Default 2012 GS - Audio question

I picked up a 2012 Grand Sport CE last June. I am in the early stages of upgrading the HU to the Alpine ILx-w650. Going through the car I found that a previous owner swapped the Factory Bose subs in the doors for 6 1/2" speakers. Rest of the car still has the Bose speakers. (i know there are some Bose haters out there but.....) I ordered new Bose Subs for the door to put it back to an all Bose system. The factory wire connectors for the Bose speakers were cut off. I have all the parts ordered and was wondering if there was a way to tell which side of the speaker is the positive terminal so I wire the new connectors correctly. TIA

can't say for sure but I used an app called polarity checker. it plays clicks and will tell you if it's out of phase or not. hope this helps.

and you might get more help if you moved this to the audio/electronics section

Put a 9V battery across the terminals. Positive to positive will move the cone "out", negative to positive will move the cone "in".

As long as the battery voltage is not too high, I like to stay below 12V to make sure the voice coil does not jump the gap by over-extending.
