I mat heavily and tune low. Windows up it's quiet, but windows down it definitely comes out. My Volt has a hatch and both ports are firing back with my 6th order, so all the sound comes back forward.
I love it! Your deadening and low quarter wave totally make the bass alive when the windows roll down! 6th orders also help with the loading when built correctly! Thanks for sharing!
I have a big b pillar 4th order with 6 15s doing 160db at 42 and 155db at 26hz. Can hear mine about 2 miles away with windows down and even on low power rn. In a 98 yukon.
At slam this year the southern thunder tahoe had 8 15s on 30kw. And it was SUPER loud outside the car, because the doors were rattling and everything in the car was shaking. Right next to it was the Gately Slam Halen. It's got 6 12s on 18kw. It was way louder inside the truck, but it was almost quiet on the outside. And I think it's because slam halen was a smaller cabin with absolutely no rattles. A more extreme example was when I went to Usaci finals. I stood next to Carlos' van Delilah when he did a 180 db burp. And I had to ask him if he just burped, because it was quieter than the systems across the building that were playing and testing in the mid 150s
I have absolutely no experience with those systems but I imagine that you’d want to be as quiet as possible on the outside. Because that’s lost sound that could be increasing your spl inside.
Y'all are both right. Honestly it's a testament to how much work and effort has gone into that van. It's the most impressive thing I've seen in car audio
has absolutely nothing to do with cabin size or sound deadening. All the cars ive heard including my silverado were louder outside because of huge windows and strong door panels and solid roof. All japanese cars / newer cars you can barely hear outside because theyre made with thin sheet metal that vibrates a lot and cancels a ton of shit out + small windows. Dashboard shape affects this too.
But yea every car is different. I have a dodge caliber with 2 8s sounds amazing and low inside the car. But outside was very underwhelming. In my truck 2 8s sounds so much more louder outside the truck. Definitely the vehicles resonance plays a big factor
I had 2 12in skar vxf and 3.75 cube box tune 33hrts sk 3500 amp played 20 to 38 hrts so loud but 50 hrts and up like half volume so got kicker 12l7s louder in car but vxf very loud outside car I was not happy I think morder force had a lot with that
@caraudiolab I'm still experimenting to see what works. I have an old school phoenix gold bass cube. I keep it dialed in on 27hz. That's my low peak. High peak is 51hz. I epicenter that. Me and my volt love the lows, lol
@@BigYank33700 Modern decks do a lot of system processing now. I still think they can help quite a bit depending on the source signal. My buddy swears by them and he ran a car audio shop for 20 years. I am actually looking at adding a DSP to my van build but am still deciding that. I haven't used the original bass cube, personally but I know Phoenix gold is awesome stuff! I still have a couple of their amps, call it nostalgia! They were my dream amp back in the 90's! lol
With mids/highs, its more about having them close to the window so the sound isn't getting caught/cancled/muffled in the vehicle before it exits. But, it is possible that something like a compression driver might help. I haven't done enough testing to really know.
There are tons of shows in Southern California. It has been a long time since I have been there, but plan on resuming going to those shows sometime in the future.
My boy had an Old Civic With 2 JL 12s Dynamat with great amps and that thing was loud Asf on the outside. I have an HHR with a similar setup But it does not get super loud on the outside. What could be the cause to this? The shape? Also, how would a car like a Ford flex Sound on the outside with a nice system inside plenty of power considering how that car is shaped?
Thank you for answering my question !I asked for it because here in Tahiti, the objective is to transform your car into a portable speaker and play music for all the people present , here for you an exemple : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-65m6XoJp1m8.htmlsi=IAGpK68DmwElZDi9 Most setups have their subs facing foward and I was wondering if it was better to have them facing the back... what do you think about it?
Thanks for the video! Facing subs forward for higher bass (like maybe 40hertz to 100 hertz) make sense. This is also louder in general. Subs preform better in that range in general. It is the conventional norm. Facing the subwoofers backwards is better for lower bass, like under 40 hertz. This depends a little bit on the car size and length, but typically lets the bass wave better form because of the length. I don't know if rebassed music is popular down there, which specializes in lower bass. If not, I can see why they face subs forward. However, I have tinkered with actually facing subs backwards using just enough space between the vehicle and box to let the bass wrap around the car like a port that it gets stupid loud. However, that tends to happen within a range of frequencies. equipment
@@dqmnjohn_4491 I can see that my comment got cut off. It really depends on your equipment, length and the music you are playing (for frequency purposes). However, I think if you are playing regular stock music, maybe a parallel tuned (not series) 6th order double bandpass tuned to 45/90 hertz may be an awesome option! Get a sensitive sub with a higher fs with decent power handling for this application. If possible get the Sundown Uv1, for this, they are on sale for $300 american. This is a great music/spl sub that is almost half off right now because Sundown came out with the version 2. However, if you already have your subs, no worry. you still have lots of options!
Rebass music is popular here, (less than 40hz), but I'm afraid the build lacks punch, (I love low bass but I also like when you feel a kick in the chest ...) I'm fickle I know hahaha.
Probably which ever one is louder in the vehicle, if they both peak at the same spl, I would say the 6th just because it would have a greater bandwidth that would appear louder over music than the ported flat wall.
@@TheGamingChad. That completely depends on the goal of the 6th. Facing forward is used for demo and daily builds because it pressurizes the cabin evenly. Subs facing one side is used for competition, because it pressurizes the side of the cabin where the mic goes and gets a louder better score there. It can also be a good daily or demo build as well, but usually competitors do that.
Completely agree! I wanted to show off so many years ago! Now, I enjoy the bass being contained to the car! I only want to show off when I am at competition!
