Question 1

How come it claims to have 200w but in input power is only 40w (18v * 2.2 A)?

Accepted Answer

Chelsie missed the intent of the question.  Yes the input power is 40W and I think the person asking the question knows that. The question was how can it produce 200w of output power from 40W of input power.  The answer is that the 200W ratings given are dishonest and violate longstanding US FTC regulations that requires that audio amplifier output be advertised as RMS watts into a given impedance (typically 4 or 8 ohms). What is being quoted here is instantaneous peak power which is NOT RMS power.  The steady state continuous duty RMS output power of this amplifier is probably on the order of 10 to 15 watts per channel with the rest lost to heat.  Save your money and look elsewhere.  This unit can't create energy out of thin air.

Question 2

Will this amp power 4 aura bass shakers?  50w 4-ohm each. recommended wiring would also be appreciated. thanks.

Accepted Answer

I think you would need an amplifier for EACH Bass Shaker. This is mostly due to the fact that this amplifier isn't capable of producing 200w RMS, plus you are going to run into Impedance issues too.

I'd probably just buy a used & completely separate (A CHEAP OLD MODEL) 5.1 reciever. Then put it in "5 Channel Stereo Mode", & run individual RCA inputs, & speaker wires to EACH channel in question. Obviously making sure the amp makes enough power to run the Bass Shakers. Does that make sense?

Question 3

Looking to power to aura bass shakers will this work? And do I have to run them in series? What should the crossover be set to?

Accepted Answer

Should work, wire speaker  individually set at 4 ohms.

Question 4

Hi, i am from australia, could i get the 220v drive for the amplifier ?

Accepted Answer

This is an 18 volt amp! Rig a wall wart to go between it and your local mains.
