Say i get a 4channel amp that gives me these specifications:

4 Ohm RMS Power: 2 x 150 Watts @ 13.8 Volts

2 Ohm RMS Power: 2 x 300 Watts @ 13.8 Volts

4 Ohm Bridged RMS Power: 1 x 600 Watts @ 13.8 Volts

And i have 2 component speakers that has 100 RMS power each.
Whats the outcome of using a 100RMS power speaker to a 150 RMS chan?
meaning: 2x100watts on a 150 watt 4ohm channel.
any benefits from this?, good?, bad? heard if i turn up the gains i can blow my speakers, what exactly does this mean? just got into audio systems, never played with equalizers before.
thanks in advance!

 

What about the other two channels???

You said, "Say i get a 4channel amp" but you give specs for a 2channel amp.

To answer your question, it is better to be overpowered then underpowered, connecting a pr. 100W speakers to a 2x150W RMS amp is no problem, unless you turn the amp gain all the way up and crank the HUs volume all the way up.

To set the amp up, [no matter what the wattage of the amp or the speakers is] you start by turning amp gain all the way down, then turn volume on HU up to 70%-75%, [playing your favorite music] then slowly turn up the gain on the amp, you can keep turning up the amps gain as long as the music sounds good, when the sound starts to distort, [during loud passages in the music] back off on the amp gain a little, keep in mind with volume at 75% it is going to be loud, way louder then normal listening levels.

Remember, music is dynamic and the avarage wattage the amp is putting out, [even when volume is loud] will be far less then the 150W, probably less the 50%, and your 100W speaker will have a 200W peak, [max] rating.

Advantage of being overpowered is "dynamic headroom", the ability to maintain a clean, undistorted, signal during loud passages in the music, and you are far less likely to damage your speakers when overpowered then when underpowered.94

 

Nothing bad would happen if you run 150 RMS channel on those pair speakers. The power will be splits to each speakers. Just make sure you got the right ohm on the speakers to get the impedance on the amp. Turning up your gains will cause clipping and distortion to the speaker. IT will fry the voil coils to BBQ.

 

i see. the thing is i was planning to just get a 4 channel, with components first. then later on if i do decide on getting rear speakers (midbass) i'll upgrade them up on the 4channel.
