Ported Trunk

[AleroDrime]

I have two 3in ports, identical to the ones that were in my bandpass box, and I want to port the trunk. My original plan was to do this through the rear deck. But the metal part underneath and roods are keeping me from doing this.
I'm asking your opinions on placing the ports though the center of the rear seat. This means relocating my large amp but i beleive there would be a lot of benefits from doing this. Such as more bass in the front of the car and releived pressure in the trunk, less rattle and less hazard to the 6x9s.

I want your honest opinions on this mod, please leave opinions about me out

[Valley olds]

Just take out the 6x9s and Ta da you have 2 6x9 ports

[[ion] C2]

sounds like a good idea to me

[AtomicX]

Yah, thats the easiest way since the rear speakers suck.

[AleroDrime]

I really wanna have 6x9s in the deck that that leaves like two fake speakers.
Na how horrible would the seat ports look and do you think it could come out good?

[AtomicX]

Why would you want the 6x9, they serve no purpose at all.

[AleroDrime]

ive tried adjusting everthing to the front and beleived the sound sounded fuller from the front with the 6x9s working, and the music wasnt very pleasing form the rear seat with them off,
so in all my personal taste is to have working 6x9s, i might later put some in the rear doors but id still leave those two there

So do yall think it will look bad or that ports in the trunk woulnt really function like i think?

[AtomicX]

From the rear seats it wasn't pleasing? So? Last time I checked you are in the drivers seat.

how big is ur box

I don't know too much about this stuff, but if you remove the 6x9's you still have the grilles over the holes. You will not be removing them

its a Memphis box for Memphis 10s, its pretty deep and very heavy
note i took that towels out today theres no beaches at East Carolina University LOL

I don't see any benefit for SQ or SPL by doing this, is not going to be easy to fab, install or look right. Don't get me wrong, its a cool idea, its just to much trouble to get it right.

Have you d-matted your trunk?
Did you fix that gap on the outside over the plate between the metal and plastic?

That is an unrealizable goal. Speaker systems are a compromise.

The port idea should work, but will involve trail and error.

I'm confused with what you're trying to achieve. If you want better SQ, this is definitely not going to make it any better, if anything it will be worst.

If you're trying to get more bass, what you're doing is a lot of work for very little gain. The concept of porting is to allow the subs to work harder with less power hence more bass, but keep in mind that sound quality will not be as good as a sealed enclosure. Also, you shouldn't just create ports without consulting the manufacturer's specs for your subs. Do some research on enclosure tuning before you invest a ton of time and money into it.

At the end of the day you want to listen to music, not noise.

Not true, ported boxes just take more work and know how to make them sound as good as a seal box.

# 4 Ported boxes don’t sound as good as sealed

In most cases this is strictly a result of linear response vs non-linear response and it could go both ways. 4th order systems or “vented” boxes tend to be far more particular to volume, port size and length and the driver TPS’s rather than sealed systems. Misalignments are therefore amplified and greatly affect the frequency response. Often times in car audio, ported boxes are not tuned low enough, or the volume is too large and there is a large peak in the frequency response from literately too much sensitivity or SPL at a very narrow frequency band. The other issue is if the driver does not have enough BL or has too high of a Qts and becomes under damped at resonance. This again leads to drastic peaks at the resonating frequency; however in this case, the driver will be peaky there regardless of content and it will sound ultimately less dynamic and very bottom heavy. However, a well designed vented box may have considerably lower distortion and higher dynamics than a sealed box because of the added SPL gained from the port without increasing the active driver displacement requirements. Sealed systems evoke the most non-linear driver behavior to reach any given SPL, so in fact, they could be the worst sounding system if your SPL demands are considerable. It is important to model a ported design or ask the manufacture for a recommendation. It is also critical to include a high pass filter on the active driver in a ported box for protection.

i dont know much either about car audio, but i do know this when i had my grand am, it had 2 orion 12 in a sealed box which was ported through the package shelf
the installer made a port out of pvc, from the box to the package shelf, he cut a hole in the metal, i still ran speakers in the rear and the package shelf had a screen and a hole for the port

the bass was nuts!! it was loud as hell, and i remember hitting a 150db with this set up

this is like the first post that you made that makes sense

I beg to differ with the people saying the 6x9's serve no purpose. I have 2 6x9s in the rear deck and they are hooked up to my 400 watt interior amp. I also have them set on a .02 sec delay to run with the surround sound coming from my head unit. They serve a GREAT purpose. Anyone at A.S.S. 09 can tell you that my car sounds great and clear.

AR,
FORGET the backseat porting idea, there is too much work involved and your back seats will lose their purpose. The rear deck idea is the way to go. Just liike Bbdyman said, run a port from your box to the rear deck, cut a hole and voila. Also if you are worried about your 6x9s in the back because of too much pressure, get some speakers condoms. I did that when installing my system and it made a world of difference.

I think thats a joke but a durable plastic piece to fit underneath the magnets and protect them from pressure and foreign objects underneath does sound like a good idea

I had an 86 grand am that came with baffle boxes over the factory 6X9's on the rear deck. Nobody believed I had stock speakers. The baffle boxes worked great. And dude, until you can figure out how to run an intake, I wouldn't worry about trying to port the trunk
