Technical Pro
Ok i want to buy a 4100 watt home amplifier from Technical Pro but i want to know if it would really deliver?
i have 2 15" 4ohms 1500watts subs that i want to connect but i want to know if it actually will use all those 4100 watts, or what will happen to those leftover watts. Dose that mean it will deliver 1500 watts to each speaker???
Well i want my system to BUMP!! As much as possible (im a BASS freak!!)
An amp can deliver rated power at some rated distortion level into some defined impedance. Technical Pro rate their amps as total peak power. Their "4100 watt" amp, for example (link 1), is rated as 2x670 watts (rms) @ 4 ohms (or 355 watts @ 8 ohms)... a lot less than 4100 watts! The distortion level for their amps are not listed though, and many mediocre amps are power rated at higher distortion levels than quality amps, so it's possible these amps would be even lower power rated by some companies.
You say you are wanting to drive 15" 4 ohm subwoofers. Many subs have their own amps, but certainly an external amp isn't unusual. And a powered subs in addition to a main amp for the main speakers is common. You don't state what your intent is here though.
That said, the 1500 watt rating (likely peak, not RMS power) on the speakers is the maximum power the speakers can handle, NOT the amount of power they require. It is better to have too much power than not enough.
The amp and speakers should work fine together since the amp and speakers are both rated for 4 ohms. That said, there won't be any leftover watts. The loudness of the speakers (and the amount of power used to drive them at that level) will be dependent on the volume setting. It could be that you will use 2-10 watts for a reasonable loudness (hard to say since efficiency of speakers varies widely).
Keep in mind that loudness is not linearly related to power. See the 2nd link for a discussion. Bottom line is that it takes thousands of times the power to increase loudness by as little as 10-15X. So at all but the loudest setting you will be using MUCH less than full power.
Note that Technical Pro is exactly that ... a professional amp. While it can be used at home it is more normal for more professional use. Stability and robustness may take precedence to strict audio quality.
Hope that helps.
