My install's coming along nicely

Yup.

Won't be much but will make a lil noise.

What would be your advice? Abandon dual coil or a diff ohm level spkr?

Most Caraudio.com denziens as I call them are a lot better at personally insulting peolle than helping them.
That's why I posted my little door treatment post/log, just to help anyone possibly. I'd rather be part of the change I wish to see around here.

Hey im a newbie so I'll take advice from anyone. Ohms are new to me, as is the entire installation but you dont learn if you dont ask. I'll look stupid to learn.

I watched this video:



I got some good clues from this. Guy is obviously sponsored by Second Skin, who DOES make some great sound deadening stuff. And I LOVE those RivNut things, for making a machine threaded hole in sheet metal! I've got a bunch of 6-32 RivNuts and a cheap Chinese installer tool. Replaced all four mounting screws the rear 6x9s!!

You don't know how to try, remember?

Yes I do. I sit down with the RUX controller and the Alpine Owner's Manual and give it a try. DUH!|

LIAR!!

So if I got a P2D2 would it work at 4 ohm?

no u would need a r2d2 lol jk

a dvc 4 ohm can be wired at 8 or 2 ohm by itself. adding another sub u could do 4 ohm but ur amp can barely push 1 sub

just google "how to wire subwoofers" and theres a bunch of sites that will tell you how to do it

If i was you i would get a better amp, a mono sub amp.

I googled that amp you said you had and it cost 100 bucks. so u basically get what u pay for i guess

and my bad BoominTahoe i basically just said what u already said earlier except i had pictures lol

So after answering bjohnsons question I realized after looking at wiring diagrams that if i wanted to run 1 ohm on 2 dvc subs i would want to get 4 ohm subs not 2 ohm correct?

I just assumed that 2-2 ohm dvc could run 1 ohm but from what i seen it doesn't look like it. Can someone verify this for me? thx

lol For you, applying sound deadener is a science. To us, it's easy as cheese. It's not difficult dude.

John you wrote a couple pages ago that your system was done! But you haven't even turned it on? It's not ******* done! It will never be done because you'll always be trying to figure out why it sounds like crap.

He's afraid of our critizism from us. Which is gonna be true...since he doesn't take our ideas when HE ASKED us earlier in the thread to begin with. Us being the "amateurs" that we are, and we have experience in this field where he does not, I would think one would take ideas from us. But no. That was all he said thorughout the build log.....which isn't.

Yeah, it not very tough, None of car audio is very tough really. Playing with technology, that's all. And like computers, it's a basically all "just playing with other people code". Not difficult to do, but sometimes hard to do well for optimal positive results and as few negative results as possible. It's all basic optimizing.

And I LOVE how your LYING *** tries to make me feel bad/alienated with a "for you...but to US..." reference! ROFL!!! Like I'd ever want to be a member of your little club! NOPE! ;-)

Youre the one who is lying! You said you were finished this train wreck of an old install.

Yes...to get a total load of 1ohm from (2)dvc subwoofers they would need to 4ohm DVC speakers...each coil being 4ohms. All 4 coils in parallel.

A 4ohm dvc sub will give you: both sub coils parallel = 2ohm, both coils series = 8ohm.

The same holds true for the subs...(2) 4ohm subs can give you:

Sub 1 (in series coils) 8ohm in series with Sub 2 (in series coils) 8ohm = 16ohms

Sub 1 (in series coils) 8ohm in parallel with Sub 2 (in series coils) 8ohm = 4ohms

Sub 1 (parallel coils) 2ohm in series with Sub 2 (in series coils) 8ohm = 10ohms

Sub 1 (parallel coils) 2ohm in parallel with Sub 2 (in series coils) 8ohm = 1.6ohms

Sub 1 (parallel coils) 2ohm in series with Sub 2 (parallel coils) 2ohm = 4ohms

Sub 1 (parallel coils) 2ohm in parallel with Sub 2 (parallel coils) 2ohm = 1ohms

For 2ohm dvc subs just cut all the values in half.

The hardware install is finished. Configuring the DSP is not.

Here's the equation, so you won't need to learn it by heart but logically //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif : 1/R1 + 1/R2 = 1/Rt ( when wired in paralell) R1 + R2 = Rt ( when wired in series)

When only one DVC sub:

Rt : Total load

R1 : load of one coil

R2: load of the other coil

When more than one DVC sub:

Rt: total load

R1: load of one sub (total load of the two coils)

R2: load of the other sub (total load of the two coils)

With these two equations you can check the total load you will get no matter how many subs are wired together.

This thread is about as long as the T-Fade thread on CACO. T-Fade thread has some good info in it. I refuse to go back and see what this ruckus is about.
