One main problem with this system will be the lack of Midbass punch. This is because the 4x6 plates cannot deliver solid MB performance and the sub crossover point may have to be adjusted to fill in some of the gap.
In most cases, a sub sounds great when crossed over at 75 - 100 Hz. In this case, you may have to go as high as 125 Hz. on the sub settings and adjust from there. If the sub sounds a bit too "honky", (Too much Midbass) some EQ tweaks are in order. Most of it depends on how you set up the HU and amp together. (Non-fading sub output or tapped off the rear channel RCA's in the HU)

I assume this is a wedge "truck box" design. Make sure there is sufficient room between the sub and the seat. Other than that, you may want to try a ported box.
It is hard to get deep bass in a single cab truck. There is little or no cabin gain, and what cabin gain you do get will be close to the 100Hz range. Basically the sound wave is out of the truck before it can make a quarter of its wavelength, even if it bounces around a bit in the truck first.
As Swez mentioned, the 100-125Hz crossover point may enhance the sound. Maybe too much, but before you turn the crossover back down if it is too much, try to mellow it out with your EQ. The range may sound good once the peaks are smoothed over.

first of all the recommended sealed enclosure internal volume is suggested to be 1.5 cu.ft by the manufacturer...
next.. what is the version of the sub u have.. i mean.. is it a SVC or a DVC , and what is the ohmage of the voice coils present...
something like this would be written in the manual supplied with the sub..... SVC:4, DVC: 2 or 8......
we also need to see if the sub is wired to the amp for a proper impedance to assure optimum performance...
what are the settings you have done on the amp...??
before that,,... what value fuses do u have on the amp... does this bazooka amp deliver what it promises..???
lot of things to consider before trying to tweak the sound and being unsuccessful....
Victor...
It seems like a problem of lack of midbass.. but it could actually even be a problem with the low freq range..

actually the lows are good...im happy with that..but anything mid or higher is lacking....the sub is a dvc 4ohm...wired in paralell for 2ohms.....the amp sports 4 15amp fuses....its a decent amp and has plenty of power for this sub.....and i think that 1.5 is the recommended volume for the ported enclosure....the amp is set almost at half gain and very low on the bass knob....the frequency is set around 40hz i believe..ive got so many adjustments on the deck though that it might cause a problem....i may just have to play with it until i get the sound just right.

Your LPF is set too low. Try adjusting it upward until the bass gets a bit too middy, then back of thil it sounds full and robust in bass and lower MB.
Also, amping you 4x6's would help bring up the Mid/Highs. If you do amp them, stay at rated RMS power and cross them at 150 - 200 Hz with your HPF. It's about the best you can get when using such small format speakers. A pair of 5.25's or 6.5's in front would really help the Mids.

ok so i fooled with the settings on the deck....and i got it to sound pretty good..( as good as could be expected) ...this deck has quite an extensive crossover and sound staging set up.
