If you kno, i have a lude and im lookin for more trunk space, if you've ever been in a lude, the trunk space is tight, and the Sub box i have now is HUGE!

heres what i have right now

2 crunch PZ12DBSQ in their ported enclosure

http://www.cardomain.com/item/CRUPZ12SQBP
and a Power accustic LT620/2 amp

http://www.cardomain.com/item/POWLT6202

im wonderin if its worth it to build an enclosure for these subs or just sell em and buy somethin better....

how is the Image Dynamics IDQ12 D2 v.2 (2 ohm) in terms of SQ and SL?

http://www.cardomain.com/item/IDSIDQ12D2V2
Or something else thats <200

Maybe for amp go one of these, what would you pick?
ID says 350 for RMS so im gettin around 300 RMS

Directed Audio DEI 750d

or you kno, you can recommend an amp.

I would go with the image dynamics all day, and any of the amps.I have onwed all three amps or installed all three and have never had problems. If I had to pick I would say the dei.

where can i buy the DEI... i mean i dont kno if i should trust that Full line audio.

and would one IDQ be good? because i donot want to buy 2 i just want ONE sub

another thing, should i put more than 300 watts to it, or i could just run the amp at one ohm?

class d's arent that clean but when it comes to bass. Distortion isn't all that crutial, class d's are real effiecent, not needing alot of power. I have hooked up the dei's 500 and 1000's to 4 12"s and it heated up but never cut out.

so you would suggest i get a class D amp :|?

How loud is the IDQ?

and will it be able to handle One ohm?
howabout the 600 watts @ 1 ohm from the DEI?

 
Rep Power: 0

Yep, I beleive they run @1ohm but check with manufactoror spec's before buying.

heres another q, what i would really like is the subs to feel like cannons when im listing to my rock music. you know what im saying? would this setup work? or should i go with two IDQ 10'', if i went with 2 tens, what amp should i get???

 
Rep Power: 310

Ex-03, I'm giving you the benefit here, but unless I'm missing something, it looks like you guys are talking about what impedence the sub can handle? Subs don't handle any impedence, they provide it. The amp doesn't produce ohms, EXORCIZT, the amp handles the ohms the subs provide. You cannot change a subs impedence, it is what it is. You can manipulate it to some extent depending upon the configuration, but that's about all the control you have. What you wan't to do is figure out what impedence that sub is, what configuration you'd want to run it at, parellel, series vcs, and then find an amp that will handle that particular load. Lets say your sub was 4ohm and had two voice coils. You've got a choice, parellel the voice coils and have a 2ohm load to deliver to the amp. OR Series the VCs and have an 8ohm load to deliver. The 2ohm load will give you tons more power, but your amp may not be stable at an impedence that low.

EX-03, I'm just assuming that you thought he had switched to talking about the DE instead of the ID subs?

BTW, the IDQ is a good choice for trunk space. That thing requires a small *** enclosure. Same with JL Audio 10W6 too. They require tiny little enclosures.

would the one 12 give me the cannon like effect?
or would i have to get two 10s?

 
Rep Power: 0

yep he did switch to the amp so without going into a five page explaination on ohms law, I just gave an example of what the amp will do.

and to answer my question? lol..

It sounds to me that you want a all around sound system a.k.a a soundQ+ system, that will play everything the way you like it all the time.You probably need an eq for that or a radio that has a built in eq. One 12 or two tens doesnt make much difference the only difference is that tens play a little higher sub range then twelves, twelves will play higher range just not sounding as good as tens. I personally have one 12", and it plays everthing no problem.But it will be up to you to tune your system with an eq or crossovers so that your sub will only get certain freqencys. If your crossover is set to 80hz for sub your sub will get all freqencys 80hz and down. Same with high's but they get whatever you set it and above for the most part. Im not going to get deep into explaining it all it just takes to long best bet is to goto a caraudio website and read about eq's/crossovers/ subfreqency and so on. The easy way out is get an amp with a built in subcrossover which most if not all classd's have.then just tune it to the music you like. the crossover on an amp willl have small dial that can be adjusted to let in or filter freqencys, the higher the slope on a built in crossover the better the filter. the slopes are in increments of 6 , 12 , 18, 24.24 being the best either linkowitsriley or butterworth style crossovers, sound confusing yet. Thats why you should call the 800 # that most companies have ask for tech support and tell them what you want to do. They will then help in that arena. Ask them what kind of crossover the amp has butterworth or linkowitsriley and at what slope if its at least 12db your ok.linkowitsriley and butterworth are just different styles of curcuit design each named after the person who desgined them. The only reason it matters is if you buy an external electronic crossover it has to match the amp, meaning if one linkowits and the other is butterworth they wont work together. most amps have a 12db crossover so if you buy an external 12db say audiocontrol just for sub it has to match, they will then work together to give you 24db slopes it just helps to control the sub better, for more precise sound.sorry for the long explanation.

my deck has a built in EQ and Crossover, i kno how to set the gains and all that stuff, i was wonderin if it would be worth it to get 2 10'' instead of one 12''

 
Rep Power: 0

that just comes down to design and space and remember 12's will play lower freqencys better then tens.

 
Rep Power: 0

so you would say that one 12 is just as good, if not better than the 2 tens?

 
Rep Power: 0

like how much louder will the SPL be with the 10s?

 
Rep Power: 0

no just plays lower freqency, people who tend to listen to r&b and rap and want a lot of bass would go with a 12". I guess if you add up the speaker area it would probably show the tens having more area, as for spl that depends on alot of things starting with enclosure.tell ya what pm me for my work #. Im here from 3:00pm to 11:30 I ihave nothing to do today so I'll have time to talk. Later

ok, so im gonna go with the 12''
but would the DEI 750d be too much power?
600 watt @ 1 ohm
400 watt @ 2 ohm

what is the rms (root mean square) or continuos power of the sub, its max rms power?

I would say its perfect for what your doing. It can be wired for a one ohm load to your amp which is perfect! The dei again would be my choice, we installed them when they first came out and we couldnt blow them no matter what configuration we put them in. Very durable and the power is good, Its o.k. that the amp has more power then the sub, just when you get ready to tune it put in a bass cd, then turn your amps rf matching dial or gain dial all the way down, then turn your radio 3/4's of the way up while the cd is playing then slowly turn your amps gain up until you hear distortion, then turn it back some till its clean. Thats one of the easiest ways of setting your amps gain to match your head unit for lowest distortion and highest power for the sub.

isnt there a real way to do it with a Multimeter?

and 600 WATTS is not too much power for the IDQ?

Im too lazy to type anymore so here get ta readen':
and no 600 is just fine.
