Nice job wit da photoshop bro.

 

this is also a decent Street C score................

 

Nice job. Did you ever finish sound deadening the car besides the doors? And if you need more port tuning length mount the ports inside the box further. Also you plan on trying a 9" port? I expect this to be as loud as your car last year. lol

 

We've only done the 2 doors on the vehicle. Haven't tried the floor yet as we don't know if there will be a gain. Also we haven't done the roof either. Jeff I hear you had a golf. Did you try to deaden the floors and the roof? If so what was the outcome. Was it a loss or a gain for you?

 

yah man we gonna try to mount port more into the box next, i remember you saying something about that a while ago

i think with 3 10's this car would be louder than mine was.

 

Now you're the one with hopes and dream faddah.Louder than your rex??? I wish...All hail the Faddah of Yuli:

 

good job guys! alot of hard work is obviously paying off yet again....you are going to be hard to touch @ finals....

 

if anyone is taking anything from this thread it should be that spl gains come in small increments.

 

believe me, Im watching,learning taking notes and such....(as I have almost the same car) lol

 

I had tested a golf similar year to yours but ended up owning a 02 golf with a 50hz tuning frequency which made it suck for spl but it was loud (154 street A). As for deadening your roof I highly suggest it especially if it's flexing a lot. If you do the roof "right" I see no less then .5db gain coming from your car. And when I mean doing roof right I suggest investing in something more stiff then something like dynamat extreme.

Reason being is due to your lower tuning frequency with a something like dynamat extreme it could have an adverse effect and cause more flex due to the added weight and that your roof is flat with no arch. This happened in my 02 golf when I double layered the roof. It lost .5db because with the extra weight the roof would actually move more and cave in causing some cancelation. But also keep in mind that the extra flex was also contributed to the low tuning of 50hz.

Now with my yaris of tuning of 55hz (similar to yours) I gained .6 or .7db doing the roof. Higher tuning less flex probably helped too. Also what may have caused my golf to flex to much in my 02 golf was the roof was flat with no arch unlike my yaris which has an arch in it. If you don't know having an arch is added strenght unlike just a flat roof like in the golf. That's why I suggested something more stiff as to avoid the flex since I know your golf has a flat roof. If you could get enough vibraflex (or what ever murilo used) to do your roof that would probably be best choice. Not saying reg dynamat extreme won't possibly work cuz it probably will but with you having a flat roof if you do you might as well do it as best as you can the first time rather then do it over later.

As for the rest of the car go crazy doing everything with reg good thick dynamat extreme or something similar. It may or may not gain doing the rest of your car but it for sure couldn't hurt. Also if you do invest in the vibraflex and it works on your roof I would suggest doing your doors with it since it's very dense.

Good luck and glad it's your coming so far with the golf.
