Thread: door speaker size and rear speaker size?

i want to upgrade the speakers in my car and wasnt sure on the size. they look to be 6.5's all the way around but i want to be 100% before i get anything.

You are correct.

thanks for the help^

anyone know which color in our cars is negative and which is positive?

look at a wiring diagram

Pretty sure on the speaker wires, the one with the black stripe is the negative.

I got it.

Front Speaker Left: ( - ) G/W ( + ) P
Front Speaker Right ( - ) Br/W ( + ) Br

Left Speaker Rear: ( - ) B/P ( + ) Or
Right Speaker Rear: ( - ) Gr/R ( + ) Gy

another way to tell is to have a speaker connected and use a AA battery to pop the speaker. Solder a wire to each end of the battery, careful to not overheat. connect the positive to one wire and the negative to the other to a speaker. if the speaker moves out then the polarity is correct, if it moves in then just reverse the wires. The positive battery wire is now your positive speaker wire.

^^^ One of the few tricks learned when doing audio.

yup, thanks wayne and squirlz for the info. i actually just finished installing the drivers side speaker and it works fine but after i installed the passenger side speaker, no sound comes out. the factory speaker didnt work as well and didnt play music either. i know that everything was wired correctly which makes me believe its something to do with the headunit.
