I could EASILY build a vehicle in the mid 50's maybe even 60's for less then half that. :-/ My old Ram did a 147 at 28Hz with 2k and a shitty wall...... He won't listen. because I am listening to a wide group of people on a wide range of forums, not four know it alls. Out of every 10 people, I get one or two saying they can do it with two 10's and $2k the other 9 say its extremely difficult even with 20k and testing retesting so if youre tired of repeating yourself, please, just move on. I still say thank you, I know youre trying to help, I know youre blue in the face, but youre the minority making it sound easier than everyone else is saying. maybe 9 in 10 are stupid and you are the 1 in 10 that has it fugured out. why dont you cut me as a loss? Maybe you should at least analyze that 10/10 people that see your wasted efforts suggest going with subs that AREN'T for IB. but thats the point: I break all of their stupid rules, and they are too busy thinking they are always right and hatin cuz I proved them wrong dont tune below 30Hz for music, dont tune below 30Hz in a car, dont use IB drivers in an enclosure, sure as hell dont port them, sure as sure as sure as hell dont port IB drivers in a car below 30Hz for music, dont give IB drivers rated 550watts 3KW while ported below 30hz in a car for music, dont put your front stage in your roof, dont use expanding foam or duct tape, dont flip your kid off, dont get your alt tested, just dont cuz we say cant and if u do we will call u names and carry on and on and on like we know a thing or two Last time I heard you blew the subs and you don't have properly staged front line.
