Hey guys I have read for 2 days on doing a upgrade on my 2011 JKU with the infinity stereo. I just ordered the 77kick10 for the dash and the sound bar both. I will be keeping the original HU and also the sub. Has anyone tried to use a Sound Damping material along with poly fil? If so could you tell a big difference with the dynamat?

I didn't know if a combination of the 2 is better then just the poly fil??


Thanks in advance

I stuffed the sound bar and the front speaker pods with PoliFil.

I also covered the out side of the front speaker pods with a DynaMat type product.

Mucho Better.

You want both for different reasons. You may also look to changing the capacitor in your dash tweeters so that they are audible over a broader range. Use polypropylene capacitors if you are an audiophile.

One of each of the following is enough to do the front speakers, the sound bar and the sub. You will use all of the hush mat and have a lot of polyfil left over.

If you have a stock sub enclosure, replace the stock sub with this one:

BTW, I have a slightly used set of these sitting on the shelf. I went back to stock alpine because they are better matched to my head unit and amp.

I'm keeping my head unit as well so are the stock speakers just as good? Also is the factory amp ok with the pioneer sub?

My suggestion is to start with the sound bar replace the speakers and Dyna-mat one side and listen, fade to rear then back and forth. Do you like the results, if yes then Dyna-mat the other side. Same with the poly-fill, one side then listen. If you find you like one or the other or both then do the fronts too. I just did mine and found the Dyna-mat made a difference but the poly-fill that everyone raved about made the speakers sound muddy. But this is just my opinion. If you keep the HU and after you change the speakers you find the speakers pop when driven hard you may have to replace the HU. I had the 130 base stereo and when the volume was turned up past 20 with the new kickers it started clipping the signal (popping). I replaced the HU and what a difference.

I did the dynamat inside the soundbar and inside and out on the front pods along with poly fiber.
To me it takes the twang out of the plastic pods.
Running hertz audio mids it seemed to make a difference to me.
