Explorer to F150, Wheres my bass?

[mr.michael 10+ year member]

I had this same system in my Explorer and now have put it into an F-150 ext. cab. But it does not sound nearly as loud. Did the larger cab in the Explorer make that big of a difference? My previous amp was a Planet Audio 2250d, but replaced it with this RF with enough headroom for a second sub down the road. Does anyone have any input?
System:

RE Audio HC 15"

Ported 6.5 CU. FT tuned @ 32hz

RF T20001BD gain controlled

All 0 Guage, with 200 Amp alt

Edit**

I went to my buddies house and put my box in his 93 Hatch Back Civic, and it pounded like crazy. But in my truck its so mellow. Do i need to have a different box made? Any ideas where to go from here to get my sub sounding good in an ext. cab truck?

hmm, well, ur box sounds better in smaller spaces so idk tune it either alor lower or higher ya dig

What orientation is the sub and port?
In alot of ext cab trucks, sub up, and port facing the driver side at the bottom of the box works great.

thats what i am
