makeshift speaker enclosure?

In my 2000 Buick Century, i had the premium Concert Sound II system or something like that. anyways, the speakers finally went kaput and i bought some 5 1/4 inch Kickers for the doors and 6x9 Alpine's in the rear. I noticed that the front doors have a special enclosure for the speakers but the rear speakers have their entire bottoms just staring into the trunk. If i taped and glued some stiff wood to the bottoms to seal it, would the bass be stronger or will it sound terrible? And if i filled the front enclosures a little Great Stuff foam on the bottom, would it do anything? 60 RMS is sent to all 4 speakers.

    If you were able to completely enclose each 6x9 in a small sealed box, you MIGHT notice a SLIGHT improvement in frequency response, but not bass extension. People do do it, but you can't just slap something together. I'd say it's certainly not worth your time if you're just going to wing it with a makeshift attempt. As for the fronts, it's tough to picture exactly what you've got going on. If they already have a sealed enclosure from the factory, filling it some with great foam would not be advisable. If you're curious, you could always just stuff something removable down in the enclosures just to test it out.

    probably not going to get any benefit.

    Smaller full range speakers are generally designed with free-air (technically infinite baffle) in mind.

    They'll work ok sealed, but you would likely lose low frequency performance, not gain it.

    Foam won't do much of anything, definitely won't help.
