I installed the pods yesterday which was very easy and all I can say is wow!!! These things made a world of differance. It was like getting a whole new stereo. I should've bought these when they came out! I bought the hogtunes fairing speakers back in '06

 

I agree, they're probably the best audio upgrade you can make. I installed the Hogtunes fairing speakers and it was a bit better. About a year later I installed the tweeter pod and and it made a world of difference. The sound from the speakers is much crisper and less muffled at highway speeds. You can clearly hear cymbals and other high frequency sounds that you just don't get from the fairing mounted speakers.

 

I love my HogPod. I changed the 4 speakers, added the amp and HogPod and couldn't be happier. Music out of the iPod is crystal clear on the freeway.
