Aftermarket Underseat Sub

[gunk007]

I currently have a 12" sub in the trunk of my 05 and would like to replace it with an underseat sub to free up some trunk space. I also have the OEM underseat sub (not hooked up) in my car. I would remove the OEM and replace it with an aftermarket.
Anyone have experience with these?
Thanks

Yeah, I looked into it quite a bit. They all suck. There's no room for anything with enough throw to give low frequency response that doesn't sound like crap. They mostly just vibrate when given substantial power more than they project sound. If you want your car to vibrate with the beat, underseat works. If you want to hear bass, you need more air to move around. I would argue that all car bass audio is crap, but best case at least is to give yourself the most airspace to work with. Trunk wins.

Thanks, That is what I expected to hear.
