I have a extra cab silverado and want to go with 2 10" subwoofers. My question is what is the best subwoofer to go with, mostly interested in Sq but I want something that will pound also. The box I have is downfiring and the subs need to fit in this: mounting depth: 6.75" air space: .70ea. Thanks for the help!

1) Not all subs will work downfiring. You'll want to look for ones that are. Check this pdf out for information on how to determine this: https://www.adireaudio.com/Files/TechPapers/DriverOrientation.pdf
Check out the offerings at Adire Audio. Also try Image Dynamics. The IDQ series 10", which I own, was designed for small sealed boxes. It isn't the deepest subwoofer in the world, but the bass it does play is nice and tight.
Do you have an amplifier you're going to use, or?

I was thinking about buying a jl 500/1 amp to run the subs. Thanks for the link on if a sub can be mounted downfiring. Anyways. I was thinking about either the idq10v2 or the jl w3v2. Price really isnt a issue I have found the jl subs for $159. The RMs on the IDQ is 250 and the jl's RMS is 300. Does this mean the jl will play louder? Also which of those two do you think will have the better Sq? Thanks for all the help!

I would go with either one of those subs, the rms does not mean it will play louder it will just handel a little more power. If you have any local shops around your area I would go in and listen to as many subs as possible before making your selection, find a sub that sounds good to you. anyone can tell you what sub they like but it is best to find a sub that sounds good to your ears.

I could also go with the IDQ12v2? They dont recquire much airspace and their RMS is 350. Would they have as good as Sq as the 10's?

them image dynamics subs in my opinion put the jl's all the way up till the w6 to shame. If my competition didn't cary them i would be all over them.

So what size do you recommend 2 idq10v2's or 2 idq12v2's in a extra cab silverado downfiring? The 12's will have .90ft of airspace and the 10's would have .70 ? I want a subwoofer that has some bass but still have good sound quality. I listen to all type of music, which is best for me.

There will be very little SQ difference between a 10" and 12" driver. The 12" will play slightly deeper and is slighlty more efficient. If you have the space, go for the 12".
It takes double the amplifier power to make only a 3db increase in max SPL. 3db is not a large increase for daily driving and SQ listening. So, don't stress out about the amplifier power.
You are correct, the 12's would be good in around .90ft. The 10's would be good in .70ft. However, the great thing about these drivers is that you could push it even smaller without an audible effect on sound. You can push the volume down to .50ft^3 on the 10" and the resulting estimated response curve is less than 1db off the curve at .70ft^3. The 12" driver shows similar characteristics. You can bump it down to a .70ft^3 box without much loss.
In any event, the difference between 2 12" IDQs and 2 10" IDQs will be very small. If space is an issue go with the 10s. The 12's will play slightly lower and louder given the same amplifier power. They'll both be great for SQ.

So definitely the IDQ's over the jl w3v2? Also would their be a better amp then the 500/1 jl amp?
Posted By: kfr01
Date Posted: December 10, 2004 at 1:38 PM
The IDQs are much more comfortable in small boxes. To get the w3v2 into the same sized box you'll raise the Q above that of the IDQ. The transient response will suffer some because of the higher Q box design.
I don't think you can go wrong with that JL amp.

Would 2 IDQ12 v.2's with a jl 500/1 amp , sound better and hit harder then 1 Kicker comp vr with 200 watts to it? The kicker is sealed also but i has about 1.25ft of airspace where the idq's have .90 each which according to their site is a normal size enclosure for them. So which is it? Would the IDq's hit the lows as good or better tan the kicker also?

You can't even put Kicker and Image Dynamics in the same sentence (oops, i just did!)...::Begs the Audio Gods for forgiveness:: but anyways, the IDQ's will smoke them. Two other great SQL subs are the Adire Brahma 10'', and of course the 10W7. But for the budget, the IDQ's are awesome. No doubt about that. Really deep clean bass. Check out the IDMAX series too. I'm unaware if they make a 10", they probably do. Also check into Alumapro - great stuff. ------------- "I don't play games.

Will the 2 IDQ's beat the i comp Vr is SPL? Any other opinions?

Yes. The 2 IDQ's on a 500w amp would crush the single comp vr with 200w and a 1.25ft^3 box. 3 reasons:
1) The IDQ's are slightly more sensitive. Even 1 IDQ would give you more SPL than the kicker - even if you only gave both of them 200w.
2) By using 2 subs AND increasing the power by over 2x you'll be increasing the SPL by more than 6db over the single kicker.
3) The kicker in a 1.25ft^3 box is in a fairly high Q application. The low bass extension will be better with the IDQ's.
So, you're probably looking at ~+7db difference in SPL between the 2 IDQ drivers at 500w and the single kicker at 200w. 10db is a doubling of volume. Plus the IDQ's will have better low extension and sound quality than the kicker.
Anyway, they'll beat the comp in just about every way, given that situation. ------------- New Project: 2003 Pathfinder

Probably. Definitely in SQ !

theres plenty of better amps than a JL500.1 whats your price range for the amp?
Posted By: Vandals909
Date Posted: December 12, 2004 at 1:37 AM
I would like spend $300-400. The jl only puts out 500 watts and the RMS for two IDQ12v.2's is 750. What amps would you recommend?
Posted By: kfr01
Date Posted: December 12, 2004 at 9:24 AM
You're fine with 500w to the IDQ 12" speakers. You won't even gain 2db max SPL by upping the power 250 watts. 99.9% of the time you won't hear a difference.

i heard the idq's with 100 wrms and couldn't tell much of a diff from 300 wrms. We switched amps on the sound board to hear the diff, ,but there really wasn't no difference. On the computer it would probably show the bigger amp fed a cleaner signal, , but if you can hear that in a sub your abnormal. So 250rms to each sub should and would definately do you good. ------------- 2003 Chevy Avalanche,Eclipse CD7000,Morel Elate 5,Adire Extremis,Alpine PDX-4.150, 15" TC-3000, 2 Alpine PDX-1.1000, 470Amp HO Alt.

And frankly, not to beat this to death, but if you're frequently running at over 500w to 2 of those subs, it won't matter before long.... you'll be deaf.

So thats a thumbs up on the jl 500/1 , what about the jbl 600 watt amp? Is their really a sq difference between amps? Thanks for all the help!
Posted By: kfr01
Date Posted: December 12, 2004 at 11:37 AM
JBL is regarded as an excellent amp for the money. Please don't buy it just for the extra 100w though. You won't be able to hear a volume difference at all.

JBL = FANTASTIC!!! I'd take a JBL over a JL anyday of the week.

Should I get these subs in 2 or 4ohm?
Posted By: kfr01
Date Posted: December 12, 2004 at 11:24 PM
If you're going to get 2, get the 2-ohm version.
Then wire it like this:

The Jl 500/1 is stable at 1.5 , 2.0 and 4 ohm's right? So 2 2ohm IDQ12v.2 would not be working the amp to hard? Is $159 a good price for the IDQ's?
Posted By: kfr01
Date Posted: December 14, 2004 at 12:57 AM
$159 is a great price. They're regularly $200. Is that from cardomain.com?
You're right, 2-ohms is fine for that amplifier. As stevdart pointed out in another thread, that amp is very flexible, being stable and consistent across a range of speaker loads.
