Unsatisfying output from a 12" FI Q.

I didn't do the wiring of the sub. I had David [TeamPSI] do it, and he just left me with a single wire, so I'm sure he did it right.
What's the easiest way to check it to make sure? Or do I need to take the sub out?

check the ohm load with a dmm, qs should be able to get loud without a problem, have a feeling its at 4 ohms and not 1.

I'll go try that out. I have a fairly cheap DMM that I bought from Lowes. It does get the job done though //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif. Will report back in a few minutes.

0.8 / 0.9, so I think it was done correctly.

Any air leaks behind the mounting ring on the woofer?

Try facing it different directions, since you have a truck.

I don't believe so, I had David put the sub in when he built the box.

Don't think that it's really possible without a new box lol //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Maybe it's canceling itself out facing the roof.

sounds like a bad box to me, everyone i know whos had qs had always had good output from them

Could it be the amp?

The head unit I have doesn't have very good pre amp voltage, so the gain is probably pretty high. I'm not sure off the top of my head, I just set it off to wherever the amp would give about 1250-1300 watts.

The gain on my 4 channel amp was just about maxed for the fronts, and only gave me 70 RMS. [52/62 volume].

The amp is good!
