Maybe you should shake your cane at yourself :dance:
Adding a sub to the frunk is an exercise in futility, but nothing ventured, nothing gained

I like a good car stereo, its I just don't like listening to someone else's car when I am in mine, or worse feeling some thumping from another car when they are stopped at a light next to me or when they drive by

All seriousness aside

Add a sub to the passenger seat area. They are several threads about this

BTW, how is that Lanzar SNV695B? Looks pretty good, especially for the price.
Is the NAV any good?
