what kind of mods did you have to do the civic kit? did it just pop right on?

 

Two comments


First, looks nice!!

Second, you would be better off running those 2 10"'s than the 2 10"'s and 1 12". They will end up cancelling each other out because of the way the notes will come off of them. I am sure if Brad or Hoss reads this they can explain it in better English than I can. Half the time I explain it to someone I leave myself wondering what the heck I just said.

None the less, it still looks good.

 

all you need to get the civic one to work is some sort of adaptor from your maf to the pipe....they sell two kinds one with a 90 degree angle and one with a lesser angle...i used the one with the lesser angle. not sure if the 90 will work in the fender or not....and bout the subs i dont know. this is interesting and hopfully i will find an answer soon..but it is louder and beats harder....hopefully im good....

 

Im not sure I Remember completely how this works, it has to do with timing. The same frequency will be produced at slightly differenty times off the 10's then the 12's.

 

I remember a few years back a kid at a comp. had (2) 8", (2) 10", and (2) 12" subs in his escort and the one Treo 15" I had hit harder then his six subs. All I remember is that it did have to do with the frequency produced by each sub. The guy who helped me get started told me about it.

 

please keep it coming with info on the subs because this idea is all new to me

Just a question, but do the subwoofers have seperate chambers????


12v rep, I think it's hard to say if the subs actually cancel each other out...

It's not hard to say..."the subs cancel each other out". See, that was easy.

It has to do with timing, frequency and one more major factor that escapes me. It is much like when people run a pair of subs with seperate amps on them. You have to match the outputs to make them hit in phase, if not they sound like crap. It is gets a little complicated when you start changing basic factors of an install.

 

yes the subs are in seperate champers...and afi292 thats all i noticed..it was louder and rattled my trunk more.

 

well, since 12Volt_Rep is a sales rep for pioneer and a proven installer, I would have to say that what he has to say has a little more weight to it.

If you look at wavelengths produced by different subs, you'll see there is cancellation. why do you think that SPL contest winners only have one size sub?

 

Im not gonna be an ass But it will definatly cancel themselves out. In realy simple ideas its like two little drums and one bigger drum. What are you gonna hear more? The bigger drum but its got back noise which are the two little drums. It also has to do with the sound itself. The bigger the sub the longer the wave lengh and longer wave lengh can be heard for longer wheas not as well as the smaller wave length. So if you have two different wave lengths not at the same length they are going to collide and cancel each other out.

 

But if you had 2 different amps and you had a equalizer you could use the large one for ultra low freq's and the other two for just low freq's. I think that should work.

trojan, since everyone here discredited me, it means we're wrong for saying that it's louder.

You mise well give up, and rebuild that sub system that you probably spent a good number of hours on.

Come on people, Trojan and I BOTH heard systems like this, and we both AGREE theya re louder... Rep, 95Ford... you guys are right in theory they would..

but listen, if you would please..

Do both of those amps have their equalizer settings the same? IF they were both the exact same amps that put out the EXACT same specifications of the sound, then YES they would probably cancel out ...if they do not cross over at a point, they will not try to play the same frequencies, and will thereforth not cancel out.

but until you equalize all the varables--im going to have to say we're right, and that it is louder. I am not saying its the way to go, im not trying to condone building systems like this, but im just trying to say its louder.

so...when you use the term cancel out. do you mean that my 2 10's would be louder then the current setup? because im a little confused. because my trunk rattles a lot more and it sounds better in the car. im not saying that you guys are wrong i just want to learn more about this..thanks

 

It rattles more yes because its moving more, but it "cancels" out the sound of the smaller subs with the bigger one. Though after doing some research it doesnt really cancel them out, its just muffeling them because the 12" has a lower pitch then the 10"s. If you want to make them work best I think you should look into a equalizer, seperate the really low frequencys to the 12" and then just the low ones to the 10" subs.

Why not do a little in car testing. Run just the single 12" for a while and see what it sounds like and then run the two 10"s. You have three options to choose from. Take what you like best. I'm probably never going to hear what it sounds like, nor most others here. Go for what you think sounds best.

thanks for all the imput. i will look into an equalizer after i get some info on them...and d_sellers1 good idea i didnt even think of the lol...and back to the equalizer thing. couldnt i just change my crossovers on my amps to let the 12 get really low and the 10 to get lows
