Re Mt 12" low output
Ok guys I really need your help.
I am really confused and dont know what to do.
Thanks to teamaerostar2 he told me to come here and you guys would be able to help me out alittle.
I have a 1998 neon first off.
Electrical
300amp alt
2 runs of 1/0 gage power and ground
2 Yellow tops
ect....
Amp for sub
Orion 2500d wired at 0.8ohms solid 2500w rms.
Sub
12" Re Mt dual 1.4ohms coils
Box
3 cuft after sub and port displacement
50 square inches of port area
Tuned to 35hz
Braced with 3/4 thread rod
Now my problem is that For what I got the output is not very good.
136.3 db on the Tl.
Can anyone help me out here? I know my system is capable of hitting high 140's so what am I doing wrong.
Here are all the setting on my amp and deck.
Head unit turned up to 45/63
Sub control all the way up.
Eq set to flat
Xover for sub set at 80hz
Loudness off
Amp settings
lpf 80hz 12db slope
Hpf 30hz
Intelli q set to 0
Gain set at 44.7v 0db 60hz test tone
Gain switch set on gain.
So any suggestions please dont hesitate to post.
I am out of ideas.

I would say play with the port and your frequency when you burp it

Never played a 60hz tone.
That is the tone I used to set my gain.
Used a 35-60hz sweep.

Yeah not out of phase checked it with a dmm and it reads 0.8ohms

My deck just allows me to set it at normal or inverted and it is set to normal.
