need help and advice

You could always build the box in the trunk and form it to the car if you wanted to use your back seat. Or the other option is seal off your trunk and have the subs and port facing front. In that instance you would need to seal off the trunk completely. Im with John, go with the 12's and see if you can do a trunk wall and have it all unload into the cab.

you should do it yourself , it will be cheaper and a good learning experience.

an if you dont know how to do something hit us up on SMD!

Any trouble you run into someone here could help you .

it looks hard but really it is not as bad as it seems, hard work not hard to do.

Ive built boxes and installed plenty of set ups myself but ive never actually had to build a box inside the car the hardest setup i ever did was 4 12s in a blow thru on a single cab dodge pick up other then that its always just been building the boxes for 2 12s in a crown vic and i never had to do it inside the car lol but i really do want to go with a couple 15s in a ported box so if yall have any ideas on 2 15s that would sound right in there and beat hard let me knowive never used sound qubed so idk anything about how theu perform or what kinda space they need or anything

well you are in the right place, quite a few people around here are amazing at box design/engineering.

you could change the title of this topic to reflect the need for advice on a box build In your trunk.

Also you will need to post specifically what:

Amp

wire size type

batt(s)

subs

big 3?

max spec of the trunk.

what music you plan to play most

SPL, GP or SQ

I will say this I love my hdc3 12 (same motor,coil just different size) and just with te 1 on 1200w I can put a 140db score on the TL. Also it sounds amazing I have only ever had jl audio befor and to me this sub sounds as good if not better and half the price

[Joe Hagerty]

Alrite so wat do u think about 2 HDC312s? I had a few dif options i was lookn at

1: 2 15" type Rs hooked to a hifonics BRZ amp

2: 2 15" memphis M5s hooked to a memphis amp

3: 2 12" jvc arsenal subs hooked to a hifonics BRX or GLX amp

4: 2 15" lanzar optidrive subs hooked to a hifonics BRZ or GLX amp

Or the sound qubed option what would be my best bet to go with? I listen to mainly rap and r&b and i like bein heard from blocks away i can be heard from 2 block away now wit my setup i have but im lookn for 6 or 7 blocks away which would b my best bet on accomplishing that?

[jarrius]

I would go with the 2 12's personally. That would be about a 6cube box(just doubled my box because its made for 1 so I could be wrong)

And don't do it just to be heard from 7blocks away that is being a dick and gives us bass heads a bad name. I will tell you this now if that's your goal and want to annoy people you will not get much help. Be respectfull with your audio system and not be the dush that pisses people off because its funny

[Joe Hagerty]

Well only reason i want my stereo like that is cuz thats how it is out here bass is a big thing around here one of my dudes has 4 dd 18s in his burban nd it jus blows everybdys stereos out here away its a big thibg around here and not very many people get annoyed with it so its usually ok. How loud and acurate r tge hdc3 12s? How hard do tgey hit? Whats a good ammount of watts to put to em? And are the better then the american bass hd series subs? Ive heard alot of good reviews on the hd15s nd jl w7s but like i said im not real familar wit sound qubed im tryn to get as much input as i can before i put the money into em
