I just got a new install. I have a '99 Civic EX with a factory HU and stock 6 1/2" door speakers. I just put in a pair of MTX 6X9 triaxials in the back deck. I am driving the 6 1/2's and 6X9's with a SoundStream MC120 (Hey! It was free!). I also have a MTX Thunder6152 amp driving a MTX T410X3 10" TriSub box.

It bumps, but it sound like ass above the low volume. I can't turn the bass knob up above centered without over-driving the 6 X 9's and no matter the setting, I lose all clarity on the mid-range above half volume.

There is no gain control, or any control, for that matter, on the MC120.

I want to keep the volume but clean up the sound. I am new at this and would apprecate any ideas for cleaning it up.
