Default Midrange Problems

Hello everyone, my sound system consists of:
Eclipse AVX2494 Headunit with line out converter
Eclipse 75x4 channel amplifier
Eclipse mono amp
Eclipse SC8264 2 way component speakers
Eclipse 3 way coaxial speakers
Eclipse 10 inch subwoofer

I am not sure if it is just the nature of the speakers, but I feel like I am not hearing the midrange enough. For some songs, it sounds as if I am only hearing the extreme highs and extreme lows. I know it's a bad description, but the sound does not sound "full." Music genres like rap sound fine as they have alot of highs and lows, but some of my other music sounds off. I have tried adjusting the settings on my amp for a while now and not much has improved. Anybody know what might be wrong?
Thanks in advance

dont know what to say. Not there to hear it. All I can say is mess with your EQ until it is the way you like it.

First two things to do.

Reduce the gains on your subwoofer amplifier and set the crossover frequency to a lower number .. try 50 or 60Hz

Change the setting on the crossover from the Eclipse components. There should be a -3dB setting .. you might have to flick a switch or change a jumper or soemthing inide the XO.

Good luck

Thanks Jim, I'll give it a try. Right now, the crossover for the components are at 0 db.

Also check your polarity - that the + is to + and the - to the - on both speakers. If they're backwards they'll cancel each other out.

What do you mean by cancel each other out? Does that mean no sound? I hear sound coming from all the speakers. Sorry for my confusion

Good point Paul ... actually a common mistake in this industry

Its basically like two waves summing when one wave is at +1 and the other is at -1 ... you get a total of zero because they are out of phase. Sound propagtes in waves ... so having them in the same "order" or polarity is the only wave to get "constructive" interference betweeen the two, resulting in a full, coherent sound.
