I have a 2003 kia spectra sedan and I am going to build a box this weekend, I want it to be loud but still somewhat clean sounding, I would prefer to build one of the boxes out of the "free box plans" thread.

It's a 12'' Type R ( 1242D ) powered by an MDR-M500

It's in a 1 cu sealed box at the moment and it sounds clean but doesn't real loud. ( to be expected right? :D )

I'm thinking something between 2-2.5 cubes so it fits okay in my trunk.

Max height it can be is around 15 inches.


What do ya guys think would be a decent one to build?

Search!!

Like you said, 2-2.5 is good. Tune from 32-35, it all depends what you like/want out of it!

I had mine in 2.3 @32.

Out of the ones in the free box thing, this looks good:

But it's really not hard to just design your own that will fit better in your trunk...

That's the one I was eyeballin, it would actually fit pretty snug in the back of my trunk, too.

Wonder what it's going to sound like compared to my tiny little sealed box, haha... thanks for the advise though appreciate all of it.

2.0 @ 32Hz would be nice.

i wouldnt go any bigger than 1.7 cubes net... you will greatly reduce the power handling... but if your on stock electrical it might work out to your benifit to do 2cubes... but i wouldnt go any bigger than that..

Yeah I am on stock electrical, thanks for your guy's input, so the bigger the box the lower the power handling?

i'm running the same amp and sub. i got a 1.65 cu ft tuned at 42 hz.
will a 2 cu ft at 32 hz box make a difference? i play mostly hip hop and what i'm looking is for that bass that you feel in the chest.

It would hit the lows much better than your current box. I would do 2.5 tuned to 34 with 40" of port area. Never had an issue with power handling on my old Type R and I was giving it 1k rms.

sorry for hijacking your thread dewbie...

i'm looking to build on of those boxes posted on the free box design. there is a 2.5 @ 32, but is 2.5 a little too big?

I just had the same issue with the box. I went from a 1.5 net tuned to 30hz to a 2.3 net tuned to 32. I was way too boomy for the lows and I like hip hop. The rolloff went down pretty quick so If you like to listen a little lower volume sometimes, you might not like it.
Its almost like listening to tweets with a sub, no midbass. My 1.5 net was punchy and all music sounded good with it, not quite as low but still hit pretty good for lows.

Now, I bought the X, cuz this was why I designed my box bigger. In the box with the X, its about 2.15 net due to sub displacement and port displacement. It sounds alot better music wise and is a hell of alot lower than the R. Now Im happy.

is 2 cuft is the area for the sub alone? the port area is like another 2cuft. at least whats what im making right now. the box plan says 2cuft @33hz. its more like 4cuft tho..

ok, i'm dismissing the 3 cuft at 32hz from the carforum site.
from all the replies i think i'll go with a 2 cuft at 32.
i dont like boosting my music up, so the car next to me can listen to it.
what i like is that bass nobody knows where its coming from and you and whoever is in the car can feel it in the chest.

I'm going anywhere between 2-2.5 @ 32hz, whenever I get the time to build it.

if you take the measurements into the re enclosure calculator, it ends up giving you a 2cf tuned at 30 hz box.

i finished building my box. it came out pretty good. it's a 2 cuft tuned at 33hz. i get more low end bass than before, but the higher frequencies have softened quite a bit. i have to cranck the volume the get them going.
what should i do next?

You should probably crank all bass settings on the headunit and amp as well as the gain. Oh, and don't forget to add bass boost for extra dB'z :crazy::laugh:

A lot of low tuned boxes drop off with higher frequencies, its not uncommon. It is more of a function of the specific subwoofer and enclosure though. You can try to find a different sub that will work better or beef up your midbasses. Other option is not to tune so low, which obviously has its downfalls as well.
