I have a 2012 Lexus IS F with the Mark Levinson sound system package. I like the clarity and detail of the factory given ML speakers. The mids and highs are great, but it lacks in the low end bass. So I wanted to add a better balanced subwoofer stage and to remove the factory subwoofer. The objective of the install is to make it stealthy, factory looking, simple, and clean.

First thing was to remove the spare, use factory mounting locations (no drilling)
Installed the remote bass **** control to the stock empty slot on the right of the steering area
The factory accessory mat does lay perfectly over the false floor, becomes flushed and stealthy
The subwoofer blends very well and smooth - never over bearing to the stock speakers. It is very accurate, plays low, and can get loud... Overall I am happy with the result.
