lower all levels to minimum and adjust from there...unfortunately there isn't a lot we can do from here. You've been to 2 pro shops and they haven't tuned it to your liking with the car there, I'm not sure how much we can help without hearing it. It's hard to understand how the bass can be so overwhelming with one sub in that set up with the power you're giving it. If the amp's gains are reduced to minimum, bass boost eq's are turned off or minimized and bass level control is minimized...i can't see how there can be so much bass...maybe our opinions of too much bass is very different????

I really think your crossover is just set too low. Check the crossover on your deck and amplifier and tell us what they are at. Some can have crossover settings as low as 60hz for decks, and lower for amps, because it's a dial.A 12" should be able to be punchy, or something in the equation is wrong.

Is there a sub-sonic filter on the amplifier? If so, is it being used?
According to the amp specs, there is a subsonic filter. 30Hz, at 12db/octave. Make sure that you're using this. It may clean things up a bit for you.

if i take a picture of my current set up, and post it, would it help? I really wish you guys can hear it, and no, it's not me, all my friends say the same thing about the sound. any of you guys live in toronto, i feel like i have more hope here than anywhere else...

here's how's configured:
head unit setting:
AMP setting:
Gain is set at 3/4 of the way, and bass boost is turned off (recommended), and sub sonic filter is on
Re-Q
top row "LF" "RF" does not apply since those are for speakers.
Sub setting on the Re-Q is slightly above half.
Sub Sonic Cross over (SS) is turned on to max
Low Pass Cross over (LP) is turned about 3/4 of the way.
This is how the sub box look (picture taken before I put the actual sub in)
Hope this will give you guys a better look at how my systems is set up.
Really appreciate all the responses here!!

For starters, I would suggest turning the gain all the way down, counter-clockwise. You're using the remote gain too, that should be minimized as well, to start.
Your LPF starts at 40Hz and finishes at 200Hz - seeing as the dial is at the 9 o'clock position, you filter is set at approximately 65Hz, which is pretty low. If the dial was facing straight upwards, it'd be set at 120Hz. I would set the dial at the line on the top-left, it'll be at 93.33Hz. Since your filter slope is a steep 24dB/Octave, you could probably get away with it set there, as the higher frequencies will be getting cut off pretty quickly.
At first glance it appears that you have a narrow band of low amplified frequencies that are being driven harder because the gain is set fairly high.
As for the Re-Q, I'm of no use. I've never seen one before...

Are we missing something here? You're complaining about too much bass, yet you have the bass eq on your head unit turned up above 0...turn it down! Start from scratch:
1. head unit---all levels at 0, dsp off
2. amplifier gain at minimum (lowest output), cross over at 80hz (use the manual to figure it out), subsonic on, bass boost at lowest level.
3. re-q---follow manual for proper set up
once all that is done, then:
1. set volume control on head unit at about 70% or at the level you listen to it most frequently.
2. adjust the amp gain first until you get a good blend of bass output with the rest of the music
3. now adjust the crossover to the point you feel it sounds best to you
4. you should have the right amount of bass in the range you want now
5. play with the other controls to fine tune the sound or adjust for taste or music type
that should sound much better.

Yup, looks like your crossover (labelled as FREQ) is set way too low. Turn it up right where Tragic says and you'll be flying. Too much low end bass would definately be an issue with the crossover turned that low, I'm surprised noone else caught it with all this other stuff going on.

Isn't this Re-Q unit between your head-unit and your amp? Wouldn't it then be set to "before amp"? The reason you had it installed was to improve the bass signal being sent into the MTX amp.
Like I said, I don't know anything about the unit, but that's jumping out at me right now.
Earlier replies to this thread state that a common problem with factory source units is that the bass level isn't elevated equally as the volume increases. Wouldn't that result in an apparent lack of bass? If nothing was used to make a flatter source signal, then he'd lack bass. Now, the Re-Q was suggested, but his problem was too much bass. I still think his amp wasn't set properly.
