SPL & SQ / Fabrication

Got a pair of MTX 8500 10"s that I am trying to sell (brand new in boxes still) but if they do not sell I am just going to use them. I am wondering what the best box style would be for a pair of these? I have pretty much unlimited space (Astro van) so that isn't an issue and they will be run on a XXX-6500D @ 2ohms so like 1500 each for burps, 700~ daily...

Subs: 2 dual 2 12" sa's Amp: kicker 2500.1 Car: 01 monte carlo Currently I have a 3.5cu box with a slot port, both fired towards the rear. They were fired into the cabin and I got a 140.x. I was told firing them the other way (how they are now) would post better numbers. I've yet to get metered though and can't tell a difference by ear. The plan is to build a new box with a 6" aero port firing to the right with subs facing back. Can anyone chime in with a better suggestion or confirm this would post good numbers? -Thanks

Ok. I've had 2 12" kicker l7's for a while, but blew one due to shitty setup, and not knowing anything and clipping all the time. Now that I've matured in car audio and have learned to respect the sq and not just bump myself stupid, I decided I wanted to go back and find out what the L7 is actually capable of given the right box. Now is where the trouble starts. I have no idea where to start building a box. I really have no idea how to either. Right now, the two subs are in a prefab dual ported chambered box and that is all I know. One sub is blown too, and I have no idea the tuning. I really want to build a new box. I'm not asking for step by step directions, just some …

Well I dont know were this falls into but my brother wants to change were his Soundstream BX-10 remote is I took a few pics of his dash and pretty much the interior so you guys can give us some ideas. It is a like an epicenter but not the original not an amp remote.I also want to know if you can take apart the box were the knob is and make it that"custom look"

OK I'm finally going to begin my build next week sometime. The box will be a center console going from the dash to the back seat with 4 12" RL-p's facing up. My question is should I have the port firing forward towards the dash? Or firing back under the rear seat? This setup is going in an '05 Chevy crew cab. Thx for any help.

Hey everyone. I've got a 99 dodge 1500 regular cab. I built a box to go behind the seats that was about 2.4 cubes and had a 3" aero port, loaded with a Fi Bl 12. I resently bought a DP 12 and it is quite a bit louder than my Fi, but I know it can get louder. I'm building a complete fiberglass box to replace this one, and it will have the same basic layout, but I'm putting in a bigger port. I've got a 4" and a 6" aero port. So my question is, which would be a better combo: DP with 4" aero port, or DP with 6" aero port? I can possibly fit either one, but I want to know which one would be better for me. My music style is rap just because of the bass, and I LOVE the lows, and…

Ok so im going to build a box for my new setup and im still not getting this port thing. Alright so the dimensions i want the box to be is. Height 20, Width 49, Length 50. And tuned to 32 hz.

im looking a good online site to buy some epoxy resin along with some 4 or 5 inch wide 18oz.(or so) cloth tape...anyone know of any good sites?

As many boxes as I built, my mind went blank today. I am trying to build a 30in long port with 1 bend. Do I measure in the center of the corner or along the inside port walls? Someone help a mind blank guy out?!

I have a 97 accord sedan, I running a alpine hu I have 3 JBl BP series amps. the 80.4 for my highs and Im running the BP 1200.1 per sub. As for Subs, I have the MKII 12's Brahma's (2) in a 1.75 cubic feet box I think tuned an 30hz. I don't think it hits hard enough I haven't had it tested yet. Im looking for some suggestions for a new setup to get a deeper and harder bang. Could someone help with some ideas, even if I have to use the whole trunk im fine with it

Can you order 1" MDF somewhere online? does home depot or lowes carry this? What about 1" birch plywood. I want strong but lightweight.

I need help mainly with the port calculations for a 10 cubic ft box and a 20cubic ft box This will not be a chambered Box I'm "not sure what size cubic ft box I'm gona build yet" So if you have a formula that can figure port sizes that will help allot this is for two BL 18'' subs. I can build a box just need some help with this. Thanks

I need help building a wall in my 95 lumina, i don't want to pay 1 grand for a wall that i could build myself. Does anyone near Kansas city missouri know how to build walls? and willing to help a fellow SSA member?

I have the Morel Dotech Ovation 6 two way set and was wondering if I could still use them to go three way sometime next year. I actually was thinking of using the Selenium 6 inch midwoofers as midrange or should I just get another midrange for this? I actually was told to use the Morel midrange but some say go with Hertz Audio midrange. What you folks think and I am going active with this in the future. Thank you.

I'm in the process of designing an enclosure for my Fi BTL UFO 12. I've drawn up two different designs with the only difference being the way the port is constructed. I've seen it done both ways, but I am unsure which would be most beneficial in my situation. Each design is 2.85ft^3 net tuned to 33hz for a front firing setup sealed from the trunk of a 99 Pontiac Grand Am. Does anyone have any experience/input on which would work best for me as far as loading, port noise etc.?Please use "left design" and "right design" when referencing for clarity as I am unsure what to call each one specifically. Note: I will not be adding any 45's within the port, but each edge will be…

hi, i planned to do a wall setup and the vehicle will be a 4-door Toyota Landcruiser. The wall will be as close as possible with the front seats but not up to compromising seating comfortably. How do you seal off the portion where there is window? i see that the front wall will be sitting halfway of the rear passenger door window. thanks

Hey guys! Im looking for someone who knows how to build sub enclosures for a decent price. Im located in Shreveport, Louisiana, so anyone around the area can reply. I want a ported box for 4 15 inch havoc subs. Please help!

Ok ppl I will be making a ported box for my subs, my external dimme. are 38" wide by 14" height and 17" in depth,, My question is, I will like to tune it to 35hz or a bit lower are these dimme ok ? my subs are HX2 12 "punch series dvc 4 ohms will this be ok ??? in order to be on the right step...... ok at this time I'm using bass box pro 6, I'm trying to get the hang out of it ok anybody correct me if I'm wrong ,vent side will be 12.5 height + 12.25 long and 2 inch from side wall (26.75 sq inch port) tuned to almost 35 ........

I've got these comps installed in my jeep with the tweets mounted on the doors @ the front corner of the window. As of now I'm running a reference 500 to them but plan on switching amps in the very near future. even with the crossovers @ -6db the tweets sound way too high and ear piercing. Does anyone have any experience with these comps? Any suggestions on making them sound a little better?

Enclosure for 12 FI BL Just wanted to see if anyone has any opinions on this box setup. 2.2 Cubic feet H x D x W 17" 13.092" 30" It would be 33 hz tuning. With port area of 30.8" . I am using 14 square inches per cubic foot Does this sound about right with my calculations or am I way off? I have the cut sheets written down but not sure if its needed in this post.

Ok, I tried to do some research about tuning and port area, so I didn't have to make a thread. I read a thread on smd and they were saying 10sqin per cube was better for low tuning and then others were saying other things like more the better so I don't know which is right. A lot of misleading information out there!! Much rather ask here and know I'm getting the right answer lol I'm most likely going to be ask pro-rabbit for a design once I am sure of my measurements,It'd be nice to know exactly what it should be, so I can expand my knowledge. I would like to know for my system specifically, but also in general. EQUIPMENT: Subs: 2 SSA Zcon 12s Amp: 2 Crescendo BC2000s(won…

There's a sanctioned USACI show about an hour and a half from here this weekend, thinking about entering in the "Consumer Q" class...anyone here have experiences with USACI SQ? I'm pretty sure the "Q" classes are just soundstage judging, no install, but I'm not sure. What are some things I should look out for so I don't get completely stomped? Thanks in advance.

Well i have this 8in sub laying around i was able to get a old school 160A2 rockford fostgate amp for $20 . I thought it would be best to build a box for it than to buy some cheap one so i could get all the bass i could from this little sub . So what i have in mind is building a ported box for best spl . This is going in the trunk of my mustang. But i cannot find any blue print for a small like 1.00cu or smaller enclosure . So if some one could give me some or just send them my way i would be very thankful.

What's the best way to figure out the displacement for each one of these? They will be about 15.75" long & 1.5" in diameter. I used them on the last build I did for the blazer, and they held strong, and were easy to use. So I'm thinking of using them again with my next one. Thx for the help.
