KrazyGlue from the dollar store
Hot Glue gun
Rubber gloves for handling KrazyGlue
Step 1: Take Them Out of Your Car
Mine were not the original car speakers, they were reused radio speakers.
Step 2: Put Some Crazy Glue
put some crazy glue under the center part by little sections and hold your fingers on and under the 2 parts for 30 seconds with ventilation for it to stick well. It won't look perfect once you're done, witch doesn't matters.
Step 3: Put Some Hot Glue
Put some hot glue in every little holes and then all around for isolation and to stop the speaker from making a cracking sound. And you're done. The speaker works like a charm now :) !
Step 4: Final Test
Overall it works fine but it takes away a bit of the subwoofing part, but doesnt really matter cause the left speaker compensate for it.
