[QUOTE="d_sinsley, post: 8170579, member: 658010"] Ok I am a newbie, well not really but its been to long. I am building a Sub/amp package for my daughters car. First the parameters. The car needs a complete upgrade of the entire sound system so money on this is a big issue. We are starting with a basic system that will sound good and if she desires allows for upgrades over time. Space is also an issue. One major design consideration is that she/I want to use a 1/2" plexiglass front on the box and put purple lighting effects in the box.She listens to a wide variety of music only some of which is bass intensive. She thinks the basic stock system in my HHR with no sub and four 6.75's sounds great. So this will be an entry level system. I have in the past been a Rockford Fosgate fan. So Here is the deal. I am looking at the Prime series subs and trying to determine between a 10" 4ohm or a 12" 4 ohm. I have an amp (4 OHM when bridged) already that puts out 140W RMS and 300 W max which is right in these subs wheelhouse. Both fit in very small sealed enclosures. I have a little room to work with but .75 ft3 fits nicely and is perfect for both subs. I think she will prefer the flatter response of a sealed box and will get enough bump to make her happy. The question is this, how much real world difference in bass and volume is there between the two especially in a sealed box? Per Fosgate, fs for the 10 is 24Hz and for the 12 is 22Hz. Spl for the 10 is 86 and for the 12 is 87. I know what each of these numbers mean on paper but not to real world sound. Being that these subs are being driven with very modest power sources it seems to me that they are near equivalent.
