Good choice. Back in my nooby days I asked the question about two 15s sealed or 1 15 ported and decided to stick with what i had used before, and it got loud but it just seemed like so much more was missing. I was seeing on youtube single 15 setups and it made me disappointed in my setup. Eventually got the new 15 in my car and it made a world of difference. Got much louder and much lower lol, wish I would have done it in the first place. Had like no roof flex whatsoever with the two 15s, but with the single I was able to do this
