a ported box is better i have tried a sealed as well as ported and the ported dilivers far more power
I would suggest if possible listen to the 2 different subs then make decision
well if your going to put them in the trunk any it just depends on how big the enclosure is measure your trunk find a enclosure you like and measure it but with a cavalier id say drop 10s or 12s in thats all you really need as for door speakers or rear speakers the fronts are 4x6 and the rear are 6x9
10
The simplified expression is 40 - 12s
101

12s
