I need speakers for a 1997 crown Victoria front and back

I recommend getting some speakers

Are they like a box to make bass better?

I do feel like the bass is more solid and better and eliminates the "boxy" sound that the door enclosure normally produces. I think it eliminates undesirable resonances that distord the clarity of the sound. If I had to chose, I would install them again. One warning, they come in different sizes and you may need to cut them to fit your door cavity. When I cut the first baffle, it was a bit lose and then it produced an undesired vibration between the plastic of the cavity and the foam baffle where they were both surfaces were barely touching. To correct this, I cut the next baffles in a way that they fitted tighter in the cavity and eliminated the noise produced by the vibration.

In some vehicles where the speakers mount on a middle steel panel and the whole shebang is then pressed against a speaker grill molded into the inner upholstered door panel, check the clearance carefully, as it varies a lot and this little thing can add enough to make a firm panel fitment a bit difficult at that corner. You can always trim the plastic grille area. This is rare, but might be important.

Would I / should I use these if I am mounting the speakers in individual cans?

I've noticed less pronounced lower frequencies, which is ok for me in trade-off as I use it to combat damging effects of water leakage from a bad window seal. If by 'can' you mean a designated enclosure; I would skip this and line with polyfill if anything. In a bare door cavity you should expect achieve cancellation of the reverb from highs and mids bouncing off metal. These are essentially 'individual cans'.

Beste Erfindung seit es Car Hifi gibt

Die Boom Mat passt super in die Türen meines Fahrzeugs, habe den Boden abgeschnitten, damit das Türvolumen als Bass Resonanzkörper weiterhin genutzt wird. So sind meine nicht so ganz billigen Türlausprecher sehr gut vor Wasser das von oben in jeder Fahrzeugtür runter tropft geschützt und auch wenn man mal in die Waschanlagt fährt ist die Boom Mat immer noch der beste Nässeschutz und erspart den Kauf neuer Lautsprecher. Bin zufrieden mit dem Top-Produkt, kann es jeden nur weiter empfehlen der vor hat sehr hochqualitative Türlautsprecher zu verbauen, so muss er auch die Waschanlage und Tagelangen Regen oder langsam abschmelzendes Schneewasser nicht mehr um seine Türlautsprecher fürchten muss. Das das Wechseln der Originaltürlautsprecher auf z.B Türlausprecher von Hertz oder von Audio System, ein "echtes Wunder" bewirken, muss ich nicht näher erklären, liegt an der Elektronik der Weiche und der Qualität des Chassis und des Hochtöners, das wissen die Car Hifi Insider eh schon alle. :-)
