how do those 8's sound in limited volume enclosures?
what do you mean limited volume

the cadences require about .75 cf each ported

and the fosgates about the same

cadences get really loud at rated power and sound ok doing it but the rockfords sound super clean

 
working with .65 per chamber sealed

Specifications

Recommended Sealed Box Volume: The sealed box volume range recommended by Rockford Fosgate is 0.1cu/ft to 0.5 cu/ft. Within this range, the ideal size recommended by Rockford Fosgate is 0.3 cu/ft, so this is the enclosure recommended by Crutchfield.

Recommended Ported Box Volume: The ported box volume range recommended by Rockford Fosgate is 0.1cu/ft to 0.75 cu/ft. Within this range, the ideal size recommended by Rockford Fosgate is 0.625 cu/ft, so this is the enclosure recommended by Crutchfield. One 2.5" diameter x 11.25" long port should be used with a 0.625 cu/ft enclosure. This tunes the box to 35 Hz.

Power Handling: The woofer has two 2-ohm voice coils, and each coil can handle up to 125 watts RMS (250 watts peak).
