ok i have 2 ab xfl 1244 on a hifonics 3000D probably only puttin around 1000 into each sub. my box is pre fab and i want to make one myself but i cannot find any measurments online or anything for these subs. few local car shops want over $350 to make one lol.. but before i go and make one.. i been runnin these subs in this pre fab 1.75 each enclosure they sounded alright at first but def not what there made to sound like. now their starting to sound kind of crappy. i dont think the subs are goin i think the box is just blowing apart. but they dont sound right anymore. these subs able to be brought back to life if i make a box built to spec for them? or am i goin to waste my time since ive ran these subs in a prefab for about a year. even tho ive probably only hit 1000 watts into each one. and if you guys know the box specs or any other links or anyoe else whos built a box for these things lemme know..
a buddy has a camaro with 2 of these running off a ab amp and its insane.. the bass is so clear and hard hitting everything that i see shakes violently i couldnt even tell what kind of cart was drivin down the road at us.
