Fellow Groovers,

I saw these specs and haven't a clue what they mean (power wise). What is it in watts RMS? I know PMP and RMS, but what's THD?

Output Power(THD 10%, 8Ù): 30W x 5CH + 50W(Sub-woofer)

Just thought of it, Total Harmonic Distortion 10%, I take it U is a new symbol for ohms.

Still don't know whether it is 30W PMP or 30W RMS.

THD is Total Harmonic Distortion... basically the lower the better the amp

Maximum wattage indicates the maximum power the amp can put out in some particular point of peak at some particular conditions. RMS is much more accurate way of describing pwer outputs; it is in a simple way, the wattage that the amp can supply to a speaker on a constant basis (or the wattage a speaker can convert from signal to sound on constant basis)... this is why it is also refered to as "continues power output"

basically look at RMS output of amps not the max power output
e.g. the kenwood 12inch subs are 700w compared to pioneer 12inch which is 600w, naturally you think kenwood will handle more.. nup... because the kenwood is only 175wRMS whilst the pioneer is 300wRMS... and as a rule, most amps measure RMS is half of max power, thereby you can connect up a 600w(300wRMS) amp to pioneer sub but only a 350w(175wRMS) to the kenwood

Just to answer question... the:
Output Power(THD 10%, 8Ù): 30W x 5CH + 50W(Sub-woofer) you got to have a look if it's Continues/RMS power or Max. power handling... Mostlikely it's RMS but even then only 50wRMS is pretty weak for a sub, the speakers will drown it out!

ohh crap.. sorry... i thought you were asking what RMS and sh#t was... ignore previous one!!

most headunits are between 7-10wRMS. All that crap about 45w x 4 is PMPO (peak music power output). if you're serious about having a great sounding and loud system invest in quality amps...the best thing i did was buy a cd unit with no amp built in...made me buy good amps and ive since never looked back!

The RMS (Root Mean Square) Value is equal to 2 root 2 or approx 0.7 times the Peak Value.
