Regular Cab Truck, Not Enough Cab Volume for Great Bass?

I have a 2005 Ram Regular cab truck that I am having problems with getting the bass to sound right. In the past I have had tried one JL 10w3 on 500watts both ported and sealed, two JL 10w3 on 500watts both ported and sealed, one alpine type R 10 both ported and sealed, two Alpine type R 10 both ported and sealed on 500wats. Now i have moved to two Alpine Type R 8 ported on 500watts. Everything sounds the same, OK with windows up, Awesome with windows down, except for the 8's they always are lacking in bass. Starting to think the cab volume is the limiting factor. Going to go to two Alpine Type S 15s sealed on a PDX-M12.

Sound quality on system is great, just need more bass. Rest of the system is a Alpine INA-910, Alpine PXA-H800 DSP, Focal K2 Power 6.5 components in front, Alpine Type R 6.5 coax in rear, Alpine V9 5 channel running speakers and current Alpine Type R 8's.

Thanks guys.

I was afraid that the cabin gain is what I'm up against. I'm going to go forward with the two Type-S 15s and see if it helps, cause i have the stuff bought and its been a while since Ive got to build a sub box. Ill see what I get out of it. I'm game for just about anything short of a cab cut-out into the box.

Thanks guys, Just checking to see if I am the only one running into this. Not to many people around my area sink this kind of money into regular cab trucks. Going for different and impressive.

Thanks again.

Changed my setup this last weekend, couldn't be happier. Out with the old, in with the HUGE. took out the two Type-R 8" then built a new box, added another Alpine V9 and put in two Alpine Type-S 15"s. Plenty of bass. Nice and snappy in a sealed 1.3 cu.ft. each box, with room left for nice amp rack in the middle. I will try to get some pics up soon. Turned out much better than i thought and have showed it to a few friends that still believe the "bigger subs play low notes better but are too sloppy for rock music" stigma. I think i have changed their minds about big subs.

Thanks guys.

P.S. I know it should be more bass. two 15s is equal to about seven 8s for cone area.

Maybe i should clarify, the box is 1.3 cu.ft. for each sub. Total 2.6 cu.ft. This is what alpine suggested for sealed on a S-15. The Low end is lacking, especially with the windows up. But i listen to a lot of rock and for snappy 45-55hz bass the do great, windows up or down. If you roll the windows down and put on some rap, it does pretty goo, but i agree, it doesn't do 35hz real well. Overall, much better than 2 ported 8s.

Just thought i would share my experience with everyone, I know not all reg cab trucks have room for 2 15s, But a 2002-2008 Dodge Rams definitely do. Thanks guys
