Well im almost done my truck which is this summers daily driver........was supposed to be shown at performance world but wasnt out of the paint booth in time, anyways now its time to do the audio....everything is taken care of except what i wanna do for subs.....my truck has all kicker audio through out it so i wanna stay kicker......what do you think would be the loudest and sound best. I'v got 2000rms to work with btw.

2 15" kicker L5's
2 15" kicker L7's
3 12" kicker L5's
4 15" Kicker Cvr's

all set ups would be in a ported box, iv come up with a design so far for the 4 15's which would be a 18cft ported box tuned to 34hz....so im leaning towards the 4 15's which my amp would give them all the 500rms that they ask for.

imported_hdave

id say 4 15L5's

I'd say the 4 15's as well.

imported_BunEm

The 4 15" L5's would be bassalicious. Thing is, as a daily driver, it won't be music. Just....bass... O well it will still be loud as hell.

coreyhayman

**** i screwed up my own post.......lol, i meant 4 15" kicker cvr's not L5's.....lol

imported_hdave

its a hard choice between 2 l7's or 4 cvr's
id have to say 2 15L7's can get louder, those things in a proper ported box will be LOUD
but im bias towards them because i had one before


i know a guy from team kicker, i've sent him a pm and will let you know what he says

imported_hdave

i change my mind, 4 15" CVR's
thought u were gonna run 4cvr sealed or 2l7 ported

i see you have 18 cubed net which is plently of space for 4 cvr's ported
and 4 15's is way more pimp than 2 15's

coreyhayman

yeah i think the 2 15" L7'S would of been loud but the 4 15" cvr's should do the trick

imported_hdave

i pm'd you some useful info. good luck

coreyhayman

thx dude, yeah im def going with the 4 15's, just got my box design all worked out.

imported_hdave

edit:
looks liek you have approx 17 cubes net with 185 square inches of port area
that looks to be about right for those subs

when are you going to build it? i cant wait to see how loud it is lol

Use 1" mdf and use a centre brace. That much bass will vibrate the box make sure you brace it (very important)

imported_loudsubz

a good X cross brace in the centre should strenghten it up, as well as some smaller MDF trim pieces along the endes to strengthen the corners inside.

Where did you get the specs for the port?

coreyhayman

my buddy designed the box for me according to the specs and what he knows.......how much of a difference in sound etc would it make if i got all fancy and rounded all the corners off>?

imported_hdave

okay hey coreyhayman.
i just double checked all your specs.

i got this:
17 cubes NET @ 34Hz (i took the sub displacment into account, 0.141 cubic ft each, 0.564 total)
port: 37 x 5 x 14.25(length)
box: 38.5"wide, 56"deep, 18"tall
i did some rounding along the way. our boxes are very similar, so looks like everyhting is good to go.


also used some calculator off the net and it said port length should be 11.6" but thats quite a bit off from what you got and i got.

which program did you use for those box specs?

imported_hdave

sand all port edges and make them smooth, and like davis and loudsubz said, you will need a lot of bracing, i'd also use 1" mdf like davis said.

to tell you the truth, i always give a little extra port area to be safe, but from what i've heard, rounding port edges does actually make a difference.

imported_loudsubz

with a port that big, rounding the edges woulnd't really make much of a difference, because there wont be too much air velocity. With a small power with more air velocity rounded edges on both the ineer and outer flares is a good idea.

imported_hdave

hey do you think thats enough port area?
185 square inches for the 4 15" cvr's.

coreyhayman

ya so what do yas think of my box plans? will it work good or maybe tweak something a bit different? my friend is pretty convinced this is the best set up for me.
