I'm getting a new Fit Sport and considering that its the premium sound i was just going to upgrade by intergrating a sub into it, problem is, i am picky. I dont want overpowering bass but i want to feel it, and it has to be clear. It will be a single sub setup of whatever size, since i have plenty of room *grand total of 41 cubes in the car*

Have at this, i want to do it right on the first try this time.....

Got it narrowed down to an RL-s 15 or a BTL 15, i just havent heard to much on the RL-s's and didnt know how the SQ of a BTL is, any input would be thankful

Those are really apples and oranges.

I dont want overpowering bass but i want to feel it, and it has to be clear.

Keeping that in mind, I'd go with the RL-s...

"Premium sound" or not, I'd bet that upgrading more than just adding a sub would give you some big benefits.

for some reason overpowering bass and RL-s 15" don't go hand in had for me.

Thats like trying to fit giant off road tires on a civic.

How about a Fi "Q" or a SI BM ?

Both good choices for what he's looking for as well.

If all you're doing is integrating a sub into the stock sound system, just throw a JL 10W6v2 and a 500W amp and you're good to go. If you go with a 15" and >1000W, the bass is going to completely drown out everything else.

ewww.....ive done more than my share of JL time.....and ive never heard of the SI BM

Never heard a W6 have you?

heard to many of them, never cared for the sound they produce

Was there something in particular that you didn't like about them? Knowing will be really helpful in narrowing down your choices.

price to quality ratio and for some reason i just dont like the sound of JL

I'm curious to know what turned you off to the W6v2's sound, throw the pricetag out the window for the moment.

I'd love to make a recommendation for a Fi Q, SI BM, or one of two dozen other higher-tier speakers, but I want to know what you're hearing first. Otherwise we could be barking up the wrong tree...

Just trying to save you money and time spent experimenting

So far my favorite bass came from my OEM which had a......for lack of a better term.......fat sounding bass, defined hits and never lost anything during a long bass note. If i can stick with that kind of bass i want to.
