Okay quick background, i have a brz 1700 and a pair of skar vvx 10s.
Well here's my problem, about a week into having my new system installed they just stopped working, I pull the subs out and see the wires burnt to a crisp; thinking it was a fluke i just rewired them and re-installed it (dumb, i know). It's been a few weeks since then and now have the same problem again, so I really need to figure out what I did wrong.
That is where they are burning, any tips on how I can fix this is greatly appreciated, thanks.

i like it, nice change of pace from just rap/hiphop
-
Call DC and ask if you dont believe me, Thats what I did
-
rob told me today theparts wont be in til at least the second week of july
-
From what Jeff told me, supposedly the parts are expected to arrive any day now
-
ive got some level 3s 250 shipped.
I need 10"
-
are the lvl 3 motors being pushed back as well?
-
see thats the debate i'm asking about. Is it a good upgrade or no?
-
10", dual 4 ohm. going in a mustang. not positive on amp yet because i'm not sure which subwoofer i'm going with yet box would be around 1-1.5 cubes after displacment
-
What's your opinion on that set up? I heard that the level 4 coils arent that good, am i better off sticking with a regular level 3?
-
I'll go with that then, thank you.
Another quick question, the kicker box it comes with has some fill stapled to the sides. Should I do something similar on this one or is it better to leave it as is?
-
bump,any help for the port area needed for aeroports?
-
and help on the two 4" aero port idea? Also, if I'm doing that, which has a 7inch opening, will the tuning be different than if I were tuning for a regular 4"?
-
I would not do a single 4" with a square 12" sub, unless the port has a good flare or you are not running much power.
As far as placement, I do ports on opposite sides and have never had a problem. There will be some who disagree.
If one side is sealed off from the other side (like tight fit in a trunk), it may have a screwed up frequency response, but no worse than running the port of a standard ported box through the rear deck. If it is just a box in a trunk that the sound can pass around, should be ok.
How about two 4" aero ports? for two square subs, 1200watts
-
But that is not correct. . .It does not depend on box size at all. Those are just approximations so people are not constantly asking how much port area they need, since the true mount of port area required for a port to operate correctly without compression is almost never achieved in a vehicle.
If I have a BTL 18 on 4000 watts tuned to 35 Hz in 6 cuft vs 10 cuft, I do not need a different size port.
If I have a BTL 18 on 2000 watts vs 4000 watts in the same 10 cuft, they do not require the same amount of port area.
Port size is correctly determined by cone displacement and tuning frequency. . .
So you think you can help me out with what I need?
-
So how many square inches of port do i need for aero?
-
fecupe i agree port area works with power and volume so what power u using to drive woofers
audioque1200d
-
So, for a box this size, do you guys recommend doing slotted ports rather than round?
-
Which would be volume, not area. . . we are looking at sq-in, not cu-in.
Oh, alright I understand. confusion on my part. So, if i'm going with that many ports, how do I get a frequency as low as 30?
-
That rule is mostly for slot ports, aeroport are more efficient, a round port needs about 9-13 SQ of port per cubic feet, said that, that´s why i would use minimun 3 4" ports, besides that, where do you get 56 SQ of port with a single 4" tube?????
pi x ®2
3.1416 x (2)2
3.1416 x 4 = 12.57 square inches!!
3 4" ports would be 37 square inches
Simple basic maths...
because the tube is 4.5" long as well.
-
This is starting to confuse me, because I thought that it was about square inches of the port for how much cubic feet I have. And based on that I need Roughly 64 square inches for 30hz in a 4c/f box. So, by having a 4" tube that is 4.5" long, I'm at about 56 square inches, which gives me 33.8 hz
and i'm at 1200 watts power rms btw
-
it's 2 12" subs and the box will be around 4 c/f total. Looking to tune it somewhere around 28-34, whatever is best

How big of a port is needed?

yeah I have all three wires spliced into one at the point it is circled. I thought about running a wire per sub but didn't end up doing it originally. Is that my safest bet, rather than making different connections like fused or something else? wiring isn't my strong suit
