subs in the trunk?

Why do subs sound so much louder in the trunk than firing into the cabin. Is it because the trunk acts as an enclosure or what?

i dont think they are louder.

subs in suvs are better imo

they do sound different tho.

Yes the trunk acts as a "enclosure" it has to do with the pressure created in the trunk?

I could be wrong. This is just my understanding.

Also, you may notice more output with windows down also.

Also, to add to the trunk thing. The reason they sound better facing the rear of the car instead of, say, firing throuigh the trunk hatch in the seat. Is because of the way the sound waves reflect and travel from the rear of the trunk.

im not expert but imo in sealed application the trunk acts as a bandpass of sorts you have your subs in a sealed enclosure in another enclosure ( the trunk ) that is ported into the cabin ... this could be totalt wrong but its how I justify it ... in my experience they ARE louder and cleaner in the trunk facing the rear ....

does this happen because of cancellation? if it were walled off, would it sound similar to the subs firing at the rear of the trunk?

before when i had my subs in the trunk, the whole **** rear end of my car felt like it was going to drop when the bass hit. And it hit harder, now with them sealed off they sound more balanced but i have to turn the gain to 75% for them to get decently loud. This shit sucks.

And something else i am very confused about is the fact that turning my gains to 55%, which is where they should be setting them with the DMM, they don't get loud. In fact, you can barely hear them, it's like my sister's car can hit harder and she has a sealed 10 off 300 rms. I am running 2 freakin type r's with over 1400 rms to them and i can barley hear them at 55/62 volume on my head unit with the gains set to 55%? WTF? There has got to be something i am missing here.

so this is with your seats down and its walled off firing into the cabin?

It's called proper gain setting.
