    I got this little guy and am really happy with it.

    I got it its own amp mounted under the passenger seat. It sounds really clean. Enough bass to make a difference to your music without annoying the crap out of the neighbors.

    I believe, by noting the reference to free-air setup, that he wants a direct factory replacement, factory location, factory fit. I'm not currently in the market to change my stereo, but when I do, I want the same. I cannot and will not give up trunk space....

    Ah gotcha. I thought OP wanted a non-sealed or ported box when he said open-air. Now I know.
    Haven't seen too many people have much luck with replacement of the stock speaker. Maybe it's a weird size? Or maybe I've just been looking in all the wrong places...

    There is nothing that will drop in to replace it and have any real effect or sound good, size is the main factor as you don't see many IB/free Air subs below a 10 as you need a rather stiff suspension to control the cone. you could use an 8 designed for sealed (needs a higher QTS above 0.45 to sound best IB) but there are not a ton of really good ones for a free air out there.

    Sound great, made well. Installed in a 2015 Civic SI in the back deck. Said it would fit but I had to modify the hole opening and Trunk lid springs for clearance. Magnet is much larger than factory and the springs caught on it. Also had to remove the child seat anchor point to get it to fit in the hole.

    I think I'm going to do this in the near future. Funny that you should bump this post. Literally was just thinking about it earlier this week.
