the SW output on your HU should be all the way up when setting the gain.
32hz tone probably wont even get you to the 38.72v your trying to reach. stick with the 50hz or go to like 65hz @ 0db. i think i actually used 70hz @ 0db.
shit so i guess i have to re do them tomorrow i have the sw output all the way up now it sounds good i think it could sound better tho ill try to re set them tomorrow with a 70 hz tone, whats the difference with freqs anyway like difference between using 50hz ans 70hz
You said they were louder when running at 4 ohms but now you re wired them to 1 ohm? I would double check and make sure you didn't wire one out of phase.
Also, I would tune it with the SUB Level at 1/2 (7 or 8) Not at full, I think it gives you better control between tracks.
Bass at 0 (always)
Loud OFF
SLA at 0 (if the deck has it)
I would put center freq at 60 if you can and use a narrow to mid setting (if it has it)
Turn off the filters on the deck as well...only use the one on the amp
