Two x15's.. Am I expecting too much ?

You could be clipping. Even at 1/4 gain

Sub on hu should be at 0

Depends on the HU but definitely some dirty power getting to those coils. Find HU clipping point and reset gain on amp correctly.

Like he said depends on the HU I have my sub level up. So find you HU clipping point and reset gains.

Look on the tool map here and see if there is anyone near you that has an DD-1 or O-scope and see if they can help you out.

Geez I'm old I guess.. not sure what tool map is

it is a map of people with tools and their locations to help you with what you need... and they list what they accept as payment.... ie... lunch, $5 borrow your girlfriend... ect....for example there is a guy in my area that will let you use his dd1 and compensation is lunch

Agreed to set gains correctly as all have said.

In addition, i'd try turning your subsonic filter down...assuming you have a decent box for those subs, you probably have no need to run the subsonic at all.

To answer your question about gain setting on the amp, you could definitely be clipping. Due to the fact that your head unit puts out so much voltage, it doesn't take much of a turn on the gain knob to match that voltage. Does that make sense?

Im not the one you want to try to troll. Just a fyi for you.
