That a very subjective question. There is a lot of factors to determine "how that would sound". But if its done right, it will be very loud if thats what you are looking for. Why are there 2 posts of the same thing. No bueno dude. I don't know why it's up their twice. My bad I didn't mean to post it twice. I guess I should have asked if The fi btl and the sundown 1500 are going to work well together. Like is the sundown 1500 powerfull enough for the btl?
