But how do you calculate what a 4Ch amp would give it? For example, the Blaupunkt GTA 4 amp has a rating of RMS Power@4 ohms 4x60 / 2x180 watts. So how does that work? I am confused about how 4 channel means 240W RMS (4 x 60) but 2 channel means 360W RMS (2 x 180). In the above example with this amp, is it fair to say that if I connected two component speakers in the front, and one sub in the rear, the components would get 60W each, and the Sub would get 180W? (so total 300W RMS?) |

If you want to get the full 360W, you have to use the amp in 2-ch mode, i.e. both channels bridged. |

yes, that means your comps will get 60w each and the sub will get 180. |

So which one is right? For calculations sake, let's say I get the Blaupunkt GTA 480 which is rated RMS power (4 ohms) 4 x 75 W / 2 x 210 W. Would the config be #1 or #2? #1) Front components: 75W each Subwoofer: 210W #2) Front Components: 75W each Subwoofer: 150W (i.e. 75W x 2) |
