Resonant frequency question.

[juicemanfta]

What does the resonant frequency of a vehicle has to do when you are designing your system? I am planning on putting 2 15” HX2 rated at 1000W RMS each in a ford explorer what would be the best tuned frequency box for these? Also I am going to power them each with 1150W RMS would this be bad for them? Is it safer to over power them in a seal box?

BTW i am going for SQ.

if you don't compete then there's no real reason to go through the sweeps needed to determine the resonant freq. ... thats for the extremely competitive world of competitions in my opinion

what you need is a box designed around your subs exact specs.

For a SQ setup, you care more about the midbass hump (phasing issue) and the midrange suckout (also a phasing issue) than about what frequency your bass peaks at. Tuning you want to match to what the sub wants for proper response and will have nothing to do with the peak frequency of the vehicle either.

6 cubes tuned to 33 - 35 hz for the pair, iirc.
