I am pretty sure I have neither the room or the amp for 2 of the Qs but I am getting 2 of em for $260 :) If I did want to change amps and run 2 Q12s, how much air space would I need to do them justice in a sealed enclosure? I have started to consider using both after a day to think about it. Initially I was only going to use 1. So, I guess I have 3 questions :D

enclosure space for 2 sealed

enclosure space for 1 ported

enclosure space for 1 sealed

Thanks for any and all help

Oh, the car is my 2001 Trans Am, I kinda want to use the space available on top of the gas tank in the rear hatch and get my ttop space back. If not familiar with the hatch in a 4th gen f-body, check out page 2 of my cardomain site. I have a few pics there and could take some more if needed.

Thanks again

Cool, thanks fellas :)

We recommend using a sealed box in the neighborhood of .8-1.5 cubic feet of volume (after all displacements for those wondering). (I personally think that 1.2-1.3 cubic feet is optimal imo)

Ported box we recommend using 1.8-2.5 cubic feet @ 28-33Hz (I personally think that a 32hz tuning is optimal, and has the most output and is still the most musical daily driving). Use 12-16 square inches of vent area per cubic foot of volume.

So for 2, I just double these? I have to get home (I drive a truck) and take some measurements, but I am pretty sure I can do a sealed enclosure for both up on that ledge. :D 2.4-2.6 should be very doable. What kind of power would I need for both? Would a mono-block amp of 1000 watts be enough for both or need more?

Thanks for the heads up guys. Again, any help or suggestions is greatly appreciated.
