outer dimensions were 38 wide, 22 deep, and 15.5 high. Port is 36.5 x 1.65 x 21" to tune it to 33 hz. Subs face trunk, the port faces down, travels along the "back" of the box, and turns in. some 200 watt subs and a 500 watt 2 ohm amp and your in business i guess! haha

Some tweaking with the headunit and amp has resulted in even better results than what Ive had. Ive got these 6 woofers moving!! With certain songs, Im seeing almost an inch of flex in the roof, and my windsheild is flexing quite a bit as well!. HOLY SMOKES, I never thought I could accomplish that on a single RF 1000 amp. I guess its the air that it moves thats really giving me the feel of some SERIOUS BASS! We did this SUPER budget install this weekend, a Kenwood 8105D with 2 RF P1 15" subs. Super cheapo setup, but we decided to see how we could do on a box, we ended up with 5.2 cubes and 60 sq inches of port, and this SLAMS too!! I cant belive the air this thing moves. simply amazed at the bass it put out. and the customer was dancing in place with the biggest possible grin from ear to ear with what he spent. It was quite enjoyable to watch. (Like no joke, this jeep seriously flexes the roof a full inch, i know not hard on a cherokee - but we paid < 250 bucks!)

Must be me then. I believe I hear a difference when different cone sizes are present, I have no proof of this, and I'm sure your right. So I don't want to argue. But thanks for your input on the matter.

Double post

I cant port lower.. that's the largest enclosure I can fit in there, its playing the notes, they sound good, but an 8" driver just doesn't produce the lows the same as a 15... This setup is the loudest I've had to date, and I think its cause of the fantastic box build. I couldn't be happier with it. There's NOTHING wrong with the box or porting. M5, and Honda, no audiblr port noise at all, I don't want anymore port volume really I think I found a perfect size for these woofers. Just a question M5 BUT when did I fault the driver? I faulted the size of the driver, yes, but i think the only one to blame there is me for buying 8s.. your quote completely missed (and I wonder if you even kept reading) but I clearly stated it gets just as low, it just isn't the same.. But this leads me back again. I started by saying I love it, and mention little things that I found about it. And all everyone reads is the small negatives that have no bearing on my feelings (and everyone else's that's heard it THAT LOVES IT!). It's perfect, it sounds great, gets low, sounds great, and makes me breakfast. Couldn't be happier.

.. just a little.:elol:

Got the box done, ended up going with 56 sq in of port, 3.1 cubes net, tuned to 35 hz. LOVING IT TO DEATH!! I ran the 6 subs in a series parrell, and the multimeter is putting the load at 1.1-1.2 ohms for the 6. Running them all off 1 RF1000BD. Its different bass tho, it cant grab those LOW LOWs like a bigger woofer can, one song for instance is rick ross, aston martin music. That song made some smooth and loud lows with my SoloX, and got real deep and loud. With the 8s, its as loud, and low, but its just not the same. Now apply that to the other 99.92% of my music and it actually helps it out. It keeps the music cleaner, and able to be amped up a hair more without loosing the clean quality sound. I really love the sound, and the beats from one small amp too. Im hoping to hold alittle wow factor cramming 6 woofers in the trunk of a kia spectra

Have you had those 8's in any other boxes to compare? I ask because you said you've had other 8's that struggled. quite a few now, but I think Ive got them down Didnt love it the first time around, but since then Ive liked it much more ever since. I like the boxes with .5-.6 cubes per sub, with about 16 sq in per cube Holy smokes another one Ive got going (check the port area thread in like 10 mins) is up and running with 6 8's in a 3.1 cube box thats SLAMMING on 1000 watts. serious business being done with these 8's, and Im loving them to death. Just waiting for the next customer build to order some more(and probably grab more for me )

I'll tell him to stop by tonight, I got some of them from the install last night. They just look awful. Flash makes a car look filthy, and this is far from a show car.. barely a clean one.. so they don't look anything special

At this boxes ability to handle the lows. Very happy and the customer is super happy. Running on a rf 1000bd 2010 with bout half gain, quarter bass boost and at about 45 Hz tops. It could handle higher too, but it matches real nicely with his setup there. Pics and vids coming tomorrow

I'm on the mobile phone, so i will be brief.. much to my relief the box sounds spectacular! Absolutely crisp and clean, it doesn't get violent at all. Other boxes ive had 8s would struggle with certain songs, requiring me to turn down the gain a hair, where this box held strong. I'm amzed

from my experiences that Ive had so far with the 8's (and all the info Ive been absording on the issue), Ive found that i like the ports alittle bigger than that even. Ive made 3 different boxes for these sundowns, trying to acheive the right sound for my setup, and the cleaniest and "loudest sounding" bass came when i ran a pair in 1.1 cubes with 18 sq inches of port tuned to 36. I really wanted to tune lower even, but with the size of the boxes and the port required, I just couldnt get it any lower. The first box I made was 1.2 cubes with 16 sq in of port, and it sounded good. Infact i would have kept it if I had liked how it fit in my car.. but Im glad it didnt, cause after shrinking the box alittle and upping the port it changed quite a bit of the acoustics (but that also could be credited to tuning to 36 instead of 34) Because of that, Im hopeful that I will have good luck tuning my next box to 36, and using 56 sq inches of port for 6 of the subs, with just a hair over 3 cubes of net space. Theres alot of good info, but its mainly all mixed into the arguement. Really what I took from it all, is every driver / box / amp / electrical setup is going to require things to change in the port, and that is also based on your preferences. (i know, sounds basically like your back where you started, but with some basics from sundown, and here I just start building, and it I dont like it, I change it up!) I dont have anything to share on the 12s but once you start playing with some boxes, please keep us posted I have a build for some 12s in the works right now

Skip all other posts and read this one Im not trying to sound like a smart ass here, (IM REALLY NOT! I KNOW NOTHING COMPARED TO Y'ALL AND YOUR SUGGESTIONS AND COMMENTS ARE VERY HELPFUL TO ME) but of coarse its based on amp power and driver config, ive never argued that infact I dont think even ibanter or whomever has either. Hes saying box size needs to be part of the equation. And to a certain degree hes right, cause your box needs to be a certain size to maintain the specifics of the port, and driver that your looking to use. So im taking everything into consideration, and not just one post. Like Ive said in others, I dont come here for one peice of advise, I want to know what everyone thinks, what everyone recommends, and maybe even suggestions, those are nice. When its all said and done some of the specific comments might not have anything to back them up, but to some degree the principles they speak of should be noted. Im not defending or crossing anyone here, and Im grateful for info from everyone here Unless you just post a link to someones post saying this is the only one to read - cause its not how I choose to do my research. All the opinions here matter, thats how it helps me come to my conclusions, and without conflicting ideas the point of asking is gone. AND im changing the design to a single port between 50-55 inches of port area. Id like to go up to 60 but if I do it just throws off the space i need with the added length required.

Hehe thats good :-) ill do some vertical 2 in dowel and ihave added (edit typing error. On cell) .23, poles are actually 1 5/16.

Heres a design i put together, simple but im hopeful it will work out nicely extrenal dimensions are 37 wide, 18 deep, and 14.5 high. figuring basically .7 cubes in speaker displacement. Tuning to 34hz. running 2 ports, each port is 2.5" x 16.5", @ 25.5 inches each. leaving me 3 cubes net volume. Any potential problems I might see with this setup?
