well i just got a JVC KD-BT1 deck for my 96 ford probe gt...and the installation was pretty easy....
i dint even do the amp bypass....all the wiring was done from the deck itself...
all stock speakers btw..


the front right and rear right sound perfect...
the front left is completely dead...and the rear left is low..
the volume of the left rear goes up kinda high when i pump up the volume...

we tried direct wiring to the front right speakers and the speaker seems fine when its direct..so im thinking its something with the stock wiring...
i dnt wana redo the wiring coz it will get messy with the wiring passing the wires to the door....

any ideas on wat i can do???

btw i tried the amp bypass....it just makes both rears die out...coz the amp bypass doesnt bypass the rear wires for some reason....

correct me if im wrong...btw the right rear speaker wires are separate...ie the green and green black....and the green red wires...that is also on the amp... if i bypass the amp...that set of wires doesnt go anywhere....

please help......
