Weak bass and midbass from preamps?
I've been messing with this setup off and on for months now and I can't seem to get sufficient bass and midbass from my Eclipse components. It all just sounds hollow because the 80-300Hz range (rough guess) is very quiet. They sound alright if I turn the sub off and crank the "bass" setting on my HU to +8 at 80Hz. Obviously I can't do that when my sub is turned on though.
Today I hooked up an ancient Rockford Fosgate 2 channel amp to one of my components and with the "bass" knob all the way down things sounded the same as on my Kicker amp. When I turned the bass knob up half way it sounded perfect. I would do this with my Kicker amp but the bass boost is tuned to 40Hz so it doesn't do much for the components, even when I turn it all the way up.
So I'm wondering... is something wrong with my HU since I clearly need to boost the bass externally? Or is it normal to need external processing to get good bass and midbass from components? Should I just get a cheap EQ and be done with it? I'd use the RF amp but its old and beat to hell and I'd rather not waste the $90 I spent on my Kicker amp 6 months ago.
Just for some more info:
I'm almost positive that it isn't related to sound pressure in the doors because they are very well sealed and I've tested speakers in free-air and they sound fine with the bass turned up.
Also, my stock rear door speakers are still powered by the HU and I normally just fade them out since they sound pretty harsh. They do have plenty of bass though, which is why I think its related to the preamps.
