Question about Car Audio & Video
I have a 15 inch mtx thunder 7000 sub that I have never really used, when i pulled it out of storage and hooked it to an amp, a sound was coming from the dust cap that sounded like something was hitting it, upon placing my finger on the dust cap, the noise ceased. the movement of the cone seems intact, does this mean the speaker is blown?
As dumb as it sounds, shake the speaker up and down with the speaker facing down. If the sound is there, there is possibly something inside the voicecoil that has come loose over time. If aetheitcs is important, stop here. The dust cover just keeps the voice coil from rusting. Use a box knife and cut a ****. Push one side of **** slightly inward. Prop it apart if you can. Shake till whatever is in falls out. A touch of silicone across cut will reseal.
