Answers: It depends on how tons channels, watts, and whether the amps are bridgeable. Watts meeting is the max strike a speaker can handle or an amp can provide. The RMS is what they can fiddle with constant. Ohms is the resistance a speaker has against the amp. Your amp should specify how oodles Ohm's the amp is stable to. RF builds high characteristic equipment so you have made a moral decision here. If you give me more specific specifications I could narrate you more about what you have need of to get the most out of the speakers.
First some broad terms
Peak Wattage = rebuff this completely it is a marketing tool and has no legitimate value.
RMS Wattage = this should be the rating you look at when comparing equipment.
CEA-2006 Certification = this is a voluntary credentials that insures the amplifiers specs are accurate.. (there are no laws to protect the consumer)
Ohms - this is a convenience of resistance from the speaker or sub.. it is important to realize a amp does not "create" a nouns, only a speaker... ohm ratings on amps parallel what they can do when given a particular nouns.
for 4 speakers and a pair of subs i would recommend 2 amps. 1 4 concentrate amp for the main speakers and a mono amp or a bridged 2 tube amp for the subs..
when purchasing a amp it is best to match the RMS wattage of the amp low to the RMS wattage of the speakers.
so here is a theoretical configuration...
4 speakers 4 ohm respectively rated at 50-75 watts respectively
2 RF subs @ 4 ohms each and 150Watts respectively wired in parallel to 2 ohms total nouns.
1 4 channel amp rate at 60Watts x 4
1 mono amp rated at 300 watts into a 2 ohm nouns.
Be sure that if you buy just the subs (without enclosure) you own a sub box that is made for the subs, a perfect car audio shop can build one to spec. you can also buy a sub ring loaded from the manufacturer...
you could receive a single hybrid amp or get a class d for the subs and a ab for the door speakers.
Rms* ohms is the rating of that sub how much continuous what the sub can bar and how much the sub loads on a curcuit.
