Infinity REF1000S Reference 10 Inch Low Profile Subwoofer with SSI (Selectable Smart Impedance)

Q: Can it be mounted face down on the rear dash in the trunk of a 2019 Honda Civic ?

Yes. Our Infinity REF1000S can be mounted face down on your rear dash, since it's a specially designed subwoofer that can be used in a free-air application or does not require installation in an enclosure. This product has a dimension of: Cutout Diameter or Length: 9 7/16" Bottom Mount Depth: 3 15/16" Top Mount Depth: 3 1/4" You'll have to measure the rear dash of your 2019 Honda Civic to see if the sub will fit.

Q: would these work ok in the door of a (2006) corvette? It would be a pseudo 'free-air' , with the window opening...

Yes. Our Infinity REF1000S is fit with the door of your vehicle.

Q: Is this a good speaker to replace in my rear deck of my caddilac xts

This is a speaker that Infinity claims does not need Subwoofer box to perform. I would NOT agree with them. I had to build a Speaker Box in order to get good BASS. I would not recommend this speaker if you plan on just mounting it on the rear deck.
