150 is not a number to happen just by throwing a sub in your car and putting a lot of power to it. There is a ton of design that goes into hitting numbers like that...and as was stated, you won't get there if you asked this question, sorry.
For reference too, the sub isn't really that important, it is, but not...the install is much more a factor in what you hit. Type R's are fairly cheap drivers (though effective), and a few people on here hit over 150 last week I believe at MECA world finals...so, figure out if that was the best sub in the world or not, then realize that they were taking top 3 at the world finals with marks right around 150.
