SA8's ported by Subthump.com. Any interest? Crew Cab and Extended Cab Trucks

I put the enclosure calc, the mats for a perfectly tuned 2 x sa-8 under seat enclosure could be made for well under 30$ worth of 3/4" MDF and like 5$ worth of carpet etc...not worth 160$ at all but hey...to each his own..

Well not everyone has access to equipment. I use to build boxes when I was younger and lived with my parents. Now I live 300 miles away and dont have his shop. I have a house now, but before, I use to live in an apartment. Even if I had the tools to cut the box, am I suppose to cut the wood in my apartment bathroom? My point being, not everyone builds their own boxes. Alot of people dont have the skills, the access, the ideal location, etc... to make their own boxes and are forced to buy a prefabbed box. I haven't been able to build up my tool collection yet since I have a house. I am going to make more of an effort to do this once I get a house that has a garage. My house's garage was converted to a media room. I didn't like it, but I liked the house and the location. Now Im looking for a house that has an attached garage.

So this box, will fit perfectly underneath the back seat of my 2008 crew cab sierra? I didn't really understand the dimensions. Just a bunch of numbers without being described as side, depth, bottom, width, etc... Sorry for my stupidity. I know how to build boxes, but I would need a better translation and Im not sure how this box design was created if I didnt give any dimensions of my truck, unless someone has a NBS Silverado or Sierra Crew Cab or Extended Cab truck and took dimensions.

But Ill probably end up doing this little project over this summer, take my time on it and try to squeeze out as much of airspace as possible. Since I already have 2 12's in my truck, I can take my time on this one and do alot of experimenting. Plus my other half of my question in this thread is.... would it even be worth it to try this?

As in 2 RE SE 12's in a .83 cu ft (each) sealed box vs. 2 SA8's in a custom ported box. Is there a chance that the lesser cone area subs I currently have in an less than ideal small sealed enclosure out perform 2 SA8's in a ported box?

Horse crap. Where ever u buy wood at cuts it, just hand them a cut sheet. The cheapest tools plus a 2-3$ bottle of wood glue all work perfectly fine.

I bought a 20$ nail gun and it works perfect to hold till glue dries. I've built boxes on gerage floor, back of my truck. Simply put u buy a prefab box ur lazy. I had never built a box and did it and I'm a noob

not to mention ur gonna over pay for the box by $100 that's some decent tool $ right there

One again, not everyone has the tools necessary to build a box or the space to put it together say if they live in an apartment complex. And if they have built boxes before and they turned out disastrous, then they probably know that they aren't all that great at it and its much better and cheaper for them to buy one from a reputable place. So why say that and force a guy to go build a box that he knows he is going to screw up and bam. He made another box and its all messed up. So he needs to go to the store and get more wood and supplies for a second shot.

So my point is, is that not everyone can build boxes, or build boxes atleast to ya'lls standards. If this person finds a more convenient way of getting the box that he wants and doesn't have to spend a couple days building it, carpeting it, installing it, etc..., then I ask you... Why would this person be called "Lazy." They may just be working an awful lot. Like, by the time I get home work, its already dark. That would be a problem that would cause someone to build a prefabbed box. Some people don't have the skills or the money to mess up on their first box or mess up their first and second box, and having to go back and create another one. This way here, he can get it from a company that has done some testing on one (of many) box designs, tested them all, and figured that box design D works the best. Lets put that in the production line.

I thought you voted YES in the poll. Sounds like you are against it.

 

[Cruzer 10+ year member]

I voted yes because it would probably sell and help their business. I live in apartment so I use the bed of my truck and $20 nail gun. So there is no bs about no space or proper tools IMO.

I my self would like to see a prefab ported box for a SA-8 for the double cab tundra. I am going to try and build a box for a 8 i have laying around modeled for the SA-8 this weekend. I unlike most can go into work and use their tools huge table saw can easily cut 4'x8' sheets, a half dozen jig saws, half dozen routers, hell even a cnc router.

...Well not ever...om? My point being, not...

I know what happened...You missed the actual RE Enclosure calculator I linked...and just thought I posted a totally useless random list of numbers...rofl..here it is dude.

K now ya gotta just enter these numbers...in the order I have them here...

It will draw you up a box...alright print/copy those sheet sizes at the bottom...Take that sheet to Home Depot / Lowe's / Lumber yard...anywhere..have em cut you your wood..

K now hop on craigslist and find yourself a crackhead thief...k...he will have some dope tools for like 10-50$ buy them...hammer+nails...dude I've welded inside my apartment don't give me that crap (however I was worried about fumes so i moved it to my 4'x6' patio.... )

K so you take those sheets and glue those mufuckers together what is this 2nd grade? you can't glue 2 things together? doesn't exactly take a 5,000 square foot fully decked out wood working workshop..

k man Hope it helped...just buy the wood...and take your time...lay down a canvas painting tarp anywhere in your crib nothing will seep through it..(even though there is nothing to seep..it's wood and a light bead of glue...) k dude, man up and build you a box...it won't be pretty without carpet on it..but it will get the job done son. Carpet it if you want..

"So this box, will fit perfectly underneath the back seat of my 2008 crew cab sierra?"

Make it fit? lol...

Adjust the measurements in the calc to fit under the seat while maintaining a .6cuft @ 32-33hz (.6 is for when the speaker is in the box, it's -.1 which makes the box a .5)

Oh ok, gotcha. I understand now.

I wish I was able to do that kind of work at my apartment complex's I have lived in. We have strict rules here for mid-upper class apartments. We cant do that sort of thing in our parking lots. Especially my last apartment before I got my house. Our parking lot was an underground parking garage. No plug ins and was very cramped. Only get one parking spot per apartment and even then, I had to get a tow rope and pull a car out of my spot with my truck once that was parked there for 2 days and I told them to move.

hmmm odd. I found every cut to be a perfect straight cut, no gaps, great job on carpeting, great job on sealing it up, no rough edges, perfect cut hole for the subs, and the fact that they built an extra bump on each side for extra mounting depth, was impressive. Out of all of the prefabbed boxes, they had the most mounting depth and the most airspace for a crew cab Sierra/Silverado. Maybe you got a new person or something, I dont know, but I have built quite a few boxes in my life and have seen quite a few prefabbed boxes and have always been against buying prefabbed, but I also had the luxury of having a full on shop to work in. I dont now. But for the money, I was very impressed.

Ok, first Id like to say thank you for taking the time into writing that up. I appreciate it.

Secondly, I think you could have gotton your point across without insulting my intelligence with the "2nd grade comment" and the whole condescending detailed write up. I admit, I missed the hyperlink for the RE Calculator. I know how to make a box bro. I know what it takes. I dont need simple instructions like, "gluing two pieces of wood together." So although I know the nature of the responses that come with this message board, I should have known not to ask for further clarification, so I guess, this was my fault. I guess I asked a stupid question, so I got a stupid answer. So would this fit in my truck. Your response was, "Make it work." Really? So without any measurements of my truck under my seats, you simply came up with a box design and said make it work. Thats how people end up with boxes that dont fit right or extends out too far or the seats simply dont fold down anymore. Im not sure what kind of vehicle you have, maybe you have a crew cab or extended cab truck, Im not sure, but Im not going to make assumptions, however, it takes alot more to make a box under the seats of a truck. Its angled and is oddly shaped. Heck, anyone can make a rectangular box with a port with that calculator. I know. I have made on for my first and only car, my Grand Am GT when I was 18. I used a calculator just like that. It was easy. However, I cant use that calculator to make a box for underneath the seats of my truck, because why? Its not a rectangular box. Makes me wonder why I even joined this message board in 2002.

This whole thread was meant to see if there was any interest, for the people who wanted an easy solution, doesnt have the skills to build a box, maybe a teenager without the required tools, etc... Not everyone is a "custom box builder." Everyone is on a different level when it comes to their stereo in their vehicle. Some people will just goto best buy and have them do it, some people will take the time and buy stuff online and install it themselves, then you have people who will research and research, read and ask questions, take measurements, build their own custom box, and go the whole mile. Some people like the convenience of being able to buy a budget friendly box without having to learn how to build a ported box. When I first started building boxes, there was a bit of a learning curve at 16 years old, and not having a "father figure" to teach me stuff. So I screwed up here and there, learned about port size, port width, but simply putting, not everyone builds their own custom box.

I started this thread for two questions. I was just shooting questions back and forth with the owner at subthump.com and the question came up if there would be any interest for them to start mass producing ported enclosures, starting off with the very space sacrificed crew cab NBS Sierra and Silverado's. We dont have much space under our back seats of these trucks and doing a ported enclosure is awfully tricky.

The other question was would it even be worth it for me to go from my 2 12" RE SE's in a cramped sealed enclosure to a dual ported SA8 enclosure.

So we got a bit off topic and ended up right where I was not trying to get this thread to and thats the robot response of "dude, just build your own box." This thread wasnt meant just for myself, but for other people who have a vehicle like mine and would like to experiment with something different, a ported enclosure in a crew cab truck. I havent seen a ported box under the rear seats of a crew cab truck, except for Probox's ported single 10" enclosure, but what I didnt like about that box, is that it comes loaded with their own Probox 10" woofer. Id rather be able to pick my own woofer and not only that, but have more cone surface area than a single 10" sub.

Now let the a-ss ripping begin again. I know Im going to get a bunch of condescending smart a-ss responses

sweet i would have done the same! lol. ya we get a total of 3 spots to park, and we have a nice size yard. only fear of doing stuff like this at an apartment is everyone sees oh he is building a box for some subs, lets steal! haha

Thats another reason why I never even installed an amplifier or did tuning of my amps in my parking lot of my apartments. If I were going to do that, Id go to a friends house to install a new amp or if I were to go tune my amp, Id go to a parking lot of a local deserted mini-mall.

I learned from my friends. I learned the hard way to get locking lugnuts on my 20" rims. They were STOCK rims. I walked out of my apartment complex to goto work in the morning, remote started the truck and everything. Walked my dog, walked back with him, noticed my truck was sitting awfully odd. Was angled up. Mind you, this is a fairly nice complex on the edge of North Dallas and West Plano, I just got the truck, stock rims, truck was parked in front of the office and my apartment was on the 2nd floor (see bedroom window in picture), right by my truck. They had all of my lug nuts off my truck. The jack fell on them and they got away with one wheel and tire. Cost for learning experience: New wheel: $750 from GM Stealership + new $150 tire + labor + $30 tire pressure monitoring sensor.Would have cost me about a grand to replace one rim and tire, but I had a friend who worked for a wheel company that fixes damaged stocked and aftermarket wheels. Alot of times, people would come in and buy new rims from them and leave their stock rims. I got lucky and got the rim, new tire, free TPS, mounted and balanced for free for about $400. But I acquired a new jack, which I still have. lol How humiliating.
