I have noticed sealed boxes seem to carry louder out of the car than ported, I think because the cabin acts like the ported section of a 4th order. IDK

Very interesting... I'll have to do some testing when I get

My new car and subs

But wouldn't a ported box make the cabin act like the port of a 6th order ?

Yeah hatchbacks and tiny cars are extremely loud inside, my friend did a 152 or I believe a 151 at 29 hertz on 3,000 watts rms with a single skar 12 in a trunk wall , giant aeroport tuned low, Scion FR-S. Outside you could barely hear anything even with both windows down

151 at 29 Hz on a 12" (Skar) sub, on 3k ? I can' believe it ! In a trunk ?

That is incredible !

Did you want to write 131, or maybe 141 ?

Yeah sorry I got the information mixed up, 152 with 2 subs, 5k amp, giant aero, and burp score.

He did a 47 with the single sub, same box, same amp

The car was a 1976 Ford Granada. I still have it but the system is out of it because the quarters rusted through and the box started getting wet so I took it out. The first box was 4 cubes each. Took up the whole trunk and the subs were right at the trunk lid. That was ok but made a lot of rattles that I couldn't get rid of. So I built a new box 3 cubes each pointed forward at an angle like more than 45 degrees kind of down and forward. I made a tunnel for it to mate up to that went up behind the back seat. I cut the brackets off of the seat back so I could pull the bottom of it and lay it flat. You could see the subs through the tunnel if you tried. Kicker 6x9s and two kicker 8s in the rear deck. Polk separates in the front door. A punch 200 on the c15s. Rated 400wrms bridged at 4 ohms. A punch 100 on everything else. ploks and 6x9s parallel. 8s bridged tri mode. The punch 100 wasn't rated for all that but it never got hotter than the 200. It sounded good and balanced but a little bass heavy. I put a radio shack EQ in the trunk because it had a 35hz band that of course I pushed all the way up. Driving down the back roads one day I saw some guys standing at the end of their driveway. Years later I happened to meet one of them. He said that they heard the booming coming down the road and they were going to stop my car. Until I got close enough that they heard that I was booming to led zeplin. lol I had it set so anything would boom.

Higher sub frequencies will sound as if they are louder than they really are and carry farther, as the frequency lowers, so does the sound outside the car, but that does not mean it doesn't travel as far, it just means your not able to hear it. Larger subs will do the same thing allowing them to project the loudness farther out than smaller subs will, and in conjunction with a tuning of 40hz to 60hz they can be heard from really long distances, as i said before but eluded to the details, when you have a slightly larger than optimal box with higher tuning and larger subs and power you can get much louder outside of a vehicle regardless of brand.

I think the car at the gas station with the Xplods possibly sounded louder because many gas stations have roofs over the pumps and the bass may have been reflecting back down at you from the roof. The loudest vehicle I've ever heard oudside was a minitruck back in the late `80's in the downtown area of Westwood, CA... Nothing but giant glass high rises all around. We could hear it from blocks away. No idea what he had inside but I'm sure if we had been in an open field it wouldn't have been nearly as impressive.

Yeah you might be right, LOL my car is only loud under roofs or parking garages
