The left hand bass door speaker on my car has cut in out ever since I bought the car last July. I took it to a local car audio specialist soon after I bought it and he said it appeared that the voice coil, whatever one of those is, in the speaker was the culprit. Other things took priority and I didn't get round to attempting to do anything about it until the other day. Having bought a new pair of Audison bass speakers I replaced the left hand one and stationary it seemed fine. However when I drive the car it slowly dawned on me that the speaker seems to cut out when I turned left and back in again if I turned right? The drivers door speakers work fine with no cutting in or out. Is this just coincidence, my imagination or could there be a possible reason why this would happen? I'm assuming it will be the first or the second as the middle and tweeters continue to work.
