i got 2 6x9's im about to put in my single cab truck. it doesnt have cutouts for 6x9's in it so im just making boxes. i'm going also put mounts on them so i can take them out of the cab and hook them on the bed whenever im hanging out at the beach... i want to get all of the bass out of the 6x9's thats why im going ported. any ideas for volume?:confused:

thanks

Depends on the 6x9's...I'm ported dedicated mids before, and it worked fine...I don't see anything wrong with porting your 6x9's for some added low-end(assuming you don't have a sub). Something like .5ft^3 tuned in the 40's will probably work well.

why stop? i just got this truck for 250 so i can save up money to buy a jeep cherokee. i know its not gonna flex any panels by far but right now im riding around with a f***ing boom box for a stereo. sorry i wanna have some sound.

what kind of speakers did you run? and no i dont have a sub nor intend on putting one in. its a single cab truck and while i could do a 10 or 2 im not going to put more into the stereo than i did to buy the truck lol. and these respond down to 28hz so i'm thinking tuning to 40's will be a good deal.

Why not just buy a pair of bookshelf home speakers, bolt them in your truck and call it a day? A set of smaller JBLs will only run you about 50 bucks on ebay.

because i want to gain experience with making ported boxes.... so im thinking why not start small...

I think this a kind of a cool Idea, I always wanted to try it, might be a new trend! LOL! I would think around what Ryan said would sound good, but maybe tuned a little higher like 50 since they don't like to go that low, at least the cheaper ones anyway.. It will help with port length too, cuz its gonna be kind of long with that small of an enclosure.

Yeah, 8sqin port, for .5 cubes is like 14" long! you could try a little less port area to bring it down a bit I guess since its not really a woofer..

just put a couple of 6" subs in there (http://www.woofersetc.com/index.cfm?currentpage=1&fuseaction=category.display&category_id=31&sort=brandName)

Could be, I guess since you put a 10 in that much box sometimes, it could be a bit big, maybe a .25 or .35 CF would be better? Gonna be an external port for sure then!

I ran Kicker SSMB8's in .75ft^3 boxes tuned to 45hz, and got some decent volume out of them. Xmech was the killer on those shallow mids though.

Yeah I can see that, no throw in those little guys!

this is what i figured from RE Audio's box calc

box width: 12
box height: 9
Box top depth: 5
box bottom depth: 8
Wood thickness: .5
square port height: 8
square port width: .4
square port length 1: 5.6
square port Length 2: 5.6
square port area: 3.2
box volume: .249 ft^3
tuned freq: 46.24



yes? no? maybe? other tweaks? lol thanks

The re calc works pretty good, I would say its definitely close..

I'd personally go with a bigger box and more port area. .25ft^3 is before speaker displacement, so you'll be around .2 after, and 8"x.4" is really skinny for a port.

i would say this is a noob question, but i think its just a general question really..

considering your average door isnt air tight or in a stock car its not even close... wouldnt almost any enclosure sound decent?

I did this in my convertible mustang when I was 16 and I loved it! I had like 20ft of wire for each speaker so I could move them around when we where at the beach or skate park or wherever. In all honesty, I really enjoyed it!

yeah its skinny but thats what was required for the tuning. and i'm trying to keep the box size decently small i might give it a lil boost in size but we'll see what happens. lol

and yeah it might be a noob question concerning in the box size etc but i didnt find too much on ported 6x9 enclosures. but id consider the box for 6x9's a general knowledge question lol. considering the only places for speakers stock in this thing are in kinda underneath the dash... and their only 4". while these aren't bad for mids... i need some kind of low. lol. the 4" are going in their respective spots and the 6x9's are going behind the seats. its a single cab truck so yea lol.

yeah i plan on enjoying it alot also. i got 40' of wire for my truck which is plenty for single cab. i think i'm only going to use 4-5 feet for the fronts each which will leave me with 15-16 feet for 6x9s. and my friends always have the problem of music at the beach... it would normally involve a couple open doors and an annoying *** "bing-bing" that makes you wanna fill your ears with sand!!
