These are monsters , sounds great hits the lows . The worst part is getting or finding enclosures they like big airspace
One issues I’ve ran into was the cuts are odd compared to the other L7 subs . And the specs from kicker don’t talk about the corners of cut out . I started out with one sub and switched to 2 subs . 2 dif builders and the 2nd. Had a cut out issues so have to rebuild . That would be my biggest issues . Being so diff with out proper info on getting a cut out . My builder almost 2 hrs away so he didn’t have my temple from the shipping box from kicker and he went off there specs and it didn’t give all the info needed
