Hi all,
I have the HK system and I personally think it sounds pretty good for a stock system and even compared to some aftermarket. Could be a little "clearer" but pretty darn good as is and plenty of bass for me. Just wondering if you've done any simple things to it without really replacing much to get a little better sound quality? I was thinking of dynamatting the doors and rear speaker panels. Anyone do just this, no other changes, and hear a difference? Didn't want to go thru the process for nothing. Any other tips?

Adding sound deadening material usually helps-
Dynamat extreme and Cascade Audio VB-2 or VB-max are common choices.
