If you can help it would be most appreciated.
Thanks Barney Nel Westrand.
MOST OF THE TIME U WANT UR AMP RUNNING UR SUBS TO MAKE THE SUBS SOUND REALLY DEEP AND HITE REALLY HARD BUT BE CARFULL WITH THE BASS BOOST IT CAN BE TO HIGH AND CAN BLOW UR SUBS, NOW WITH UR AMP RUNNING UR MIDS U DONT WANT A LOT OF BASS MAYBE NOT AT ALL CAUSE UR SUBS WILL HANDLE THAT, SO U WANT A LOT OF TREBLE WHICH SHOULD BE THE LPF, O AND ANY WHERE FROM 6DB-12DB WILL BE GOOD.

is the difference between bi-wiring and bi-amping?
Bi-wiring is using the same power source (amplifier) but
connecting that power source to a woofer and a
midrange/tweeter on a
Bi-amping is using two separate power sources (amplifiers)
connecting one amplifier to a woofer and the other amplifier
midrange/tweeter on a speaker.
How do I bi-wire?
Your speaker must have two separate positive and negative
connections (one set for the woofer and one set for the
midrange/tweeter). Connect one wire between the positive

its not a subwoofer it is a midrange speaker. all you do is connect your outputs from the radio to the crossover then connect both the tweeter and midrange to the outputs on the crossover. it is called a component set.
If there's no sound at all from the subs and you know they are good, there's probably no output from the amp. It's either wired incorrectly or it is defective.
If there's some sound but just not loud enough, then either the amp is not getting enough of an input signal from your head unit, or the amp settings are not adjusted properly. Adjust the crossover and gains for the best output to subs. LP filter on, crossover frequency at about 80-100Hz, and gain to maximum without distortion when head unit volume is at about 3/4 maximum.
An active crossover is needed if you plan to do a 2.1 or 4.1 or 5.1 setup.
Check if you have a subwoofer output from your head unit (most later models have). If there is, you might not need an active crossover anymore, but it depends on how you like the sound quality of the separations (low, mid, high). Please note the speaker polarities too.
