A few weeks ago I built a new box for my 12" Audioque HDC3 D1. Sub is wired down to .5 ohm. Box is 2.3ft^3 and tuned to 32hz. I also just ditched my wet-cell Ever-Start Maxx battery and picked up a Deka 9A31s for inside the cab. For a single sub setup, this thing does work. Ok enough talking, onto the pictures.

Box almost done:


Glued up, sub in, and glue drying:


Ditched the old box:


New box in:




The business end of things:


Got my Deka installed. Still need to make a mount for it. It's just sitting there for now:


Sexy ring terminals:


I'll try and get a video or two this weekend. Got all kinds of flex with this little thing. Let me know what you think.

 

Dang, that box is huge. Much bigger than it appears in the build pictures.

 

It's smaller than what it appears to be in pictures.

 

Forgot to add, the box will getting covered with charcoal carpet and I'll be making a box/cover for the battery.

 

Actually, not too shabby of a box, dick head haha

 

Haha thanks.

 

shoulda saved room and just upgraded the alt

 

$$$

 

1st time i have ever seen a battery inside the cab.

 

First time seeing a real system then :) haha

System is looking good man, where did you get those terminals?

 

^your joking im sure.

 

Battery in back… is that the thing to do ?

I would be afraid of the fumes if there were any.

 

extra batt is the first thing that u should do
this
its a sealed batt so no fumes

 

No, not at all..

 

It's quite common.

I had one from when I bought my 1/0 and I accidently bought the other two. I thought I was ordering a different style but I got those instead. Glad I kept them now. To answer your question though, Car Audio at CarAudio.com.

Like I said above, it's quite common. Plus as Josh said, it's a sealed battery so no fumes will be coming from it.

 

Yeah if you like to play your system with the truck off..
other wise your just adding stress to an already overworked alternator.
totally *** backwords way of upgrading the electrical system.
do not take this advice.

a "real system" would not run a second battery as a replacement for a HO alternator.

 

These vids are pretty goofy, but you'll get the point..

 

its very common to put a second battery in, its not the "*** backwards" way. that battery won't need to be charged as often as you think it will, that Amp won't draw that much.
As for the Op, Great install, looks like you can some noise with that.

Edit: a little background and adding more power :
If only a little extra current (12 to 19 amperes) is needed, the easiest way to enhance the system is to add an extra battery, or replace the existing battery with a larger one. If the difference is less than 5 amps, the existing power system will be able to handle it. For this, a capacitor is the best solution for every system, regardless of the presence of an adequate, but slow acting power supply.

 

hes running over well over 2000W of power last I knew. he needs a alt not a battery.

Okay expert, how many batteries do I need to gain these 12-19 amps of power and why wont my truck's 650cca battery let me have some of its amps? whats this extra battery doing that my current one won't?

 

Yea I plan on getting an alternator in the kinda near future.

 

more than likely he will need more than 1 battery if hes over 2k rms for sure.

a higher alt is a given tho.

 

As an alternator charges your battery, the overall Amperage of the battery is reduced by 2-5 amps. Depending on the size of your battery, you can have anywhere from 20 amp/hours to 30 amp/hours. (12v batteries have 36 amps)
in a small system, used by those who just want a clear sound, a draw can be anywhere from 4 to 6 volts, which equals 12-16 amps, since a normal alternator provides around 13 -14 V. two batteries should suffice.
as for the OP, sorry for taking the general classiness of your post down.

 

It's cool man. I'm just lettin yall duke it out haha

 

Here's a crappy video from earlier. Nothing was flexing because of the cold weather so the video isn't very exciting.

 

WTF are you talking about man. that makes no sense... at all.

You don't "draw" voltage, you draw current. and Ah have no significance unless qualified by the number of hours the battery is discharged due to manufacture variations.
you mean voltage drop??

i've read your post like 10 times trying to understand what you said, still no luck, anyone else understand it, maybe you could explain it to me.
