Does anyone know if the stock head unit in the 2005 cvo EG by (radiosound) push more power. I've heard 60 x 2. It seems to be a bigger unit from the inside of the fairing. Or would a new head unit really make a better sound system along with the arc amp that I already have. Can't get my fairing cover back on with arc amp on top of the head unit. Old unit is to dmm thick. Thanks for any input.
