will box (freq) be lower if i pull the subs out and go motors up

[fecupe2001]

See?? SMD forum it´s awesome!! hehe, i changed all the wiring when i inverted the subs, didn´t know you don´t have to anything else

if you have 4 18's and each one is .25 cubes of displacement, you will gain an entire cube which SHOULD lower your tuning...it all depends on what your box sounded like before or what the specs were though - you just have to try.

as for phasing you dont have to change anything. The signal is A/C so it makes no difference as long as all the subs are wired the SAME. If you have 2 inverted and 2 NOT inverted (or something like that) then you would need to flip the wires on just two.

thanks meade,,,message me if you ever get time,got some very important issues i need help with..and thanks to all
