I don't think that anyone has had this problem. I have had my TSX for 9 months.

One day, I was playing my stereo and while playing it loud, all of a sudden, the front speakers did not work. I thought that I would just get it fixed in a month or so when I get my oil changed.
Then my car would not start. After jumpstarting the car, I took it into the dealer. The problem was the Amplifier. Since this is under warranty, everything was fixed for NO CHARGE. Here is the explanation of the problem.

"THE CAR WOULD NOT START. BATT IS DEAD. RECHARGED AND TEST BATT. BATT IS GOOD. CHECK FOR PARASITIC AMP DRAW. WTITH EVERYTHING OFF THERE IS A 878 mA DRAW. PULLED FUSES TO ISOLATE CIRCUIT. WHEN REMOVING BACK UP FUSE THE AMP DRAW DROPS TO 38 mA. TRACED BACK UP FUSE CIRCUIT. FOUND THAT STEREO AMP WAS CAUSING AMP DRAW. AMP HAS AN INTERNAL FAILURE THAT IS CAUSING CONSTANT POWER DRAW WHEN UNIT IS OFF. REPLACED AMP. RECHECK PARASITIC AMP DRAW. THERE IS A 38mA DRAW WITH EVERYTHING OFF-OK.

So if you front speakers do not work, see your dealer immediately.
