50s from one sub isnt easy

True dat. Took me an 18" D1 BTL in an oversized box on my SAZ-4500 at half ohm. Did it at 39hz, but I didn't like the way the BTL sounded in my box.

Not saying it's impossible, but you're going to have a hard time getting 150 with the equipment you have now. A more realistic goal would probably be 144-145. Either way good luck and welcome to the forums.

I would recommend you start thinking about some things before you dig into the build.

#1 box orientation (sub up port up, sub up port forward, sub forward port up, sub forward port forward, sub up port side, etc). I don't have much experience with trucks, but a friend of mine has an 18" BTL sub up port up with 3 6" aero ports, it's doing 148.x @ 31 hz I believe, most pressure I've ever felt and I've sat in a few 153.x and 154.x cars.

#2 tuning. If you want to murder the lows, you probably won't be hitting a high number on the TL but it will sound better you'd want to tune around 28-33. If you are going for something still pretty musical with good numbers, I'd tune from 34-37. If you're not worried about how it sounds and just want a number, find the resonant frequency of your truck and tune about 5 hz lower.

#3 port area. Similar to tuning, if you want your sub to sound really good, opt for less port area. Something like 10-12 in^2 per. If you want something inbetween that'll still sound pretty good but also put up decent numbers, use 14-16 in^2 per. If you're just going for a far box and numbers, go 18-25 in^2 per.

Take this info as my personal opinion based on what I've learned from a lot of the local sounds people and through some personal experience. If I was you, I would probably tune to like 28 with 10-11 per and just murder the low end. But then again that's my preference.

ill say it. you wont get to 150db with that sub off 1500w in a truck. i dont mean to offend, just making sure you dont get your hopes up.

If I answered you in a well mannered, informative way, you asked a good question or had a good attitude. If I was an asshole, you asked a stupid question or you had a fucktard attitude... or I was in a bad mood.

I can see it being done, but it would take a lot of building and rebuilding of boxes. It would have to be a strictly fart box and he'd have to tweak a LOT of things, but I think it would be possible. But to get that number on something that sounds good, I agree it's not going to happen with what he has now. Maybe if he doubled up on cone area and power.

ya, it would need to be tuned over 50hz to have any chance.
