Anyways did the layout today, the amp and center sub will be flush with the floor as well as the enclosure will be the new floor itself... Just set the components there to get a feel for them and get some pics... WIll look allot better flush with the floor as you will see the greddy bar much better. Subs with have a custom made "designed by me" laser cut piece of plexi over them, the amp will be under custom cut glass with fans. Cannot wait! Amp in the photo is a DLS A7 and the subs are Image Dynamics no names "same as the ED 11OV.2" as id used to be there build house. Anyways great subs! Lots more to come soon as it all comes together.

 

Here is a pic of just the A7, man she is a sexy work of art!!!

 

looks nice. i like that greddy bar. i cant wait to build my box for my 10s

 

that's a big amp!

 

The DLS A7 is a monster, beautiful, powerful and clean. Internals are a work of art!

It is a 5channel with a 1 ohm stable class a/b sub channel which puts out around 600 rms. Plenty for me.

 

3 subs on 600 watts? i guess that'll do. But you'd get a LOT more output with more power. I mean, if you got 3 subs, you mite as well get the most out of em. Otherwise, 2 would probably do fine.

looks great though. That IS one big amp.

 

I am not an spl guy, I compete in sq. 600W across 3 subs in a hatch is more than enough for me and will provide way more bass than I really need. My last winning sq system had 1 10" in it with less than 200 rms to the sub. I am only doing 3 10's this time around for looks.

 

Damn, that is a sexy amp!!
cant wait to see the finished product

 

i hear ya. i'm an SQ guy too. Though i like my bass loud. It just seems a little contradictory, thats all. If you're about SQ..then why 3 subs. 3 subs "looks" better than two??? does looks really matter in SQ comps anyway? 600w thru 2 subs in the tc is more than enough for most. (i have approx 600 going to 2 10"s at 1.5 ohm mono) it just seems if you're gonna install 3 subs, you mite as well feed em some POWer so you can actually turn it up and maybe win some SPL too.

But enjoy. and lets see the finished pics.

 

So you think two 10's being fed 300ea is louder than 3 at 200 each..? "if you compare same subs same enclosure specs, 3 is always louder even with less wattage, less to a point anyways" Since you have to almost double power to acheive a 3db gain, 3 will be louder at 200rms each. 3 over two already start off with approx a 1.5-2Db gain advantage at any given watt.

Also like the post said, 3 was is for looks as the car is being turned slowly into a show car as well, 3 just looks cool and will be way louder than I could want to use for I am not a basshead by any means.

 

SQ or SPL, that amp looks sweet so who cares :-P

 

ha! Thanks. Yeah DLS makes killer stuff. Not to hard to get in the usa either!

 

great choice on the Image Dynamics. I have an ID MAX and I got 2nd place in an audio competition this last weekend. I was the only person there with only one sub and I competed in the 1-2 sub category. I hit 143.3 dB, not bad for just one 12"!

 

How do you figure 3 subs running 200 each is louder than 2 subs running 300 watts each? With three the waves are just gonna bounce off the glass and cancel out some of it with 3...

Love the amp by the way.

 

Dude, you just contradicted yourself AGAIN. I don't think that. In general, and with few exception 3 drivers will play louder than 2 drivers on approx. the same power level. its not about power, its about the surface area of the speaker cone. More surface area= louder.

But you seem to be jumping back and forth. First you said you were not doing it for SPL, but SQ. Now you're saying 3 will be louder than 2. But i thought you didn't care about being as LOUd as you can. If your not a basshead by any means, i just think 3 is a little overdoing it. Plus, at such low power levels, the 3 really won't play THAT much louder than 2.

As far as aestetics; 2 subs is Definitely WAY better than 1. But again, i think 3 is overdoing it a little. 2 says, i just like to bump the bass a bit, not rattle people out of bed. 3 says SPL competitor, to me anyway. Plus 3 being an odd number, its tough to design a system with any symmetry in your enclosure--which would be big points for a show car. I just think 3 looks unbalanced, like you're trying to stuff too many speakers in there. The tc's hatch is small enough as it is so also providing the necessary air volume for the three subs will be more of a PITA as well.

equipment looks good, but it just looks like your designing for SPL-though you don't have the power it. But you want 3 cuz they'll play Louder than 2, but you're more about SQ?? I'd be worried that the 3 subs will outplay and drown out your mids and highs.

please keep in mind, i'm not flaming, just trying to help you out by offering my opinion and throwing some ideas out there. good luck!

 

Desert heat---this is what i'm talking about. With ONE sub he hit 143 db's. You don't need 3 to get the kind of output i Think you're looking for. 2 would be plenty! Unless your are a closet basshead!

 

Uhhh... no I did not contradict myself, I was just responding to your comment about two vs three spl wise is all. And yes, it has to do with both cone area and wattage applied. Also these subs in particular are best at .7qf sealed each for sq which is what I will be running. I already have done all measurements and I get .7ea with ease "2.1qf total" I know the upfire is not the best, but I have to deal with it. Also 3 will definitly not overpower the front stage if it is tuned correctly. I won many competitions with 3 oz audio 250L's back in 1998 - 2000 and have been in the scene both at competitions and ces for years, So yes, I know exactly what I am doing. Look me up under desertheat under the caf forums or elite car audio. And to make it clear, there is nothing wrong with two subs, and nothing wrong with running three! Just personal preference. Thanks for the input, I planned this setup to have 3 and when it is done you will know why It is going to wicked looking. All to his own though!!!!



Also for the other guy... no, having 3 over two will not cause cancellation "my waves will not bounce off the glass and cancel some" as you stated. And yes 3 subs @ 200rms ea of the same make / model of subs in the same enclosure spec will be louder than 2 of the same / same enclosure spec @ 300ea. 3 will have 33.333% more cone area. Wattage / spl do not work under the same principals as cone area. Ah well .. Anyways.... *LOL* Will keep you guys updated on the progress!

 

def no cancellation. Only real way to get cancellation is if the waves are directly colliding head on ie. drivers facing each other in close proximity.

May have some funky wave travel patterns and reverb though with the upfiring off the hatch glass.

what are your enclosure(s) tuned to? 45...

 

You don't tune a sealed enclosure, a ported enclosure is tuned based on box size/port length/area. A sealed box, you can change the size to slightly move the place the box peaks but it definitely isn't tuned in the same sense of the word.

Plus, modifying box size to change the peak of the enclosure severely changes how the speaker reacts in said box. Granted, a ported box will change the behavior as well, but generally won't change the sound as severely as just...say...making a sealed box bigger to lower the tuning.

When building a sealed box, most people aim for a specific Qtc in their car of .707 which is the "ideal" box with the flattest response. Obviously putting this same box in different cars changes the response based on cabin gain though.

^^ that's a good explanation on Qtc

Looking good, we had a similar set up to that in our GTi once upon a time.

And 3 on the same power will definitely be louder, no way to really get cancellation as long as it's crossed over at 60ish Hz, at which point the waves are so long there wouldn't be any sort of cancellation in a tC.

The other advantage to more drivers in SQ competition is that they have more surface area, less distortion since to reach the same level(volume wise), each sub travels less.
