so i just bought a deck for my 2003 acura tl and my factory mini sub or speaker behind the backseat isnt working. i think i missing a wire but dont know which one it is. if im not missing a wire then iono wats wrong.

 

If you had spare wires on the OEM harness that you didn't connect up, there could be your problem. Also, check to make sure you wired it correctly, and didn't splice two wires incorrectly.

 

well there was an extra plug that i didnt know wat it did. the oem radio had two plugs connected to it but i only used one of them to connect the deck. i remember a best buy guy said that i needed a wire or else it wouldn't sound as good but when i bought it the next day a different guy said everything is there so i think im missing a wire.
