Well I just checked the phase again and it's hooked up the exact same way as it was before on the Sony, both blue speaker wires (blue being positive) are parallel in one positive and the other two speaker wires for negatives are parallel into a negative.
*Edit* Would a Hifonics HFi1000.1d hit harder? I have one sitting here that I was going to return but if this APSM-1500 amp is going to be so quiet...
It's too quiet because you set the gain with a 0 dB test tone. This was already pointed out and it seems you didn't take the advice seriously. You've robbed yourself of output by a) not using an attenuated test tone b) probably not turning the volume up high enough. Reset the gain using a -5 dB test tone. If that doesn't get you the output you want redo the gain with the volume bumped up a few clicks.

Again, I don't know where you got the impression that I didn't take the advice seriously. Just because suggestions were made doesn't mean the knowledge seeking stops there. I will be redoing the Gain later tonight, thanks? I will try out your suggestions, and post back with results.
You were probably running the sony bridged @ 4 ohm which would get a good amount of power (6-700w) on the ****** 2 channel, running the AP at 4 ohm mono isnt taking advantage of 1/4 the power its capable of.
The Sony bridged is only rated at 340w RMS @ 4ohm.
Also I did a 50hz at -5dB track and redid the gain. I was shooting for 40v AC because I have two 200 RMS subs but the closest I could get was like 40.1-40.2, is that fine? The thing is super touchy.
I did it based on volume 40 (80% of HU volume), and at volume 37 A Milli now sounds way louder than last night when I originally did the gain. It now shakes my seatbelt and stuff. So I'm definitely pleased. My batt is about 14v with everything off, and on full tilt (39-40 volume) it drops to 13.5 at the very lowest. So on stock electrical I have no more dimming like before.
Anyway about the voltage thing, is 40.2 fine?
Thanks in advance.
