I have the equiliser in my HU. From 20HZ to 15000 hz.
I am not really sure how that would work.. And also what about all the other funcions such as time alingment and so on..
The other option is
2 subs in the back
8'' for midbass
either 6.5'' or 5.25'' for the midrange as a component set (with crossover and tweeter)
That is more simple way,and i would get it over with 3 pre outs,but first i want to see if the 5 way is possible,and how much of a hustle is there.
