so i didnt want to hijack the thread where i saw this but.... why? why is it when the HU is set to car type, tC, it only has the driver side woofer works? isnt that pointless? they put 2 woofers in the car, i dont understand why it would only run one?

 

I think we figured out that it was a programming flaw, not intentional...

 

i have this same problem and a problem with the drivers door ratteling (i think they may be related) if i had to guess it was supposed to be the other way around so that the sound centered around the driver and it was actually the drivers that was supposed to be "quieted" also i have been told that the 2011 have a stock 10" bazooka sub has anyone confirmed this or is this not true....

 

Guys it is a programming flaw with the Alpine head unit. Scion and Alpine are aware and slowly emphasis on slowly, working on a fix. No 10" sub stock in car..
