The sound really is awful in my 997.1, even with an upgraded Nav/radio. Thinking about a subwoofer, but I don't want to lose a back seat. Anyone have pics or links of where they placed a sub? Thanks

 

Focal iBus 20 and put it under the seat.

 

Google "porsche 997 subwoofer enclosure" and lots of things show up including this.

Its a 12", but could of probably went with a 10". Its a shallow JL TW. More than enough deep low bass, went with a sealed enclosure for that tight acurate bass versus the ported enclosure like the stock Bose subwoofers.

 

Thanks guys. I will do some research....
