sub box help

[chaz11487]

i have 2 jensens w/ a 1400w amp and 2 jlaudio's w/ a 1000w amp. i have them in the back of an f-150 and the jensens are in a sealed box and the jl's are in a seperate sealed box. my ? is when all are on it doesnt sound as loud as when just the jensens are on.

Well first, you shouldnt mix subs (ie different brands, sizes, models, etc). Which amps are those? And what kind of boxes are they in?
