Check out the SPL stuff...

These are DVC DD 3500 series woofers. Each woofer coil is 4 ohm impedance.

So final impedance from both is 1 ohms and DD M3 is running them at 1 ohms rated at 2400 at 12 V.

db Drags...not really sure about it.

We dont have but I would surely love to have one. We already have Termpro with us. Just the organizing part is left and one nice sponsor.

There are some modifications to the setup. The board on which the amp was mounted (behind) is the seat is not attached to the seat.
Earlier, after dropping the rear seat, the board stilll used to be up there by blocking the bass to comfortably enter the cabin. Now dropping the seat, the boot and the cabin are one.
Certainly the punch has increased. Sounds much more louder now.

Sunday we would be doing the BIG 3

Also, we have changes the rear JBL GTO 607C component speakers. They are replaced by Polk momo, Model number MMC690. They sound beautiful.
Its a 6 x 9 inch three way loudspeaker with external crossover.

The MMC 690 are 6x9 the 607 are 6" besides the MMC690 is about twice the cost of the 607 so it is an undertandable if they did better.

One for thing....the JBL GTO 607 components and JBL GTO 937 6x9 co-axs are for sale.

PM me if intrested for the speakers.

So what do you think how much output it is giving.

amit_sound · 19th January 2008, 11:57

Should be 150 dbs approx. But certainly above 145 db.

Though i have not measured them on SPL meter.

You are being very optimistic. Good

By nature I am a optimistic. Its good for health.

But, "hawa main teer nahi maar raha". My bro, was shown exactally the same setup by the installer in US, and two DD 12" on DD M3 hit 151.4 db on SPL meter in a SUV. isn't it a good score for 12" ?

So i am guess 145+ for a sedan.

nice... all the best with your ride. keep an eye out for parts falling out.

Neeresh · 21st January 2008, 11:16

what kind of battery power are you running?
I have 2x DD Z1A amplifiers, but for everyday use, I run a DD M3 because the current draw is very low compared to my other monsters, however it still does need alot of power.

I take it that you guys build street pounders and not SPL Cars since there is no SPL Format.

I know u said you coil imp is 1 ohm, but whats ur Box impedance?

amit_sound · 21st January 2008, 14:48

2 X DD Z1..... dude that enough to melt down a car

..

What sub are left at the 2 monsters mercy?

Sorry i did not understand about impedance of my box...How do i find that out?

Ya the street pounders are quite popular here. But soon you will be seeing a real SPL car maybe one from my side. Personally I have touched 152.7 db on the termlab and have tried to go higher also let us see what I can do on that. Currently using this sub the one on the extreme right.

The box impedance is the final impedance load on the amp. For reference on can get a plot it done in WINISD to see where are the peaks and dips to extract the max potential from the designed enclosure.

Since your from Africa what are your achievements in this field would love to see.

amit_sound · 21st January 2008, 16:06

Whats the cost of a complete SPL measuring kit?

Neeresh · 21st January 2008, 16:11

@ Low Bass Maker
That woofer looks off the chain!
I am captin of Team Speed and Sound, sound team (we have a drag racing team as well)
We have held a number of world records in the stock pro division. I was the loudest Bass Boxer last year (157.5). Thats done on one min avarge (not peak hold) with 1 door open. World record in that class is 158.
Oh, and you have to use normal music (no test tones or frequancies allowed).
Other then that my buddie Len is the oke hit the 185 that u guys are familiar with(was not a legal run because the sensor fell).
at IASCA finals did a 179.2 dBs in ultimate 2.
Other then that, I would say we have decent cars. None of our street cars (daily drivers) do anything less then a 155.
