Thanks for your advise. It seems like tuning the sub is much easier than
tuning the amp for front speakers.

you can either run your crossovers off your hu or amps if your hu has them
so set your crossovers at like 80 high and low for start
then put all the faders sound into the front speakers turn the gain on
your
amp to them almost off- turn your speakers way up as loud as you can
clean-
now increase the gain slowly to them until you get to distortion then back
off the volume a bit and leave your gain set there

on the sub assuming you are within safe power range to it what I do is
turn
on some good dynamic music or a sampler disc and adjust the gain till it
fills in the void for my speakers and fills the car with bass to my taste

the tuning such as bass emphasis treble accentuation and soundstage
effects
are a matter of taste and pref. but you should make sure the gain is
correct
for your speakers. hope this helps

Originally, i have one power amp (50W X 4) to drive my front and rear
speakers and one (50W X 2) which was briged to drive my 10" tube
subwoofer.
Not too satisfied with the bass which i could not hear at low volume, i
changed the power amp to 150W X 2 bridged and changed the tube sub to
15"
sub in a customised box.
Now, i am quite satisfied with the bass at ALL volumes!!
The problem is, i did not tune anything in the new power amp. The volume
and
crossover knob are at factory preset, i.e., at the center. Can anyone
please
advise me how to fully maximise my new power amp and new sub? Do i need
to
tune the other power amp which drive the front and rear speakers too?
Thanks.
