Metered the truck for the first time last weekend


Recommended Posts

might give subs firing up and ported towards the passenger side a try.. works relatively well for a 2 12's setup in trucks

This but ports should be firing towards the drivers side, not the passenger side. For SPL port towards drivers side has always metered better in every vehicle I've tested that style orientation with.

Alright! this is discussion I like! keep em coming lol

everything's appreciated :drink40:

i've tried every port orientation imaginable in my s-10.. for metering on the passenger side firing towards to passenger side has always been louder

This isn't teeball. YOU DO NOT GET A TROPHY JUST BECAUSE YOU SHOW UP. Put the work in and then maybe get the respect when it has been earned

oh also mines an aero port firing along the bottom so for a slot i'd do the bottom as well

I might modify this box, I can get pass side port at the bottom and subs up if I put a new baffle on the front to cover the sub holes, and then remeter.

Thanks for the help guys, I wouldn't have thought of pass side port.

So to update this, I did in fact redo the port and sub oreintation. I went from 11.2 in/foot of port tuned to 30 hz to 14.7 in/foot of port tuned to 36 hz and have the port firing towards the pass side rear door and subs facing the roof.

Hopefully I can remeter tomorrow with pioneerforlife, but after a couple hours of playtime and having a buddy listen to it. The concensus is that it sounds much much better.

I have gained some power handling in the subs, I can now play well into the high 40hz range, but get this, it will now play down to 26hz with more authority and is able to play down to 23hz (although it does drop off after 26hz) so even if it meters worse than before, it sounds better and that's my main concern, with spl #'s more as a curiosity

I see he didn't update this lol. Well with the modified box, it meters about the same. But it sounds so much better. He tuned higher but can play lower lol.

I think it just has to do with the way the port is firing (towards the door). This truck has been difficult imo. Everytime I hear it its louder but meters exactly

the same haha.

but the modified box is killin it (and killin the back window lol)

im surprised it meters the same... anytime i've tested port up port to the side has always been louder with 2 12's lol

Thought I updated this, whoops my bad lol but hey it is what it is with the meter. It sounds a lot better and the bandwidth is much larger.

Iirc the rta on the term lab was relatively flat at 1/4 volume from 30-50hz, didn't really want to crank on them during the test tones anymore than I had too, because I have literally beat the shit out of these subs lol

All this setup has to do now is last till next summer :) P4L knows why .
