One is in my sig with 2 6in pvc tubes tuned at 32hz..other is bigger at 6 1/2cu square port at 32.first one at 5 cu and sounded better...I had a jl 15w3v2 that could hairtrick my back hair and this fi sounds and performs so far likle my 12w7..hell I think my boston g512 was better.I think its the sub up port back setup that's doing it in my jeep..always sounds better likbetter with both back

what do you wire it to? its D1 so i am thinking you are wiring it to 2 and with imp rise and what not you are coming in high 2's low 3's.. with that amp you are only putting about 900 to it at that.. FYI it wants all 2000
