Hello all and thanks in advance for any help. I've happily driven my 09 Base V6 (non JBL) for a few months now and my only issue has been with the drivers side speakers being intermittent. Both front and back woofer are inop, but the tweeter works as usual. I've had the problem with both the stock head and a Sony I installed recently, so I just wanted to see if there is a common point of failure before ripping both door cards off. Thanks!
