3" diameter 17" long port area 7.07"squared. port area per ft 9.06

need help with my port right now my box is .75cu with 1.5" baffle and i have 1 3" flared pvc port 36hz on 700w and its just not getting loud enough
I want to switch to a 4" but was wondering if it would be too much port for the 8". its going to be in a 92 toyota pickup extd cab ill be tuning higher also
-
I had previsouly did the zuk mod (jeep xj coils in back to help with heavy loads) so i cut those out they gave me 5" lift the back . Brought it back to where it was with original saggy leafs and lowered the front 2". I like it so far you no longer have to hop up into it now you set down in it. The axle flip might be coming up next week
-
so you think ill need new shackles in the back? i was going to get off road 26mm t bars and then uncrank them so it will still feel like stock ride because of the higher spring rate. already have new shocks front and back, new sway bar. my axle's have 4.10's
-
ok thanks ill have my friends dad there to help he's done many s10 and mazda trucks. ill post some pics
-
is there any thing major i should know about before i take the leafs off or is it just strait forward take them off and put them under the axle
-
i was going to lift my yota but dont have the money and i like a nice lowered mini truck. before i get replies like "why would you drop a 4x4" i live in an area that gets a bunch of snow in winter so i need it.
now to the the lowering part. from what ive read 2wd yotas came factory with the leafs under the axle and 4x4's had the leafs over the axle could i just take the leafs off and put them back on under the axle?
For the front a tech at the toyota garage said that i could safley uncrank the t bars for 3in of drop so thats what im going to do.

i want to build a daily and spl box for a single sa8 v2. Already checked out spl gains thread learned lots of tips for gaining but not actual box construction
My problem is that i know nothing about building a spl box like what frequency to tune to, small or big, 45's and whare to place them? They are going in my ext cab toyota pickup for now it will be ran a 4ohm on 750w.
is there a middle ground between daily and spl?

ive been trying to find the name of this song for a while now you guys probly know it.

when i got the truck it only had 2 blown crusty old 4"s in the dash, new alpine HU, added 2 new pioneer 4" in the dash, the kickers are in the spot of old storage pockets so i cut some 1/4" ply wood to hold them and bolted them into the sides my amp is under the passenger seat and as you can tell the sub is where the flip up seats are. the only piece of wire you can see is the one going into the port.
-
all my speakers and subs in my room are vintage polk i have the 4 subs in my room running off vacume tube amps i built my self (each one has its own) amd the mids and highs are ran off one big 12 tube amp i also made.
-
it dosent even get warm and never smells i think they are better than kicker comps for the money and dont sound muddy. so far mine has held up to alot of abuse ive been running mine at 300w rms more than its rated for scince the day i got it and its totally fine
-
Thanks guys it was my first time building its an L shaped port. yeah my mids really started moving when i got one of those alpine plug and play amps its like 45w rms to the components. my HU is on -7 for the bass so it dosent go any lower.
the wind picked up after i started filming so thats why the paper was blowing around so much. Even though i would like to think a single 10 could move that much air
-
finnaly got aroung to building my own box for my single 10" polk dxi running on 700w
1.2cu ft, tuned to 32hz i rounded the port edges and all the corners inside the box so there are no 90* angles.
heres a vid playing some lil wayne. ill make a better one covering my whole system / install and when its not windy as hell and raining.
-
Ok thanks for the answers guys.
-
im going with a 15 havent decided wich one yet. wich way should i fire the sub twards the back of the seat or up and i should aim the port twards the passenger side right
-
i found a 12" alphasonik mayhem for sale in good condition for cheap would it be worth it? if not what would you guys recomend for a good 15.
the truck already has new deep cycle battery, volt meter, and big 3. would i need another battey
i have 4g wire.
the 600$ would be for the sub and amp nothing else
-
i know these small extended cab trucks can get pretty loud easily. im not shure of budget yet probly around 600$ would like to keep a single sub setup
-
well i have a 92 toyota extended cab pickup. it has new speakers in the front and added kicker 6.5's in the back i have 1 polk dxi 10" on 700w. im tryin to get as loud as i can. I was thinking going to a high end 12 or a 15 (any recomendations?) . im going to build my box at school for a shop project. im not going to use the back seat so any thing behind the front seats is bass space. im lookin for some pointers or tricks to get the most spl .
Thanks

I noticed most people are getting more output with these subs tuned in the high 30's low 40's range using 4" or bigger ports.
from what i've read on other threads a 4" dia would be more efficient than a 3" dia. That the 4" could move more air but would decrease the velocity of the air being moved
