Are there any differences in the quality/loudness of sound a sub will produce in the cab of a truck compared to being in the trunk of a car?

Yes because of cabin gain.

so... what are the differences? lol

Closer to the sound stage = louder. No barrier wall to push through = louder.

i dont believe thats true because i kno at my headrest its not as near as loud as my windshield since im sitting right next to the sub and the sound waves are going forward, but when i lean up i can feel the pressure alot more, and i remember seeing someone building some shit from mdf to seal off their trunk from the cabin and said it gained them 3 db, and trunk installs ive always felt the bass more in my chest than in my truck and i kno my truck was louder than that particular setup. i was talking to grand masta from sound domain and he said that small trucks are hard to get loud in because there if very little cabin gain since the sub is so close

Not true, I have a single cab truck, and my ford explorer was alot louder with 2 12's than my single cab.

I believe the amount of air in the vehicle plays a good sized role as well. For example 1 12 maybe louded in a truck than 2 15s or something like that. //content.invisioncic.com/y282845/emoticons/uhoh.gif.c07307dd22ee7e63e22fc8e9c614d1fd.gif

Different vehicle, single cabin. WAY too many variables to really contest why one is louder than the other. I would expect the exploder to be louder anyway since there is more cabin room.

But thats what this guy is comparing...different vehicles Car and Truck. Hence why i said that

just like any vehicle, the install can make or break the whole thing. in a truck that is extremely important though. the install must be very well researched, planned, and well done all the way around. there are some very cool box designs for under rear seats and what not, that will blow away any pre-fabbed piece.

Ive been working on one for my single cab for the past few days pretty much non stop. Its hard as hell fitting 2 Rl-p's behind the seats.

Wow... that's one hell of a sentance.

Audio Dynamics is your answer. The closer you get to a corner, the more sound waves you can hear/feel that are bouncing off the walls. A good example is the whisper room found in most science centers like the one in Seattle. Stand on one side of the room and whisper as quiet as you can and the person on the other side of the room can hear you plain as day (20-35 feet between). Now the difference between the truck and the other guys car is completely different installs, too many variables. However, still a smaller cabin would be a factor.

I agree on too many variables, but i dont think that the closer a sub is to you the louder it will be. When i had my explorer i messed around with alot of different box locations, and IMO the closer i moved the box the weaker the substage seamed.

My bad... This is what I originally read:

Are there any differences in the quality/loudness of sound a sub will produce in the cab of a truck compared to being in the truck ...

glowin missed the "n" and smacked the "c" instead. More air space, easier to achieve SPL levels. Cars and trucks vary greaty between make/model/year. One car may have exellent acoustics one year but su ck the following. It's all in the install.
