I was designing a SPL box for 2 10's but i was seeing in other box's a triangle down in the port here is a image of my design.

is this correcto or do not is very efective in spl designs?

is for 2 10" it have 2.33ft3 with the woofer, port & 45's displacement, the triangle is not contemplated in the displacement.

i hope you can help me

the triangle is to help direct air flow out of the box so i would put it in there

I think thats a pretty common item placed into boxes SPL or not. The 45'd corners generally help with the air flow. Only thing to remember now is that you have a bit more wood in there when you calculate the total volume with displacement

im guessing its for a panda/marbella or similar? you should test with and without cuz it could help you or it could hurt you

i think it is, here in mexico the model is chevy this is an image

is the same as the opel i think so.

actually the box is all redy made, i put in 2 10" kicker cvr dvc 4ohms and a memphis mojo 2kw old school att 1 ohm , my wiring is 4 lines of 0 Gauge 2+ , 2-

i make 144.1db with the oem battery.

the subs do not support that power is to much in the 8 burp smelle like hot cake

i will put a pair of RE SX DVC of 2ohms to put the mojo at .5ohms and a hc2000 of kinetik or a nsb75 by northstar

i will test any way

thanks for the advice.

some more advice ?

I have seen good results in similar cars with the subs and port firing up.

A friend of mine has the same car (2 door version) but we didn't have time to play around with box positioning

nobody else?

what part of mexico you from, Im from monterrey, san nicolas, but i moved to texas....little sound systems in those cars bump

i'm neer im from saltillo dude, i wanna make 150 with 2kw i will make my best to try to make it. i see 150db with a same amp like mine in a 2 doors peugeot & 2 p2.0 of mmats.

hmmm gonna be harder than the 2 door ones but definitely not impossible

use duct tape!

If you have a meter available to you, do a ton of testing with position of things. I'm talking try it with the back seats down, visors down, glove box open, front seats forward/backward more, leaning towards the center of the car, etc. I've seen an extensive test like this done and it gained 2 db just from these little things. and yes, duct tape was actually one of the little tests! I think he applied it around the subs, sort of like an extra sealant between the subs and the box.

^^^^^ X2 on my van i gained by opening the glove box, pressing againts the window where the meter is, lifting the wippers(or however its written lol), pressing aginst the back door and making like a front to back on it..try anything that comes to ur mind

how many lines do you recomend me to put ? i have 2 for + and 2 dor -

the more the better...i would add til u stop gaining

how do you see the net volume off the box ? big, small, ok ?

any more advice
