I just got done setting my gains with the DMM, my main issue and area of concern is the subwoofer and the Hifonics Bxi1606d amplifier. The component set is working and sounding fine and so is the Sundown SAX 100.2 amplifier. The Hifonics amplifier and subwoofer on the other hand are just being a
pain in the *** to get sounding decent.
To give you all the information I can on the subject we'll start here. I want that 15" Fi Q sound that we see and hear in videos, the smooth rumbling bass on all frequencies, well-reproduced, very loud, and sounding very good. To achieve this I have done the following.
I had the following set on my amplifier and head unit.
Amplifier:
SSF: 25hz
LPF: 80hz
Phase: 0
Bass EQ: 0
Bass Boost: 0
Gains: Adjusted with a DMM at their peak playing frequency to do 34.6volts(1200watts@1-Ohm)
Noted with a DMM, the impedance load on the amplifier is shown to be 1.5ohm's according to the DMM staggering at 1.3ohms every now or then. The DC voltage being sent to the amplifier is steady at 14.4volts.
Headunit:
Subwoofer Output = 15/15
Volume: 26/35
Volume Offset: 0
Loudness: Off
Crossover Frequencies For The Subwoofer is
60hz with a -12db/octave slope.

I decided to use this song as a test song, "Put On" - Young Jeezy.
Well that, yielded no real decent results, the subwoofer sounded fine with no clipping and no distortion but also wasn't very loud at all. Heres a video of it.

We will name that as the default setup, no enhancements, just pure gain and frequency tweaking. Shortly after that I decided max out the filter settings on the amplifier, setting the Sub-Sonic Filter at 15hz and the LPF at 250hz. And let the cross over settings on the head unit take over. There was a distinct increase in sound and performance from doing this, but nothing too great.
So a little satisfied with that but still not impressed I decided to play a game to see how to achieve that 'sound" that I defined above and by doing this I played around eight different setups and recorded them with a video camera so you can see the performance too.
