there are lots of posts highlighting just that, "adding some polyfil/dynamt/kilmat will have positive gains". This post is specific to the added bass kit:
Ya it should be noticeable. Here is a good write up.
Did you cross them over at all?
My four corner speakers are crossed over at 300hz. I ran them for a long time without, and with them crossed over, there is a huge improvement.
Which speakers? (I tried to find a post with them listed, but couldn't.)
I went with the Infinity, just for the price point. All four were $108 delivered. I may upgrade them later, but I am happy with my system now. It lacks super low end because I have no sub, but it still does punch.
I didn’t mean to poopoo focals at all corners, they are great speakers! I just noted more audio from the rear with this configuration, which was one of my main goals personally. Totally agree, center channel and rear pods are the biggest improvement and must do’s on the B&O. Good luck on your rattle battle!I finished my install of the 3 dash speakers (JLs that OP used) and the 2 pod speakers (focals that OP used).
It really does make a big difference in sound quality. I felt like the B&O system was missing some mid/low range and felt "flat" (I'm not an audiophile so I'm not even sure what the right lingo is). There is a huge difference with just those 5 speakers replaced.
I was having problems getting the electrical connectors to mate to the speaker so I ended up soldering the amazon harness that the OP references to the speaker, and then just snapping it into the factory harness. I also filled the speaker cavity with kilmat like OP suggested.
I was showing the bronco to two new people yesterday after the install and they both said, "wow, this thing has a great stereo system in it"...
The system is good enough such that I'm probably going to skip the key amp and new sub. I'd be really tempted to coat the factory sub enclosure with kilmat, stuff with the polyfil as OP suggested, and try to kill some rattle before upgrading the factory sub +amp. With speakers, kilmat, harnesses, panel poppers I'm probably in for $400 at this point and I can say that I'm getting more than $400 of enjoyment out of it. Not sure I'd get that big of a return on investment with the sub.
One other thing, I noticed the biggest improvement with the JL center channel replacement and the rear pod focals. If I had to do this over, I'd probably try focals in all locations. I know OP poopoo'd that config, but audio quality is probably a little subjective, and the focals I think pack a little bit bigger punch than the JLs. If you aren't upgrading the sub, you might get more enjoyment out of the focals...maybe....
Thanks again to OP for a great post.
i actually compared the Hertz, Focal and Alpines.
Fair. And probably expected ranking based on factors. Assume the Alpines, though muted, were a decent step up from the stock B&O though?
