The shop owner were I'm planing to get my box build asked me some questions and I dint know what to answer so decided to ask here

The questions were

1. What way do I want the speakers to face
2. For them to fire up, down, or to the rear (I sprayed some of "the right stuff" into my tailgate so its really solid trust me the border patrol thought I was loaded
3. Round or square ports
4. Sealed or ported

I have an expedition but I don't want to get rid of my third row . . .no use having an suv that only sits 4 right. This is the room that I want them to work with


By the way its for 2 w6's
AND I hear Spanish music will this make a difference??????? Thanks

 

If you have enough room without removing the third row, most people with SUV's go rear-facing, with square ports, ported.

 

It really depends on your circumstances. If you're going to be putting a bunch of stuff back there, you might want to consider down-firing or put a grill on the speakers if you rear-fire them. In SUVs, you usually get "better" sound with a rear-fire setup. As for ports, as long as your ports are flared on both ends or on all corners it really makes no difference if they are rectangular or circular. Rectangular (or slotted) just looks better and is easier to integrate into the box more solidly. Consider this as well! If you decide to go ported, it will be louder than a sealed box, but will require the box to be built bigger than if it was sealed. According to most people, sealed gives an overall better sound. Ported can sound good too, but it's response is pretty steep below the tuning of the port. Depending on how the box is built, you may get better lows with a sealed box than a ported one. It's a lot of science. Just ask yourself these questions:

1) Do you want loud bass or *clean* bass?

2) If you want loud bass that gets great low frequencies, can you spare extra verticle room to have the box made?

3) Is function more important than form?

Here is what I would do. Rear-fire the subwoofers and have grills installed for protection. Have one large slot port made that is up-firing (this will be the loudest configuration), this way if something falls back there you can reach your hand down the port and remove it. Ensure the box is tuned to the resonant frequency of the subwoofers so you can get optimal volume.

 

I honestly just want clean bass I'm not a bass junkie and I wouldn't want my bass to significantly overpower my mids an highs. So what would you guys recommend for *clean* bass and no I don't care what it looks like.

 

Sealed, rear firing. One 12" sub should be plenty.

 

Go with rear-fire, sealed, and dual chamber for both of your subs. You can always adjust the bass on your headunit if it's too loud for your mids and highs. 1 sub will be loud enough but 2 will play lower frequencies, and you can still keep them from being too loud.

 

How much volume do you have to work with back there? Dimensions would help too...

 

I would go with rear facing, seperate chambers with 2 12" woofers ported. I have a slot ported box. It is clean and loud . Gets low, no mud.

 

Good post. I would add that the port facing backwards is optimal in an suv for daily duty. The slot ports are unnoticable for noise in a big suv.

 

Generally, ports facing away from the sound stage will sound best, especially because the distance that some audible port noises have to travel will allow that noise to subside. In terms of volume, I've heard a difference in sound coming from an up-firing port versus a rear-firing port in my buddy's Navigator. Up-firing was *slightly* louder but sounded sloppier than the cleaner-sounding yet *slightly* quieter rear-firing port. But you are absolutely right, a rear-firing port does make for much better sound for daily driving and listening. Personally, when I'm running more than 1 woofer, I always go sealed. The only exception was my buddy's Vue, where he just wanted loud and didn't give two hoots about clarity. Large port, moderate box, two 12's, oh he got loud alright, and a noise pollution ticket.
