im doing a 4th order bandpass for 4 kicker l7s with about 1800 watts rms maybe 6th order if i can nail it

The mere fact that you're thinking about it and aren't confident almost definitely tells me it'll sound like shit. Go ported, bandpass is almost never worth the trouble.

i donno bout that ive heard u could just give them each 3 cuft and and port to 37hz it would get loud but i still think bandpass is the way to go get some one reputable to do a design .designing bandpass is hard but its not impossible for some one who knows what thye are doing i say go bandpass
