[300cMexico]

Hello. I have a mexican 300c and it came with the sound group II which they claim has 7 speakers. The audio is excellent but the bass seem to only come from the front doors. If i move the fader to the rear I get no base at all which leads me to beleive the i only have mid-bass on the doors.

I have read several threads mentioning that they have a subwoofer in the trunk. is that visible buy looking in the trunk?
