on the deck?
Is your amp light on and working etc?
