[QUOTE="Chromatic, post: 8209886, member: 659121"] Thank you guys for not "roasting" me on this question. It's the answer I was hoping for. I have a setup I'm about to buy (been shopping each part out for a while now..) and the amp runs 120watts RMS for each channel.. The front mid and high stage only take 100 RMS,... I'm running the single 10Inch sub in custom box sized for this car and sub, and this sub takes "Max" 300watt (Whether I get the w0 or w1 version, the power is the same). The amp I'm buying runs 400watts at stable 4 ohms when bridging two channels to 1 (ie: for the sub) -- Which is a clear 100 watts excess. So, this is a good thing! I'll have 20% headroom on Fronts, and 25% headroom on the single sub. So I'll set the amp at 80 percent for channels 1 and 2 respectively, and set it to 75% for channels 3 and 4 respectively.. and each speaker will receive it's proper load RMS when called upon,.. and the amp will never be worked harder than 80% (theoretically) of it's max capacity of *continuous* power... I'm not going to muddy this up with the "Peak power" figures. Last question then. Do most amps have ways to turn them "down" on wattage per channel? Or perhaps per 2 channels at least? Or will I be setting the amp at ONE percentage, and that is that. If the amp can only be set on one adjustment power wise for ALL channels output.. Would it be in my better interest to drive the amp at 85% and give the Sub 340watts.. and the Fronts 102 watts or drive it a bit higher to give the sub more, but simultaneously pushing more to the Fronts? Maybe that is a moot question if the typical 4 channel modern mid-range amp has ability to attenuate power per channel. Thanks for the answers! [/QUOTE]
