anyone got suggestions on were i should tune the box to. i was thinking ill cut another tube to tune to 45hz.the class ill be in is limited to 53hz and below the port i have in it now is tuned to 28hz so not good for going for spl

got the 3rd sub amp in and have the subs firing back into the cabin , am going to a compition this saturday so need to pick up another sono tube to cut down for a higher tuned port , lil scared i might loose the windshield , video below is very low power

ty hoping to put a few more amps in today along with the lithium bank

low power testing with the subs in the mockup/test box subs back/ side fire 10 inch port tuned at 32hz

flipped the box around and i think i like it better with the subs facing back , cant turn it up at home so ill have to see what it sound slike on the driver to work and ill pull out my rta again and see if it changes anything , keeping the power down while i do testing in this osb box , next day off from work ill prolly build the good box for theese so i can put some power to them , its warm enough now i can get my lithium installed as well gonna need it with all the amps im using to drive theese things

rta testing is looking great i want to test a few more port lenghts and also subs facing back but looks liek this box is good and i can now build the actual box

test box getting there the one rweason i didnt use carbboard was cause i also planned on putting the subs in this box to see hwo they sounded so i could see if i needed to make adjustments kill 2 birds with one stone , if this passed the hearing test ill go ahead and build the identical box out of the ply edit dont have my areoport yet so a 10 inch sonotube is the standin for the test box tommorow i think ill have it in so i can see if i need to make any changes for the real box , the rest of my amps get here tommorow as well 6x 1500watt amps to drive theese 3 12's

so i had to shrink the box slightly from 6.3 net to 5.9cft net , still models very well though im either going to fire the subs into the cabin or to the back of the trunk port is out the side due to port lenght port works out to be 10inch x 24 , though i do need to recalculate port lenght now that volume has changed . this was always a long term project ive got so much to do still , tons of fiberglass work on the door panels full sound deadning , more wiring , more amps to install , i work alot so time is limited maybe by the end of summer ill have this wrapped up 100% this is the aboslute biggest box u can put in the back of a nissan sentra lol atleast that is removable and or lets u still acess the spare tire , as i know i can get an 8 cft net box in there

bought a hseet of osb along witht he ply to build the box , got the osb so i could mock up the box i speced to make sure it fit and didnt need to be changed without having to cut up the expensive wood first i have to slightly adjust the height and depth to be able to get the box in and out of the trunk but yup i should have those 3x 12's in the car soon

delivery day

as much as i really wanted to swap to 4 12's its not possible , the box i came up with pysically fits but it has to be built in the trunk , im not going threw all that , so i ended up ordering 3 12's to go in the car and designed a 6.3net cf box that i can get in and out of the trunk of the car the only thing i may change is the port but for now i think im going to stick with the single 10 inch areo port . the 6.3 will be true even after bracing as i just calculated in extra sub displament to make up for the bracing

started to mock up version 2

besides needing some ring terminals to put on the push terminals shes done

amps lithium banks and mids in highs theres a whole back section to that amp rack thats going to go with the bottom section thats im going to do a bunch of stuff with its going to cover the factory trunk to cabin opening im going to build a octagon or oval opening into it and the mids in highs will go down the sides its hard to explain will make more sense once i get to that part and start building it , its just starting to get warm enough here now i can start doing all the sound deadner and fiberglass work , i also ordered 4x bad ass 12's that will eventually make there way into this build , i finially figured out how to get a 8.2 cf net box into the trunk of this thing parts came for my monster 8 test build still cant decide which cone i want to use the tall roll or the mega roll cone

got a lil more work done , im leaving for vegas tommorow so hopefully today i can get the amps turned around and start mounting them all

started roughing in the top for the amp rack , need to goto my friends place ot use his table saw to cut the lexan windows

i like the project part of the build and the journey of getting there , i ve already designed a 9cft box for four 12's that fits in this car but that will be a long way off

was goign to go with the sa's but i think ima build something with a bigger motor , sundown on the left 183oz tipple stack project on the right

started mocking up my amp rack , this rack has 3 layers what u see is the middle layer , the bottom layer will have all the power/ground wires distro , basically all the wiring , the wiring will come up threw the layer u see directly into the amps. and then the middle layer is getting 4 inch high sides all around so i can put a lid on it , the lid is going to have a 18 x 48 " piece of 1/4 lexan in it so u can see all the amps , all in total there will be 6 amps across that rack 4x 1500w monos and 2x 4 chan amps , i jhad to wrap it up for the day so i just wired all that stuff up so i could still have my music when going back and forth to work for the time being prolly be another 2 weeks before i have enough time off to work on it again

tore out the seats n stuff from the back of the car today and got the box painted and reinstalled think im going to put the subs facing the back of the trunk again because my slot port is on the face of the box and now its kind of firing directly into the rear wall there . as far as the amps i was thinking originally i was going to do the 4x 1200.1's across the bottom and the 2x 600.4's on a dual angled floating amp rack in the opening to the trunk. but now im thinking about putting the one 600.4 in the middle of the 1200.1's which would look cool when i put the lid on the amp rack with the lexan windows over each amp , and then finally put the last 600.4 in the trunk opening on an angled floating rack

so i wasnt planning on this but i just bought 2 sa-8 motors/baskets , and now im on the hunt for 2 more , going to swap the e's for sa's

not to bad for cheap speakers for the door panels for now ( friend gave it all to me ) but the 6.5's are being replaced with recoil audio stuff , keeping the dayton audio 8's , but hell dont sound to bad for sending full range signals threw all of it , just need to add some tweeters and then i can start the fiber glass work . all 4 doors will have this same setup
