This is about saving trunk space in another car. I'm running about 9.5cu/ft in my Suv. I know ported is louder. So I guess I won't be getting the R's. Xprime how mant watts did you run on the 1.3 sealed? I'm pretty sure the P3 or the RSDc is a lot less power hungry than the R. Any comments on the P3 vs. RSDc sealed? I asked this question because there are some reviews out there saying their R is loud on 400-500 rms, and that you don't need 750-1000 rms. I just need something that's a little above a CVR. I can't really find that many reviews on the Phoenix Gold RSDc?
