This is awsome! It takes up no space and drops low enough to give you proper smooth deep bass that's detailed due to its slotted port. You'll need a 300w rms amp to power it too. My amps fitted on top of my spare wheel out the way. I have a remote switch for my amp so I can turn the rear sub off while leaving the original under seat sub on. Doing this highlights the difference the extra sub makes and how much sound your actually missing! My 12" sub is great but only running at about 35% as it can go very very loud and very deep. The 8" jl audio has more than enough proper subsonic low end for your average UK CR-V owner and I highly recommend it if you'd like to improve your sound. I still need to buy some front speakers so I'll let you know what I think when I buy some. Any recommendations appretiated.
