I like the idea of an wall behind the c-pillar very much , 2 less windows and 1 door less that are going to flex and woofers are not playing directly to the roof , maybe even a chance to brace that same roof with that wall , the rest is the same as a box behind the c-pillar ...........regardless of what other people think.........build it well and it WILL pound ....... @bassahaulic , +160 db in such a wide range ..........Yes we need proof !

Nice build , wondering why I havent been following this from an earlier stage . Very nice box and ports !

use whatever bit you want , take your time working with the router and dont go about it to fast .

no need fo scream .......they normally just reappear ,shouldn't take to long , patience is a virtue

so .... a transmissionline for 2x18 would fit ?

If the rear seats would be out a 2x15 might just fit nicely .....single 3kw amp , batts in the back ... should be within budget real low tuning and competing generally don't mix well

As promissed , I've run the numbers and came to the conclusion that 95Honda is absolutely right , these woofers are far better of in a vented or sealed enclosure . 3,5cuft tuned to 33hz would be fine , just make sure you don't make a trunk rattler ..so sealed it of from the trunk and directly play into the cabin

didnt mean to be rude or bash the whole idea .........but if you're gonna do it , do it right !

what kind of BS boxcalculator is that ?and even that you're not using it right , read the upper 2 sentences again . sure..............a passband from 26 to 70 hz but how linear is it ? Why an F3 of 26 hz ?

a lot of concrete and thick steel helps , some basic understanding how to shift a soundwave 180degrees helps too , and how to get that at the meter ......25Hz damn thats low ! an spl style box (which is not really a box) or some kind of hybrid horn where I come from we have a saying : Beter goed gejat dan slecht bedacht ! which basically means it better to steel a good idea than to think up a bad one ! so if your not able to make your own plans for an install that will do numbers like this , steel em !(or buy it...probably a little more ethical) look on the internet and find a car that does these kind of numbers and rebuild that install , sounds easy enough doesnt it ... hint : 48 SA10's ....

I think you underestemate the sound coming from a 12inch or a 2x10 inch setup , you really want to look into a bandpass box ,bass that lingers in your trunk is not a problem that is solved with more cone area , although that is the solution most often used .

doubt you'll srew up the sheetmetal in the trunk just to put in a few woofers , having a car like that , a bandpass enclosure just might be for you Space requirement will be an issue , for musical preference I personally favour a 6th order bandpass over a 4th order bandpass enclosure .... 2x 12 if you have the space ... BL if your going 6th order .

would depend on how he hit the curb and what kind of weight are we talking about ? keep in mind that cars are not build to slide against curbs whith all that weight on one point ... this just might be easier to fix than a frontal hit..

how about telling us what kind of vehicle you've bought and how much space you're willing to sacrifice ?

X2 some VERY knowledgeable people here a lot of official brand forums that allows you to speak to the guys behind those company's

I suggest playing a test tone cd , testing if it happens on a particular frequency , this could mean there is a wire power wire making ground that is hanging in free air most of the time and makes ground when it resonates ...probably the wire got accidentally moved when installing the other HU . please get rid of the electrical tape , there are kinds of tape what come loose in cold weather ...normally got something to do with how old the tape is and stiffness of the tape itself , the only good tape is the super soft one you have to pull untill it turns grey , that stuff will hold forever .

indeed those things are ugly ....

what volume do you considder a door , an SUV obviosly has bigger doors than a mini cooper T/s available on short term ? definatly looking in to these , still undecisive on kick drivers .... found an fullranger that might do the trick after a small mod , but this just might be the better choice . subscribed .

I'm very pleased with my Dunlop sportmaxx at the moment , used to have toyo proxes t1r's , pirelli p-6000 and the zero's ... like the dunlops much much better in the rain ... obviosly not the same model as posted in the initial post , positive feedback on dunlop !

good stuff ! , be sure to post those pics up !

the whole idea is that SQ everything schould blend perfectl have a flat response and be in tune with the rest of the system , it would not play notch louder than the front speakers at the ear .thats what the debate is about . thats why you shouldn't use the term SQ when a woofer is going the used playing louder than the rest of the system .

Both very nice amps , flip a coin and choose whatever you want The amp wil have very little to do with the SQ of the driver , wouldnt worry about DF or low impendances , the box and placement of the box will however have a great influence . and how would 4ohms be easier on the electrical ? a 1000 watts is a 1000 watts ... not setting the gains ideally but a tad lower and the power advantage of the sundown would be gone .... furthermore I wonder what SQ setup "needs" a Kw for driving a sub , I mean it nice to have overpower for dynamics and cooler amps perform better but needing it ?

no , the fit of the box is very tight ,awkward angles and no tools to fabricate those in an easy way , aeroport also proves to be a bigger challenge than that I had thought , havent had time to build the last couple of weeks because of the hollidays with family and all that stuff . Installed the peerless 3inch driver in pods on my A pillars , but only for testing , they're playing free-air right now : baflle on a piece of 4inch long HDPE 5inch tube , filled with longhair wool and open end . liking it ,but testing them in a 0,8 litre closed boxes shortly . did an install in one day for a friend some weeks ago .. at the end of the day the Alpine 9855 turned out not to be working ..... bummer @ 10.30pm wanted to post up pictures of a car I've done with a morel comp and Fi Q high Qts , and although I made the doors , the mounts for the mids on the dash , the enclosure in the trunk and side plates in the trunk to house a bunch of stuff. butt he won't let me post up pictures ,he wants to keep it secret (I know its childish) so the competition in the SQ field don't know whats coming (in the sense of how it was made) .... to bad I can't post those pics up . and the fully done install could take a while ................

The reason guns shouldn't be sold at every corner of the street to every nut.....

So you ended up spending no money exept for wood ? Tip: make a double baffle and make bracings to stiifen that box up
