SQcomps install
hey, here's the thread I told you I'd start...
keep in mind... these are single 12's on this graph, 750rms once you put these boxes in a car, you'll have cabin gain in the sub 40hz range... especially in the sub 30hz range. the group delay matters most above 30hz, once you get below 30hz, it really don't matter the ported box would have a big long port (see it)... but that would be needed in order to ensure there would be no port noise at high volumes (which would kill your score in the lanes). |

Strange graph readings.
I would expect to see an amplitude peak around 3 db's higher on that ported box line, around the 40-50hz region. Every single graph I have ever seen, shows a FLAT curve for a sealed box, with a drop-off starting around 50hz, and a slightly higher peak in db just above the tuning frequency for a ported enclosure. And why would anyone ever want to run a GIANT over-sized SEALED box ??? Why not save space and just do a ported box?

that isn't an amplitude chart per say, it doesn't show how loud it'll be, only how quickly it'll roll off. the reason why it doesn't look like the ported box is a lot louder is because it is a small size ported box considering how low it is tuned... That is an extremely low tuning for a car. I'm trying to convince sqcomp to do something a bit more radical, yet easy on his install... I'd like to see dual 15's IB in his trunk. |

Sq you have a Sedan ? .....If so did you remove the 6x9's to get more sound out from the trunk....I have the base model....so my rear seats won't fold down....i'm flirting with the idea of seeing if there's a way to fit the fold down seats in there, with maybe changing a few bolts .

Sqcomp, if you start using membranes.... you will lose your 20-40hz octave... at least a good amount of it.

With a ported box, you have to have a awesome box design, or a 1/3 octave eq. |

As much as we all love our Yarii,
The Yarii's biggest problem is the fact that it is a unibody car. It doesn't have a seperate FRAME under it. All the suspension components attach directly to the body shell. So, naturally it transmits more road noise. It is after all..... an ECONOMY CAR. I do wish that Toyota would have spent a little more effort on sound-dampening. When you strip the panels off the car, you see how little they did. I mentioned this when I filled out my "Toyota satisfaction survey". But after all.... the Yaris is an ECONOMY CAR.

Dude that spare tire needs to be relocated..Lolll i see lots of potential under there for a nice lil amp rack setup. Imma see if that sucker can be moved to under the car, kinda like how trucks are.
Yo do you think a set of 3.5's with a Mounting depth of 1.5 will fit in them c-pillars ?

You think that stuff could be an alternative for the trunk, for us that are on a budget to get some " mass " and deaden the trunk a bit ? Ace hardware has it for 24.99 a gallon.

Sqcomp is right! I agree %110
I just started this process and every hour I spend it's worth it. I started to notice the benefits in the early stages, watch video: YARIS DEADENING VIDEO I'm only installing a small 10' sub-woofer not a big deal or professional install like you guys, so I'm really looking forward to see how your set ups come alive. .
