Re: How to choose an amp for speakers with different rms ratings?
Most any four channel amp has different gain adjustments for the front and rear channels. I'm running 60 watt rms speakers up front and 40 watt rms in the back, no problem. Just try and find a picture of the gain adjustment knob(s) on whatever amp you want to buy to see if it has separate front/rear gains.
Power is nothing without control.
