Since what I listen to most is alternative rock and speed metal I don’t require a huge sub woofer, what I require is to isolate the low frequency signal. The JVC KWAV61BT allows precisely for that.

I installed it on my 2013 Versa, it is placed on the passenger side below the glove box area. It doesn’t draw much current so I tapped from a spare 20 amp acc fuse.
Sounds great for alternative rock and speed metal. Here’s a sample:
