Box design 3.69 cubes net. 4.5x12.5x32 port tuned to 33.

ill take two... jk

we traded a motor for our welder. my dad likes to trade... got like a 6000 dollar digital mig welder for 800 bucks worth of engine parts and some labor. cant beat that. and our plasma cutter isnt that great i think it only does like 1/8 thick, maybe 1/4 if its clean metal... and hey whatever works, i have a lot of harbor freight tools. cool thing is they usually go bad before there thirty day return policy so its no problem getting it replaced... haha

with any one of these amps the IA's will pound. build the box right and you might be running your friends out of your ride in hatch with that much power. dont wanna get your hopes up but you should def be out doing the L7s unless he has gobs and gobs of power. but those IA subs you got, they are awesome subs and wouldnt give em up for just anything... lol. i havent heard them personally, just from the reviews ive read and the L7s i have heard i can only imagine. good luck with the search and box!

thanks! yeah they definitely make life easy... haha! im lucky my dad has all this shit obviously. pretty much anyone can do work like this with the right tools.

yeah i was thinking about bedliner also. i might even bedliner THEN paint over the bedliner... well see. either way the bitch is gonna get heavy coats of "stuff" so it dont leak or soak up water. thanks man. my dad and i have a machine shop. i used to work on helicopters, got experience doing a lot of different mechanical things at a young age. have done vacuuming composits (sucking the air bubble out of fiberglass work basically) lots of metal riveting and "like" metals studying, metal tolerances. Have done a lot of engine machining, used to build engines with my dad. (my dads occupation) have built a few hotrods and worked on my 71 nova and have been helping with my dads 8 second 68 camaro since i was a toddler. needless to say i have a pretty fair mechanical background...

im doing a blow through... and the subs werent hitting the seat. and yes it was the box that made them sound shitty, same place i bought the subs from designed the box.

Okay, so ive been trying to decide what i want to do with my 600 dollar tax return. i get it in a week. =) not bad for only working two months eh? lol anyways... I have a 96 tacoma regular cab pickup with the bench seat in it. I have had a few systems in it. I have a brutus bxi2008d. My PLAN is to get an SA 12 and build a box as big as can behind my seat. (after many measurements and few boxes that ive already built i think i can get about 2.3 cube inside of a 3/4 box before any displacements) with that said onto my questions... i have been using the12volts calculator for port length.... with from i have heard the general rule of thumb is 12-16 inches of port area per cube correct? if i were to be using a box roughly 1.75-1.9 (after displacements) that would call for 21-30" of port. and a six inch round port is 28in^2 right? so according to to 12vols calc a 6" round port in a 1.75 cube box needs to be 35.6" long!?!?! (tuned to 33) And the airspace a 6"x35.6" port would roughly take up is like over have a cube!!!! if i can even possibly get 2.3 cubes that would leave me with 1.8 cubes before the sub. after that im like 1.6 something... long story short, am i dreaming trying to get this SA in my truck? lol i dont want it to sound peaky as hell, i listen to all kinds of music... or any other subs in this price range that like smaller enclosures? ive heard dc's do, but im not sure on there prices for the lvl 3? less than 250? (want to be able to get another batt, bunch of 1/0, volt meter, connection accessories, and maybe a cheap two ch with this money also) like im open to suggestions. got one twelve sealed now, have had two twelves sealed. but i wanna go ported now. might do two 8's? im worried about them moving air lowww though... seen them hit high numbers but all at high tones... so idk... sorry if i left any details out...

If you're using .75" mdf, how are able to be 3" away? from the end of the corner. obviously not 3" into the box...

This box sounded horrible. had two 3" ports on each end. did not sound good at all. it was like a total of 2 cubes, i didnt build it or do the design/tuning. i was very unhappy and returned the subs... i dont want that to happen again. im getting very frustrated, im thinking i just need to go back to two 12s sealed. maybe 4 tens sealed? idk... i cant make up my mind, i thought this two 8s box was golden.... help me pleeeaaase. this money is burning a hole in my pocket and i need more BASS!!!

ive tried two tens before... i really dont think there is enough air space. the biggest box i can make is 47x26x9x1.5 thats a 2.4 cu ft gross box. after JUST SUB discplacement the box is to its net size. where am i supposed to put a port after that? hence me moving down to the 8s. and the total width of that box and port up above i posted is 47 inches, the ACTUAL box itself is only like 36 inches wide. thought about making the box the full size and putting the entire port inside the box but i was kinda wanting some area to the side of the box to mount my amp and battery. and yes id love to have the cone area also, but like i said i kinda want the wow factor of the 8's. i appreciate your guys' input, im open to trying to fit two tens in there if you can help me figure it out, I'd much rather be louder than just cool. if you get what im saying.... this is the biggest box i can make. my trans hump and a cross brace are already taken out...

soooo after many box designs and fighting my 48x26x9x1.5 space ive come up with this. ive been on google sketchup/the12volt calcs for like 8 hours trying to get a box to fit... anyways what i came up was a 1.6 cu ft GROSS box. with a 2x9x30" port, 18 inches of port area. the port will be half in the box and half out (just what worked best after many designs) with the math i didn the portion in the box will be .2 cu ft, and each sub being .10 (correct me if im wrong) bringing the total disc to ~.4 cuft leaving the net volume enclosure being 1.2 cu ft. or .60 per sub. if this is sounding kosher im ordering the subs.

im interested in how it sounds. what are the port dimensions if you dont mind me asking? im thinking of doing a very similar setup.

kinda figured that was coming, ill be really careful, im running 1000 to a memphis pr 12 right now havent had problems, i just dont wang on it all day. pretty much dont listen to my music loud normally, just when i show a friend or something i wanna be able to lean on em for a few seconds, and be like "yeah thats only two 8s." i know they wont be covered. i know they arent magical super subs, just wanna make sure im getting the full potential out of em. i appreciate the looking out, not saying you guys are wrong either... just kinda looking for some help on the port design and tuning, never built a ported box...

after losing more sleep i decided to just run two sa 8's in a 1.25 cu box with a 2x8x32 slot port tuned to 31. gonna run 1k to each. hopefully jake still has some. i cant wait for the v.2 lol. just dont think i can get the airspace needed for the box and port for a twelve, or two tens, so ill just go with the safe route and do the 8 tuned low. hopefully they can perform like i want them to. might have to build a few boxes i guess... sound like im on the right track for the 8s with my port design and what not? too little port area? i listen to mainly rap. mac dre/andre nickatina/bay area rap. sometimes ill slide in a metallica cd though... as far as running the port across the top of the box, the box comes to a point at the top. im 6'2" my seat is one click from the farthest back, id like to have it all the way back but then i have NO room. but the top of the seat is pretty much resting against the back window right at the base. maybe a 1/2" between the two... i was thinking of an external port on the driver side, like coming out the bottom and then going up along the side of the box. if you get what im saying. but the port could only be like like 20" long, all the math ive been doing says this is just too small.

whoops old thread, my bad. im a newwwbbbb sorry. lol.

i just wedged some mdf between my cab and bed on my taco. by wedge i mean pounded that shit in there. the bed and cab still move but the cab doesnt smack against the bed anymore... if thats your problem... if its your box bouncing off your wall i would still do a sheet of mdf in between the cab and bed then some all thread through the box, through the cab wall, through the wedged mdf, then through the bed wall then tighten all of it together as one big piece. THAT would be solid. In my opinion.

Hey everyone... been into car stereos since i was about 17, am now 22, be 23 in april. worked at the circuit city roadshop when i was 18, learned how to do the basic installs and alarms. never got into custom stuff, but have done fairly large system installs in my day. I drive a 1996 Toyota Tacoma 2wd regular cab automatic, I have done everything myself, notched the frame, raised the gas tank, lowered, welded the roll pan, tailgate handle, antenna, hood squirters, put a 2004 front clip on(core support, everything), painted the truck myself also, it was my first time doing all of this. Ive had a handful of stereos in it back when i was younger, bought the truck with 2 mtx 8s, then put two infinty twelves powered by the same amp. shortly after i then bought 2 soundstream rfw 12s and a hifonics 1000d running at 1 ohm. it was the loudest system ive had. metered like 137.1 or something like that. so after that i wanted to go louder and got two RE SE 10 and had a ported box built i dont know what he tuned it to but it sounded like crap and hit only the low lows. metered @ 134 at like 31 hz or something ridiculous, i then sold the subs cut the top half of the box and put two alpine tens in there placed sealed. shortly after that i lost complete interest, got a girlfriend (whom im still dating) and sold everything i had. Well about a month ago, an old high school buddy called me up and asked me if i knew anyone that wanted his hifonics brutus bxi2008d. I got it from him. I then bought this memphis sub locally. the PR 12, put it in a .75 cube sealed truck box i had, NOOOO good. sounded like crap. so now i built a 1.3-1.5? cu ft sealed box and stuffed it full of poly fill, now i got this cheap POS movin, sounds decent too. anyways, long story short, i have the bug once again, and want to go ridiculously loud without cutting through. i have yet to see some real loud systems behind the seat of any regular cab pickups. please if you know of any, show me a link cuz i have LOOKED! i have seen some decent reg cabs with bucket seats and a sub setup in between but few behind. So my plan is to get another one of these hifonics 2000d's, 2 sundown SA-10s ported in a 2.25 cu ft box, 300 amp alt, and somewhere around 200-500a/h worth of batts. think im stupid to think i can hit 150 on the dash? maybe with 6k? i know you guys are gonna say the sa's wont handle 2kwrms each, but i will never be playing it loud driving around. only time ill put em to the test is on the meter. open to suggestions!!! been kicking around ideas for a while now. maybe two 12s sealed?

i could probably be talked into it. i was thinking about doing something with a tool box. but idk. im just worried about getting the thing sealed up, then keeping it sealed after a year of wangin on it ya know? all im worried about, i obviously dont care about cutting the thing up. i just want it to be reliable still. and to be honest i havent really seen a lot of clean looking blow through installs to get an idea of what it would involve. ive heard of people putting the whole box in the bed and just porting the sub into the cab, not actually cutting the entire back wall out just a section... i like this idea better for some reason... ill do some research on em, if you know of any links off hand that would be awesome. thanks for the input...

sorry i dont follow? if i put the tens sealed ill lose output? yeah, i kinda thought that, i was wanting to do two tens PORTED on like a 2.25 cu box. or in the same size box (thats about max amount of airspace im working with) putting two twelves SEALED, im in a ported vs cone area debate here. i want it to sound good but i want to be able to get ridiculously loud. i should be getting my taxes back in a week or two and want to order the subs/batts and another amp. like i said want to run two sundown SA-10s in 2.25 cu ft port box, using one 4" in port, tuned to 34. Probably just run my one bxi2008d on them @ 1 ohm so they would be getting roughly 1k each. ive heard they can handle this pretty well. like i said though im open to suggestions!!! if i was gonna go the two twelves sealed route i was gonna do the SKAR's. also have been looking at DC labs lvl 2 and 3 10s. ive been told pretty much all of DC's stuff like smaller enclosures, which is what im working with... Ive also been kicking around the idea of 3 SA-8s. but i want it to louder lower. i know its not the size of the sub that determines the frequency it peaks at, but even the makers of the SA 8 say it can only move SO much air...

THANK YOU ALL VERY VERY MUCH!!! Thanks for the comments on the stance, it doesnt look like much but i have done quite the work to get it low and still able to put shit in the bed... its lowered roughly 5/7 can go almost 9" in back with all the air out of the air shocks. not really car audio related, but just to give everyone a background on my abilities. Ive had the truck since i was seventeen. so it will be 6 years this year. Problems I fixed being so low (statically) Raised gas tank. made cross member taller (driveline started riding on the factory one) Had to notch the forward one also. Air shocks and notch coming through bed (would like to cover this some day) Front end swap Primer/Paint First time doing all of this. the notch was my first time welding, the paint and body was the first time Ive ever touched bondo. The truck isnt worth anything anymore but i dont care. its low and still practical. lol.

badass. how many cubes is that box? is that how deep the port is gonna be once installed? whats it tuned to? build is awesome though. i wanna wall my nova, lots o' people wouldnt like that much though... lol good work. keep us posted! thanks for sharing.

just stayed up for like 6 hours and read this entire thread. i have many things to say. but its like 3 am and i need to sleep. needless to say i couldnt wait till i got to the next page. your attention to detail is outstanding. and major props to your son for having the patience to get through the whole project without giving up. its a lot of work and gets very overwhelming at times. Ive done a few projects with my dad too, painted my pickup all by lonesome. just letting you know i understand (somewhat) how much work you guys have done to get to this point. something to be proud of in itself. once again. great job. i know Im late but i had to comment. Thanks for sharing, I appreciate it, im sure a lot of others do also.

found the SSA store when looking for some sundowns, noticed they had a forum, also heard it mentioned on other forums. im diggin it.
