[QUOTE="mannyt, post: 404767, member: 553672"] -The crossovers i am using for the fronts have the correct frequency crossover points and have a slope for 12dB/octave. I used an oscilloscope to design and construct the zobel network for phase correction. I have HPF on the fronts at 55Hz ( i know this is pretty low) and they haven't bottomed out. So would i see a significant inprovement in the sound if i had the crossovers professionally made? -The 6x9's are left over from when i had no subs. i found they were drawing the soundstage too far back. so i constructed a LPF @ 7khz with a 3dB/octave roll off. -The only spare 5 1/4" drivers i have unused is some alpine type S co-axial drivers.... i really dont feel these good enough though. -I do have a spare 8" kicker solobaric driver should i try to find another one for the other door? or would a 4ohm vifa driver be better -The head unit is ok... for low volume work. but when you crank it it distorts substantially. i have connected my discman up to my amp through the line driver and it was substantially louder and sonically better.
