sounds good, only thing is if you want a better sq you might wanna look at the AA atlas, not saying the dd is bad but the atlas is considered by most one of the top sq subs, AA is seeling off the last 15's too put it in the 2.5cf box and they will sound great, i should know since i own 2.

lol your pretty much right muddy...im trying to get a sports car and i dont want to weigh down the back and i dont need a rediculously loud system anymore ive proven my point. I just wanna get the 4 12s mic'd and ill be happy. The main reason i was thinkin about the DD is since i already have them it would be easier than trying to sell all of them and starting from scratch.

would it sound good ported tuned to around 33 hz? would the bass be pretty tight?

port them high like dd recommends. you'll be surprised at how good they still sound compared to other subs that are tuned high.

So you want a SQ system, huh?

First of all, you have to identify to yourself what SQ is.

Is it just some really clear tweeters that dont scratch your tympanies, and/or some mids that arent drowned out by the subs or tweeters? Or are you talking about some subs that dont just vibrate your seat and flex your roof averaging 60 Hz.

Ya this may sound funny, but to most it is a reality. SQ is so easily misunderstood, and almost always abused.

To me SQ is a flat response. Bar none.

This means that you will hear exactly the same sound as if you were standing right in front of whatever it is that was previously recorded, without actually ever being there. :-)

Take todays most popular 2.1 set up in car audio for instance;

What kind of sound stage do you have? This means, where are your speakers (components) located? Do you have rear fill? Does the cars interior affect a natural flat response, if so, how? Does your bass sound as if it is coming from your sub which may be located in the back? Are any of your speakers faster or slower responding in comparison to the others? Does your system sound in or out of phase? Did you know that most (over 99%) recordings do not transfer a flat response?

Just thought I would throw these out there for ya. Hope this helps you achieve your SQ fantasy.

I know I ve tried many times to get perfection, and well, I always ended up compromising, lol. oh well at least it sounds better than off the rack sales pitches, lol

good points. If i get the mustang i want, it will be 5.25 comps up front that are lower down in the doors, 6x8s in the rear deck and most likely a 12 in the trunk. Possibly kick panel speakers as well but im not really sure. The goal i am trying to acheive is a well balanced sound where all bass is tight and the response is quick. I want the system to get pretty loud but remain clean sounding. I am used to running just SQL and SPL systems so any advidce is welcome.

i'd dump the 6x8s for a 6" component set.. don't forget the component amp.. did not see one listed

btw.. i replied in the for sale section about the SX 15

i dont recomend you kappas with cdt, kappas have the tweeter too hard and with the soft of the cdt it will unbalance the sound, get a pair of nice polk audio speaker for backs and they will keep up with highs and mids with the cdt's

would using components in the back make that much of a difference over high quality co-axs?

i'd actually suggest just using a good midbass driver in the back.. then pair it with a great front stage..

midbass in back will not sound as good as having some coaxials or compoenets that can get low and provide good highs.

the polks will get ya some nice midbass and awesome highs, and price is great

in reality in a mustang there is no reason why even need s\any rear fill just get a nice set of comps upfront and then ur one sub in the back sealed and ull b happy but if u feel the need id get another set of comps for the back same type as the front not good to mix speaker types especially if u want to go for sq cause they all play a diff sound and what not cause there not the same speaker

if your seriously into SQ.. you will need some type of rear fill unless you have a truck.. then you might be able to get away with it. you don't need much just enough to be hear slightly. you want to be more concerned about your staging up front.. i'd suggest some kick pods unless you want to re-work your door panels :-)

Agreed Charlie:-) Unless you are in a large car/suv there is no need for rear fill especially is perfect imaging is what your goal is. In a perfect workld you will need time alignment and a excellent front stage all time aligned to hit your ear from the front at the same time, as if you were standing at a concert. A good component set and a w6v2 sealed will be fantastic, trust me I have run this system for a long time and was nothing but happy:-) another sub to try in a small sealed box would be a ID max or a SI mag.

hmm.. Idk how'd you compare the inside of my jetta to your car but I consider my car small and had an SQ judge do a run through on my car..

he said I needed a little rear fill but needed to concentrate mostly on my front stage. as far as staging in my car.. its not too bad.. just need to bring it inwards more but it is at least ear level :-)

the thing with SQ Kevin is it is different for everyone. That judge might like a little rear fill. I agree with a little bit if it is time aligned properly.

Jettas are great for SQ as far as interior shape is concerned, but I'm not too crazy about the front stage stock "locations".

i was going to get a VW GTI VR6 6spd .. but when I got quoted 400 for insurance I said the hell with it.. at the time it was either the Jetta or a Mazda6.. and well I'd rather have a Jetta. Personally I don't much care for the car but it gets decent gas mileage which my truck certainly did not :-)

i agree with Mixneffect 110%.

SQ to some people is a completely different beast than it is to someone who has heard a lot of systems, or likes a particular sound from a set of tweeters/mids/etc.

Anybody wants to state that Boston G5 would sound better than these:-)?
http://www.seaslotus.com/subwoofers.asp

Well Boston is finally doing the shorting ring (only one though) on their VC's, that's progress:-), about fuking time:-). However, Seas is still out of their league:-)

Muddy is 100% right about the "car audio evolution":-)

yeah seriously, when you first start all you want is loud, then loud becomes annoying and you want loud with detail, then as you get older detail becomes crucial:-)
