Utiadam - Thanks for the photos. Do you think it was worth it to Dynamat the speaker enclosures and add the polyfill? Was it a profound difference or just one of those 'while I've got these out' sort of upgrades? Did the Dynamat add any additional width to the enclosures and did that cause any problems when you went to slip these back behind the dash for reinstallation?
Thanks!
I will give you my answer (opinion) because I did the same thing, but retained the OE speakers.
I think it was a
profound difference. I ride with no doors or windows year round and now the sound has bass you can feel and I can turn it up louder with a lot less distortion. These are all my observations not lab test results and that's what matters to me.
I stuffed the PolyFil in the pods and the sound bar so it still had some room to breath. Meaning, it's not packed in there so tight you could'nt get any more in there. I mention this, because I've heard people say "jamb as much as you can possibly get in there" and I've heard 'lightly fill the opening". I'm somewhere in-between.
I used the standard 0.067 DynaMat on my pods. I don't think it made it any harder to re-install them.
