I just got a 15" Audioque hdc3 and I am going to get all new everything to run with that. Im guessing the box would be the next step. I have a 2003 ford explorer sport xlt and it has a relatively big area for a box. I am lost as to what size ported box to use and what frequency to have it be at. I'm looking for loud and and still being able to hit lows. What size box should I have made? All help is greatly appreciated.

What amp will you run it on? Around 4-5 cubic feet works great for those subs. Try tuning around 32hz if this is your first ported box

In the low 30"s as far as hz. If you want more spl tune higher. Get a ported box thats 4 cu ft.

Right now I just have an xterminator xr 2000.1d amp, but I am going to be getting all new everything for this and keep it. I have been switching my setup a lot lately and I am tired of doing it. I will buy an amp that will match up nice with the sub and box. So 32 is a good frequency to have it be tuned to? I'm going for really loud so is it basically the bigger the box the louder it'll be? A friend to me to get a 4 cubic ft box at 34 but I mean I want a many opinions as possible. I'm tired of wasting money and not have it work out.

The bigger box will usually dig deeper and play lower. You have to be careful you don't go to big or else the sub will basically act as if it does not have an enclosure. 4cu ft. net at 34hz is a good plan. A couple hertz difference is usually not noticeable to affect anything all that much. The lower you tune the lower it plays but is a bit less loud. Usually for music a range of 30hz-35hz is acceptable. 36-55hz is more for burping and SPL type setups (they wont sound THAT good on music but will get crazy loud). Hope this makes sense.

Cool thanks for your help. I just want to get the most out of this sub. Even though my next question is not in the correct section ill still ask. What type of amp should I get. I was told this sub can handle a lot more than it's rated to handle. And does the box size affect how much power I should put into it?

An AQ 1200.1 would be perfect and is not bad on price. The smaller the box is means that it can handle a few extra hundred watts mechanically (but you would still need to worry about thermal handling of the sub). A box on the larger side would be better if you aren't planning on running much power (it is more efficient). 4 cubic feet is what you want for this sub.

Did you buy one with copper or aluminum coils? Also what ohms are your voice coils?

Cool ill look into the 4cu boxes that are pre made. I was going to make one but If it has to be 100% perfect I'm not going to even risk it. It's a copper dual 2 ohm.

The bigger the box the deeper it goes but you will lose some spl. Go 4 cu ft at 32ish. **** a pre fab get custom.

Ok if you get a prefab make sure you know the tuning and port area before you buy it. Try to find 3/4" mdf or even 1" mdf anything thinner is junk. Most people wont recommend prefabs because they are tuned too high and do not have much bracing at all. There are a few members here who do custom boxes

Alright cool thanks for the heads up. I just talked to some dude earlier today from Craigslist that makes custom boxes. Ill talk to him tomorrow. 4 cu at 32hrz is what I'll tell him. Should I be specific as to what style of port? I'm sure he would have an idea since he makes them but I just want to be sure. Lol if I'm spending a lot of money I want everything to work together perfect and not have to switch stuff up. And I only need a aq 1200.1? The guy I bought this from is a professional installer and he said this will handle a lot more than it's rated.

Just get a slot port that's in the range of 12-16 sq. inches of port per cubic feet (in your case it's 4 cubic feet). The AQ 1200.1 does around 1,500watts RMS at 14.4 volts. They are underrated amps but you could always step it up to an AQ 2200.1 and just set the gains a little lower

I would place the sub firing up and slot port firing to the rear near the bottom in your SUV. Do you plan on ever adding more subs or will you just sell the stuff if you get tired of it?

If I were to get more subs I would probably have 2 15's and just get a new box made. I have had a bunch of different subs these past few months and I always just sell it and take a loss in the process. I'm tired of doing that and want something that I will be content with for a while.

The only reason I'm not recommending the AQ 3500 is that it will need several electrical upgrades like a high output alternator, bigger wire, fuses and more batteries. It can get very expensive. It is your decision though you could always wire it to 4ohms until you get more subs and batteries

Kschmitz91
07-28-2013, 02:32 AM
Yeah that makes sense. I'm sure I will upgrade all of that eventually anyways. Could that sub really handle the 3500w? It looks to be very durable and well built. And thanks so much for all of your help so far I really appreciate it!

Well if you wire your sub at 4ohms that amp would only produce around 1500 watts RMS. It would be around 4,000 watts at 1 ohm though. And no problem you are lucky to have an SUV I say go big if you can afford it or just save up little by little if you enjoy this hobby. Gotta go for tonight take care and good luck on your setup

What style of ported box would you recommend for 4 12"s in an suv? Meaning, where would you place ports and subs? I have 2 only I might get rid of, but then I might just add 2 more

Be sure to tell any "builder" how much port area you want. While this may not apply to some, it will apply to many local "builders" out there as they may have decent carpenter skills but lack in the design area. So going in with all the info you need upfront is always a good thing.

When I had 4 12's in my car it was a sealed box and it worked well. I just talked to the guy who I bought the hdc3 from and he told me to look into the Atrend 15Lsv box. It's 4.25cu ft tuned at 37. It's definitely cheaper than the quote I received from the guy to make one for me, has anyone ever had a Atrend box?

Ahmed Johnson
07-28-2013, 11:23 AM
Atrend's are ok. They are probably the best pre fab I have ever had. The wood is thin and the box is light but as far as a pre fab goes they're ok. A little extra bracing and cover the outside walls with extra wood and you could have an excellent box.

Kschmitz91

It's made of 3/4" mdf and the front is 1" thick. I found the Atrend 15lsv online shipped for 80. Ill probably just have one made but I thought I would ask since it's relatively cheap and it was recommended to me.

Subs firing up and slot port firing to the rear (horizontal near bottom). Or you could even do an octoport firing to the rear in the middle of the box with subs firing up also

Ok, so when you say rear, you mean pointing at the trunk? I have seen alot of people with their subs facing up.

Yea subs up and port firing toward the trunk latch (not sure which SUV you have). But when you open the trunk you will see the port in clear view

OP you really need to figure out how much power you plan to run. Off a 1200watt amp I'd go 4.5cubes net and wouldn't tune lower then 35Hz. Off a 2kw amp I'd do 4.25 net with the same tuning. 16^2 port per cube.

I've built a ton of daily boxes like that for AQ's and they work out very well.

I still haven't gotten around to actually making the box yet, but I have been looking into using an aero port for it. From what I have read it's easier to make and I like the fact that I can change the tuning of the box easier. I'm definitely going to be using a 2000w amp with it. Does anybody know if the hdc3 would work well with aeroport(s)?

mlstrass
08-02-2013, 02:23 AM
Aero makes no diff, any sub will work with them "assuming" port area/tuning is correct

That's what I thought, thank you.
