Thinking of getting this box for my 04 supercrew and I was wondering which subs you think would sound the best if I go with two 10's.I want some deep bass.This box has the most cubic ft. I've seen at .89.

Look for something that can use 1.0 cubic-feet of air or less.

I've heard and recommend JL audio subs, Infinity Kappa Perfect (I'm not sure if they still manufacturer these things, but they'll produce bass lower than you can hear).

You might also want to consider getting the single 10" box. It depends on if you want overpowering bass or if you want properly blended bass.

 

Thanks for the reply Corpsie.I'm looking for some good deep bass.Not like the factory 8" sub.I have considered making my own box too.Would I have to build a huge box to have it ported?I'm considering two jl w3v2 10's.or do you think they would sound good in a sealed box like above?

 

Remember, the factory sub has to be light weight and electrically efficient, so just about anything aftermarket (including 6x8 full range speakers) will sound a lot better.

JL Audio's site is unreachable right now, but from what I've read online the subs you have listed are dual-voice coils, right? Is there any particular reason you're going with dual voice coils?

A ported box? Ewwwwwwwwwww.

That site says you're going to need quite a big box if you want to port it. The people also recommend a sealed enclosure, so do I. Two 10's in a sealed enclosure will be capable of playing loud enough to do hearing damage.

Reading here, it seems like 0.85 cubic-feet is big enough for the speakers, so 0.89 will work.

My final conclusion is that the box displayed on the e-bay link will work well (especially if it's made of MDF and properly sealed). Deep bass always sounds best when the speaker is undercontrol and not flapping like crazy, so go with a sealed box.

 

Thanks again for the helpful info Corpsie.Piecing it together right now.I just order that box off of ebay and bought two jl 10 w3's.Which amp should I go with since both of my speakers are 4 ohm.I was thinking of the jl 500/1 amp.Any suggestions?

 

You could find a single channel amp that could handle a 2 ohm load and wire the speakers in parallel or find a 2 channel amp and wire the speakers individually.

I haven't looked at amps in a while, so I can't recommend any, but I can recommend that the power available to each speaker be between 100 W rms and 300 W rms. Anything more than 300 W rms per speaker would be an overkill, especially for 10" subs. I drove a 12" Infinity Kappa Perfect with a 300 W amp and it had plenty of power to spare.

 

The 500/1 is a nice amp. The design permits it to produce 500 watts RMS into any load from 1.5 to 4 ohms.

 

Check out the Audiobahn Pro Compression 10's I have only 1 and it has real deep low bass. Check out my PICS

 

Don't forget to take speaker volume displacement into account...

 

Ummm?

 

That means that you need to found out how much room (volume) those subs will take up in that box and subtract that amount from your box volume. If it's a ported box, you will have to figure out how much room that port will take up inside the box also and subtract that as well.
If both subs need 1 cb. and your box is 1 cb., once you subtract the displacement of the subs of lets say .15 then you end up with a internal box volume of only .85.
Which means if you want to have the volume the subs call for then your box will have to be 1.15 cb. not 1 cb.
With all that said, not having that extra .15 cb. of volume really will not make a big diff. in the subs proformance. It really comes down to the sub's ability itself as to how it will proform in anything less or more than what is rec. from the maker.
Sorry if this sounds elementary, but I hope it makes sense and if you were joking about you "Ummm?", then forget all of this.
:santa:

 

Do you really think manufacturers give us net box volume requirements? I highly doubt that.

 

Just about all rep. ones do. If it's not on their website, try calling them. If you can't get it, I would move on to another sub. No good buying a sub and not knowing what size box to put it in.

 

Indeed, I don't think I have seen any that DO NOT give net requirements.

 

But if the company knows the volume displaced by their sub, then it would make sense that they'd give a value of (air space required) + (volume displaced by the sub)
