[QUOTE="Chrisrizzy, post: 8521887, member: 670926"] So I put in an Infinity Kappa 120.9w in my 07 Acura TL a little over a week ago and it just isn't sounding as good as I expected. I've heard nothing but good things about it, too. It's in a Belva 1.0 cuft sealed box (recommended volume by Infinity) with some poly fill which I guess makes it 0.1-0.2 cuft bigger. The amp is a Rockford Fosgate R500X1D. Cheaper amp, but it puts out a good 500w. Previous set up was with 2 12" Rockford Fosgate P1 subs in a ported box. The Kappa still can get loud, but certain songs definitely don't have as much bass and I expect that with sealed. The Kappa plays rock and anything with natural bass quite well, but a fair number of rap and electronic songs lack the SQ I am expecting. The ski pass in my car is open to let more bass in the cabin because I want it reasonably loud. With it open the bass can get all boomy and crappy sounding which I don't understand as you can have a truck or hatch with a sealed box and still get tight bass.
