It was a parting comment, I don't think he has citations. But googling now, it seems polyfill is 100% polyester which is fire resistant.
I installed a Kicker Key DSP amp and it definitely improved the sound, but mid bass still sucked from the door speakers. It turns out that the first installer did a shoddy job and the speakers weren't secure - they could move 1/2" and were rattling around in there - and there was no foam tying them to the door or the skin. I secured them and added fast rings to seal them to the metal and the skin, and the mid bass is plenty! I suspect I could have skipped the amp, but the DSP and extra juice is still an improvement. I installed a Rockford Fosgate shallow sub on the stock amp with polyfill behind it and it tightened up the subbass quite a bit, but it's not any stronger. I've gotten a little more power out of the sub by fading the sound to the rear about 30%, allowing me to turn up the master volume another 4 or 5 ticks while keeping the overall volume the same. It does shift the sound stage back a little, but I actually prefer being immersed in the music vs having it in front of me.Thanks Triaque.
After some more listening, I've noticed that when when a bass drum hits, the rest of the spectrum seems to get muffled... or something. A couple theories: 1) it's just a bit underpowered, and I really need an aftermarket amp to fill it out, or 2) the active noise cancellation is somehow picking up on it and interfering. Any ideas?
Where would I put it? And would I need to run another power wire to the battery? Agreed that the quality sound makes me like driving it 2x more.You could easily add a micro mono amp to hump a little harder. They are under $100. I keep telling myself, I am spending what on a mini van. I like to drive it and we go on road trips and I like quality sound.
Hi I have a Rockford Fosgate R2-750X5 and I’m trying to connect this to my 2022 touring. I don’t know where to start can you please help.If I did it over, yes, I'd probably get a 5 channel DSP amp to drive the sub as well. Could probably get a ton more thump out of that little enclosure - still only 8" but unless you're a bass head it should be plenty. I agree that the sliding door speakers are really lacking. Partly because the factory amp sends so much less volume to them, but I think mostly because they're so buried back there and it's such a large space. But I'm optimizing for the front row so it doesn't bother me much. Probably would have skipped replacing them had I known how little difference it would make, though I suspect I'd have the opposite opinion if I heard the blending of the factory speakers with the aftermarkets in the front
All speakersThis going to all speakers or just to a subwoofer?
