box and ports

[thumper44]

I'm wanting to build a single chamber box for 3 10's and I'm having problems trying to figure out how to port it I've always built divided chamber boxes for multiple sub's I am limited on space on this build that is why I'm going single chamber a single port or 2 ports I just need to figure out the port size for this enclosure I'm wanting to tune it between 40 to 42hz the enclosure is 4 cubic feet

If you can post the max dimensions you have, the power you running, type of car and type of subs it will be easier to see how best we can help on manipulating the box for optimum performance. Most 10s don't require large ports. 1 big aero port should be enough or you could do a slot port to avoid running many small ports.

The maximum exterior measurements are 30"Lx18"Wx18"H and the car is a 1996 Honda civic hatch and I'm wanting the box to be even with the back of the seat the sub's are kicker compr 10's and the amp is a 1200x1

Your space is a little small for those subs. For optimum performance you need a box at around 5.5cubes net but you actually have under 5 cubes gross. Personally I think two of those subs in the right enclosure would do better than the three of them in a tight box.

I already have 2 now in a 3 cu.ft. box I'm not real happy so I bought 2 more so I can put 3 in my car and the single in my wife's car I'll eventually figure it out how to get it in there I always do

How are you not happy? Not loud enough? You see you are looking for a rather high tuning that may not work too well with some types of music.

[thumper44]

Yes just not enough a 10 sounds best between 40 to 45 hz if I have to I can build a sealed box but not my preference but I've got to give a little to gain a little

The comp 10s are 150W each so 3 of them can take 450W or so, despite the big box those 3 little guys won't take you far, if you really want to get louder you need better subs IMO.

Well I can say one thing I have used kicker sub and amps for 16 year I have had no complaints not one by the way the sub's are compR and they are 600w not just comp believe it or not the 2 that are in my car now are pushing 138 SPL on 400 watts not too bad for 2 10s in my opinion kicker kicks ass and all that other high priced shit can kiss kickers ass

What's with the attitude? So JoeX mistook which subs you have and said you might want to upgrade and you can't handle even that level of criticism?

There are many people here with a lot more car audio knowledge than you have that will be happy to help you as long as you are respectful and act like an adult. You might want to put more effort into doing that.
