I have a JVC KD-APD58 head unit and it say 20w rms x 4(MOS-FET 50w x 4) does this mean i should get 20w rms speakers or 50 or either or neither...... What should i do.
Honestly, If you intend to use the Head Unit to power you speakers, i would go with the 20w RMS figure. So you would be happier powering lower end speakers with greater effeciency. Dont trust the Peak figure ok. you should get some decent sound but i always recommend using at least a 4 ch amp pushing 40w to power a little over road noise. good luch
