i have an enclosure question..i plan on using 2 kicker L5's...whats the best inclosure to use for the loudest bass and to get the bass outside of the car...or what position to put it in...i want everything around me to shake

oh...and streeteffectz..if you reading this..how much more do you think it'll cost for a port or bandpass enclosure over the sealed box.

 

Below is an excerpt from an audio tips page at:

3.2 Enclosure type Advantages

Sealed Box:

Advantages. . .

Small enclosure volumes
Shallow (12 dB/Octave) roll off on low end
Excellent power handling at extremely low frequencies
Excellent transient response/ group delay characteristics
Easy to build and design
Forgiving of design and construction errors

Disadvantages. . .

Not particularly efficient
Marginal power handling in upper bass frequencies
Increased distortion in upper bass over ported design
When using high power and small box, magnet structure is not in an ideal cooling environment

Ported Box:

Advantages. . .

3-4 dB more efficient overall than sealed design
Handles upper bass frequencies better with less distortion
Magnet is in good cooling environment
When properly designed, a ported box will slaughter a sealed in terms of low frequency extension

Disadvantages. . .

Size (not so critical outside the mobile environment)
Woofer unloads below Fb
More difficult to design/ can result in boomy, nasty sounding bass if misaligned

Bandpass Box:

Advantages:

When properly designed and implemented, can provide superior LF extension and efficiency.
Cone motion is controlled more and therefore mechanical power handling is increased.
Cones are physically protected from contents of trunk flying around.
Output is easily channelled directly into the interior of sedans.

Disadvantages:

Difficult to build (not recommended for newbies), and very sensitive to misalignment due to calculation or construction errors.
Their characteristic filtering often masks any distortion that occurs as a result of amplifier clipping or over excursion and thus will give the user no warning that the driver is over-stressed and about to fail.
Need substantial mid-bass reinforcement to make up for narrow bandwidths in efficient alignments.
Transisient response is largely dependant upon the alignment chosen....wider bandwidths will result in sloppier performance, narrower bandwidths (and thus higher effiencies) result in better transient performance.
They can oft times be quite large.

 

u should go to the source, kicker.com and do a search on the recommended enclosures for kicker subs. u didnt specifiy which L5 so here is the recommended for their L5s in various vented boxes:

Model Compact Street Bass SPL / Deep Bass
S8L5 .66 cu.ft. + port, .8 cu.ft. + port; 1.0 cu.ft. + port;
1.5x9.5" port, 19.25" long 1.75x9.5" port, 19.75" long 2x9.5" port, 21.25" long
Power Handling = 300W Power Handling = 300W Power Handling = 300W
S10L5 1.25 cu.ft. + port; 1.75 cu.ft. + port 2.25 cu.ft. +port;
2.5x11.25" port, 19.75" long 2.75x11.25", port 17.75" long 3x11.25" port, 18" long
Power Handling = 425W Power Handling = 450W Power Handling = 450W
