How to Improve OE Sub Bass Quality and Eliminate Vibrations

[Tripjammer]

I added the second skin layer on top of the DynaMat extreme last night! Overkill I know but wow sounds even better. Base is very punchy with no rattles! Make sure you have a roller when your applying the Second Skin! Stay away from the wires and Battery and you will be fine!

Just curious how everyone else has been able to see what they were doing through the vents. I am doubtful mine is spread out very well

Looks good bro! How does it sound? You will need some DynaMat or Second Skin to line the trunk to complete it

@Tripjammer that really looks nice and clean! I bet it sounds the same! Good work!

Bro sounds epic!

I don't think you need to get it perfect. I felt like I hadn't done a very good job of it, but it still made an improvement.

If you are using the Weathertech rear mat, it will block most of the ports. I don’t know much about stereo tech, but wondering about adding another set of ports up by the subwoofers. Any thoughts from those who know more about the ins and outs of enclosure porting?

I would simply cut the rubber mat around those exhaust ports...

The primary purpose of those exhaust ports added to the narrow rear panel is to provide a release of exhaust pressure which exits from the 3 elongated exhaust ports located behind that panel (they are not "tuning" ports)....This alone provides a lower / less distorted bass response and eliminates those low frequency vibration and rattles...

Damn that sucks! Maybe cut holes in the WeatherTech Mat? I think you will be ok with how it is? How does it sound?

The OE Supra mat works perfect! My trunk is complete now!

Mine sounds good, but I did it right after purchase... didn’t spend much time in it prior to the upgrade.

Does anyone have any link for the speaker mesh to buy? Do you think fabric mesh would work around the port holes or would that impede the flow of air?

 

[Juggernautjoe]

Did the fix a couple days ago. Looks like I put the holes maybe a half inch too high. Still sounds fine. I also cut my weathertech mat to clear the holes. I'm gonna have to clean it up a bit.

Has anyone here replaced all the front speakers and rear subs with the bavsound upgrade ? I’m debating giving it a shot as it’s $1100 for everything. I would still add the ports to the box since it wouldn’t hurt. The factory amp I feel will be the the only issue
