SPL & SQ / Fabrication

im wanting to do a build using a mach 5 audio spl 12,sundown audio saz-3000d combo the question is ,will this be a good candidate for a mass loaded enclosure,or t box on the street. im very impressed with what peter w. kulicki has done with two soundsplinter rl-i 8s but i want to understand the enclosure more because id much rather build myself.

Hey all... got another question here . If you use aero ports, is it possible to build the box smaller in relation to a box with slot ports, or is the port displacement the same for both types? Thanks

a. Subwoofers in question, number of subwoofers & subwoofer size: Dual SA-10's b. Amplifier being used, specifically the model number: 1200 watt Hifonics Brutus (will probably end up upgrading it to a 2000) c. Fabrication skill level: will be made by a box builder d. Preferred material to be used (i.e. MDF, fibreglass, etc): mdf e. Vehicle which the subwoofers will be used in: 93 toyota celica f. Musical preferences: rap g. System goals: SPL all the way h. 37 Hz range

Ok question 1 : Im planning on building my own box but when they say have 12-16 sq in of port space what does that mean? Which part of the port do you measure to get that figure. 2 : would a T-line be a better choice for 2 BTL 12s with a 2.5cuft box? or a regular L-port?

I know some cars are louder facing back and some facing foward sealed from the trunk. i was wondering if anyone knew what was best for an 04 hyundai sonata? i was looking at a 15in or an 18in with between 3000-3500 watts depending on which amp i deicide on. looking for loud daily.reason for one sub is cost. thanks alot.

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?

What is the minimum number of yellowtops needed to run a Sundown 3000d? I've still got the stock alternator in the Frontier and want to see what I can do. BTW the Opti 50C is up for sale.

i'm planning on running 2 orion hcca 12's and the box i'm planning on housing them in aimed at 30hz. it's dimensions are 39" wide, 14.5" in height, and 32" in depth. my port measures 13" wide, 8" in height, and 27 3/4" in depth. will these measurements yeild my 30hz goal. i'm not that good with measuring volume and everything so a little assistance will be greatly appreciated.

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.

right now i have 2 18" in a hatchback with subs up port back will i do better numbers with subs and port up and i have 100sqin of port will i bennifit going to 150sqin of port any help please

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.

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.

I need help making a 2 4in port box enclosure tuned to about 33hz. can anyone help?

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

im doing a wall in my hatch back i will be doing bass race bass boxing and meca driveby but how will the best way to place the port drivers side? top?bottom? any help please oh and ill be using my 2 18"treo ssx subs

so I just took everything out of my trunk. which also includes the rug and spare tire. I'm not putting the tire back since I can't get it out when everything is in. so my question is should I put the rug back in? I thought I read somewhere rugs are bad for spl. thanks.

Getting ready to do a little sound deadening this weekend. This is going into an 07 Altima. Do I need to remove any factory deadener that is glued to the floorboard or any other place. I'm not talking about any jute carpet or material that can be easily removed with my hands. I know that some cars have factory carpet/rubber like padding on the floorboards, does this need to get removed or can I just deaden around it? Thanks. Thanks!!! :drink40:

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…

Today's massive frames and motors add challenges to designing enclosures these days. What is the general "rule of thumb" for the minimum acceptable distance from the back of the woofer's motor/pole piece vent hole and the back wall of the enclosure, or a port wall? I'm playing around with different designs for an older Rockford Fosgate T210D4. I can handle the designs myself, I just need some input in this area. Thanks in advance!

hi, i have been doing so searching and i see that some people use clay as a spacer and i am wondering 2 things. how well they work and the other being how do you do it. cuz i need 2" spacers on the cheap side and all i could think of on how to get the clay to work for me is use something like these http://www.homedepot.com/webapp/wcs/stores...03+501959+90025 to give the clearance and then just fill in the space with clay and more then likely us fiberglass resin to make sure it is seal.

seen it a couple of times during my visits to select products site. anyone try this stuff? i am trying to get a better idea of the result i would get with it. my car has this felty suede material in the center console and ashtray area. is it similar to that? i was thinking of using it to line the bottom of the amp rack and wanted to know if it is decent or i should just do real suede?

I have 15" height with 38" width in my trunk. If it could be made down to 36" width and just longer that would be great. I'm going to be housing two SA12s on a 1500d. Specs of the site say 1.75 each at 30 hz so 3.5 at 30 should be right then correct? If it helps I always listen to rap with a lot of low notes. I currently have a design from this site for a 3.2 cube that I will build tomorrow but if someone can help me out with a design tonight that would be great. 3/4 MDF. THANKS!
