Woah thats insane, I was just ganna start up a thread today on this ..
I myself have heard and seen the Z-5500's and they are of true power and bass for sure..
I've read every single review and they are all positive.. I'm actually saving up to buy them in a few days , can't frikkin' wait to get these beast hoem and hook em' up.. The best part is the 500 RMS watt they have.. watt is something, but RMS is where the Watts are really at.. see the system can go up to 1010Watts, now thats just insane !!!! And by the way for anybody who has or will be buying the Z-5500, Turn the dial past the 10 on the pod, and it goes up another 10

so the 500 w its rated at actually can go up to 1000w, explaining why it says total PEAK power of 1000w.. tried it on my friends system and yea, you have to use the remote to turn it up, cuz if your anywhere near the system or sub, you'll blow your eardrums out. !! lol..
anyways, Take care, hope some more people comment on they're experience..
Go for it man.. Z-5500 are an Excellent Choice !

You mean the audio over drive which requires a full 360degree turn after already on the highest setting?i think most people know about it.
