btl setup

[t-rust 0]

i am new to FI audio and ive been searching and watching videos. i have become very interested in this brand now. i want to probably just get one of the new 18" btl's and i didn't know what options to get for this sub. it will be used daily but i still want to know how many db's this thing will put out with just having one of them. and also what is the best amp for one? thanks
