Actually, my bro Keith just showed me the kenwood home system he just set up... it's rated for 100x5 as well, but it's blatently obvious that it's not 100RMSx5...
Ha, it only had a 2.5amp fuse in the back... so 100RMSx5 couldn't be continuous anyway... lol..
Do you have a link to info on the law and the specs the manufacturer has to follow ??
I'm definatly curious !
has to be 100watts RMS power or they can't state it. There are laws for home audio.

CondomBoy:
I have beefed up all of my in car speaker connections with thicker wire then stock...but most of the speaker installations from shops that I have seen used the factory cables in the car...pathetically small.
I doubt there would be much of an audible difference and I beleive it not to be of concern in low power levels(100watts or less).
Perhaps I am wrong?

home audio differs from car audio in the way of
power ratings car audio can be advertised in max power ratings the only governing factory is the manufaature has to print the rms ratings in the owners manual, however they have been known to print them @ 14.4v and leave out the 12v ratings.
home audio however is governed by csa regulations
and are required to have the only rms ratings of the product either on the unit/box/manual.
the fuse on the unit is for protection of a short in the unit itself.
110v and 12v are two different aspects however wiring the spkrs with better quality wire i found makes a difference especially if your spkrs are across the room and you have 30' of length!!
if you see some of the new gear coming out in the next little while head units primarily alpine
instead of having 50wx4 on the box it says 17wx4
regulations are coming
no more wool over the eyes for the average consumer!!!!

As far as receiver ratings go... from what I have been taught by various manufactors -- typical RMS rating receivers are done by running a 1k hz tone through either one or all channels at 1% THD. Most manufactors use the 8 ohm rating, while some will use the 6 ohm rating to show higher power. In my experiance, these power ratings mean nothing -- the more important factor is if the receiver's power supply is discrete or not.

If I stumble across reference to the regulation for home audio power I'll let you know but it's not worth my time to go actually look for it [img]graemlins/dunno.gif[/img] Should be easy enuf to find or ask on any HT website.
Actually, it's supposed to be changing to so that they have to rate all channels driven at the same time with a full range signal [img]graemlins/thumb.gif[/img] Look for a lot of sub-$500 receivers to suddenly go from 100x5 to 50x5 or less [img]tongue.gif[/img]

In the states it is regulated by the FCC.
As long as the unit can hit the state spec than it is legal. Doesn;t matter if it is one, two or five channels driven.
What they shoud do is show the wattage, thd, # of channels driven and at what ohms. If every manufacture did that you could then use that spec to compare. As it stands it is just another useless spec.
Haunz, the current draw listed is a much better indicator of how much power it can produce.
