Hi Guys,

This is just FYI in case you consider Infinity BassLink II as your bass upgrade for your US standard sound system.
Last week, I was about to order this sub online which was about $290. But, I thought to myself that why didn't I try it first by buying it from local store. Brought it home and tried it on my sound system, and I felt disappointed whether the trunk is closed or opened, and gain is set to max. It does not sound loud and good enough at all, so I returned it. I thought to myself that I'd rather trade in for new E60 than upgrade the sound system in my current E60 530i.

Regards.
