Is it possible to put two 12's in the back of a '95 Ford Probe and still have good

[Vincent]

sound coming out? I have a '95 Ford Probe and I want to put two 12's in the back. I also want to have the cover to lay flat just to cover them up. Even though it is a small hatchback, I still want to have some room in the back for a duffel bag or two just in case i decide to take a trip
