@evilguy: the hi fi button only works when selecting 2.1 channel only. press the 2.1 button and then press hifi. you should be able more fidelity and more bass when using the hifi mode instead of the 5.1. selecting the mode will only produce sound from L/R nd sub. use this when your input are from tv or from two 2 channel source  and if your ears prefer more fidelity than surround sound.

yes, i do wanted to know how to turn on that thing, since i already lost the instruction manual when i bought it, i doesnt know much about the enzo spec and info.
can someone scan the instruction book for our reference?

lower the volume,
check ur cable n power supply

claim your warranty first if its still in the warranty period. enzo 7000 really test out buyers luck, my subwoofer is out right after the warranty period is over, if there is any faulty just claim your new one.

if its over try switching though various input mode, lets just hope that your reciever doesnt have any problem.

same here, my decoder goes pop and then then it wont wtich on.
before this my sub is dead and the decoder is burn, so my enzo is a piece of garbage now. still thinking of salvaging the sub...

Are all of these incidents attributed by low Quality Control?That's why i always avoid Sonic Gear since their speakers are just too darn cheap
