Hey all, as most of you know I redid my audio setup recently. Now I'm running one Infinity 10" with dynamat in the trunk and rear deck. The bass sounds excellent from the front seats, but when you sit in the back or open the trunk to listen, it's very boomy and kinda sounds distorted almost. It tends to drown out the music.

The box size is pretty close to recommended and I think it's getting about 120w rms. Any ideas why this would happen, or is it just normal? Thanks.

Bass always seems to sound better the farther away you are, at least to me anyway. In the back seat your just too damn close to the sub.

Ok cool, so I'm not the only one. It sounds terrible if I stck my head in the trunk.

Bass develops as it travels further distances because of the low frequencies. The lower the frequency, the more distance you need for the bass to travel. 1 hertz = 1 cycle per second and its sinusoidal. That's why everyone points the subs away from the front of the car.

Thanks for the technical answer!

even more technical, at sea level,
(subsonic)
a 1 hz wave is 1130 feet long,
2 hz is 565 feet,
4 hz is 282.5 feet,
8 hz is 141.25,
16 hz is 70.625 feet long,
(human hearing spectrum)
20 hz is 56.5 feet long
30 hz is 37.6667 feet long
40 hz is 28.25 feet long
50 hz is 22.6 feet long
60 hz is 18.833 feet long
70 hz is 16.14 feet long
80 hz is 14.125 feet long
90 hz is 12.55 feet long
100 hz is 11.3 feet long
etc to all hell

tells you even the highest of bass notes are still over 10 feet long

more random notes,
1130 hz is 1 foot long
20000 hz (highest human hearing level, is still 2/3's of an inch long

maybe now you guys understand sound waves just a little bit more

Okay I think Ludlam really is God, because he knows everything!

Naw, he just looked that up

no i didnt... its simple really, the speed of sound is 1130 feet per second

wavelength = velocity/frequency

and i dont know everything, im just a science nerd

haha wave theory.. I hated that part of school but it all made perfect sense... So technically if you get pulled over for your low frequencies aka bumps, you could tell a cop it isn't REALLY loud.. it just seems loud due to the long distance of the wavelenth of whatever frequency was being played at the time lol
