this is my system i got. they are 2 10" kicker L7's a hifonics 1600watt amp and a custom made and painted fiberglass box.
this still isnt all the way up. amp was at 3/4ths. my car doesnt flex so much. im guessing cuz the box is sealed and because how small my car is. its a 1991 plymouth laser. but yea the interior of my car rattles. my dash, my steering wheel, everything. and i forgot to set my phone on the hood and trunck in the vid. but my camera died during this vid rite as a changed the song. o well.
enjoy those of you who said it sucks. my first vid was with the bass all the way down on the head unit. which was -8. in this vid it was at 0. it goes to +8 but i dont like it that high. this is a much better vid.
