Sound Wonderful. Excellence as expected from infinity. Got mine on a SKAR 75.4 amp. They rock. Solid bass and crystal clear highs.

Best sounding 6X8's I've ever owned. I have them paired two a Kenwood excelon 795bh receiver and there very loud. Very punchy in the midrange and exceptional Bass. Infinity The name says it All.....
