I have recently purchased two Clarion PFW-1051s. I have a 2004 e/c chevy and I'm building a box under the back bench for both subs and the amps. The subs are going to be firing down towards the floor in seperate boxes. Now my problem is that I cannot seem to find the recommended air space for these particular subs. They are still in the mail right now so I'm hoping that this information will be in the manual. Is the RAS not posted anywhere because these subs are shallow mount and Clarion just assumes that the box will be small? I don't have a whole lot of room so i was wondering if I should just make the box as big as possible or try to find out the exact numbers and build to them? My other question was about how high to have the subs off the floor? Any suggestions would be appreciated. Thanks.

From what I can gather so far about those Clarion shallow mount subs..is 0.5^3...or, half a cubic foot per sub..sealed.
Do not just assume to build the enclosure as large as possible as besides sounding like crap..it could contribute the the subs shredding apart..(the suspension construction and parameters of the sub takes airspace into account).
I have built quite a few firing down boxes in pickups...4'' to 6'' off the floor will work fine.
I know the speakers do come with a decent enclosure chart but I can't locate one. The only other option if no one else can post it is to wait until the subs arrive...but they have been tested in .5 sealed and work well.
